  • Engineering Organizations Pt 1: Service Firms - When You Are the Product

    Engineering Organizations Pt 1: Service Firms - When You Are the Product
    Feb 18 2026
    In this first part of a two-part series, Jeff and Luca explore how different types of service-oriented engineering organizations should focus their learning and improvement efforts. Drawing from their consulting experience, they examine three distinct categories: product development firms that turn client ideas into reality, engineering development firms that sell specialized technical expertise, and solo engineers who package all necessary knowledge into one person.The core insight: what you should focus on learning depends entirely on what you're actually selling. Product development firms need to master the entire client journey and product design process, not just engineering excellence. Engineering development firms must become technical wizards in a specific domain that clients actually value. Solo engineers face the challenge of needing deep expertise while wearing every business hat. Across all three types, the common traps are the same: focusing too much on craft and too little on client experience, failing to specialize, and not investing enough in teaching as marketing.Throughout the discussion, Jeff and Luca emphasize that for service firms, you are the product - and that changes everything about where you should direct your improvement efforts. The conversation is grounded in real experiences, including some cautionary tales about firms that tried to be everything to everyone.Key Topics[00:00] Introduction: Two-part series on engineering organizations and their different focuses[02:30] Overview of the framework: Service firms vs. product-building companies[05:15] Product development firms: Why engineering excellence isn't enough[08:45] The critical importance of product design and client guidance over pure engineering[12:20] Process-level learning: Shortening cycle times and enabling rapid prototyping[15:40] The Irinos example: In-house board manufacturing to tighten feedback loops[18:30] Requirements will always change - designing for learning, not perfection[21:00] The danger of being a generalist: Why specialization matters for service firms[24:15] Engineering development firms: Selling technical expertise, not complete products[27:45] Technology-focused learning: Going deep on specific technical capabilities[30:20] The trap of becoming a commodity: Why domain expertise beats technology alone[33:40] The forklift invoice review example: You can't specialize too narrowly[35:30] Solo engineers: The complete package vs. temporary employee trap[39:00] Common failures across all service firms: Too much craft focus, too little client experience and marketing[41:30] Teaching as the best form of marketing for technical service firmsNotable Quotes"The customers don't actually hire them for their engineering skills. They are sort of a given. But what such a product development firm should offer the client is guiding them through the development process, which they don't have enough skills for to do it on their own." — Luca"Engineering is not the point. The unit of work is delivering a working product to the client that satisfies their business case, that has a reasonable cost to manufacture, and that you feel confident your own client has validated their market." — Jeff"It's not that engineering is irrelevant, but rather that it's table stakes. This is just taken for granted, but what such a product development firm should offer is guiding them through the development process." — Luca"You almost can't be narrow enough. I remember our friend Philip Morgan having this example of a company that specializes in reviewing invoices of forklift repairs. This is what they do. They review forklift repair invoices. And they're doing very well apparently." — Luca"Teaching and giving information and solving problems publicly is the best form of marketing. It's not advertising. It's building trust with an audience." — JeffResources MentionedIDEO - Prototypical design firm mentioned as an example of companies specializing in product designIRNAS - Product development firm with in-house board manufacturing capabilities, featured in previous episodes, exemplifying tight feedback loopsPhilip Morgan - Consultant and friend mentioned for his example about specialization (forklift invoice review company)Jeff Gable's website - Jeff's consulting services for medical device software development and advisoryLuca Ingianni's website - Luca's training products and resources for embedded systems, IoT, and AIConnect With UsStay tuned for Part 2, where we'll explore organizations that build products and what they should focus on when the market decidesIf you're in the medical device industry and need help with embedded software - either writing it or navigating the regulatory landscape - reach out to Jeff at jeffgable.comCheck out Luca's training products for embedded systems, IoT, and AI at luca.engineerReflect on your own organization: Are you focusing on the right things for the type of service firm you are?

  • Rust with Milica Kostic

    Rust with Milica Kostic
    Jan 19 2026
    In this episode, we sit down with Milica Kostic, an embedded software architect from Belgrade, Serbia, to discuss her journey from C/C++ to Rust and what it means for embedded development. Milica shares her experience adopting Rust in production environments, starting with an embedded Linux project using a microservice architecture that allowed for clean isolation of Rust code.We explore the practical realities of learning Rust as an experienced C/C++ developer - yes, there's a learning curve, and yes, the compiler will slap you on the wrist frequently. But Milica explains how the development experience, with cargo as a package manager and built-in tooling for testing and static analysis, makes the journey worthwhile. She's candid about where Rust shines (embedded Linux, greenfield projects) and where challenges remain (microcontroller support, IDE tooling, vendor backing).The conversation touches on the bigger question facing our industry: with memory safety becoming critical in our connected world, what role should Rust play in new embedded projects? While Milica takes a measured stance - acknowledging that C and C++ aren't going anywhere - she's clearly excited about Rust's potential, especially in safety-critical domains like medical devices. Whether you're Rust-curious or still skeptical, this episode offers a grounded perspective from someone who's actually shipped production code in Rust.Key Topics[02:30] Milica's background in embedded systems and her journey from electrical engineering to embedded software development, with focus on safety-critical industries like medical devices[04:15] The path to adopting Rust: from first hearing about it in 2020 to finding a client project willing to embrace it, and the importance of having experienced Rust developers on the team[07:00] Choosing the right project for Rust adoption: embedded Linux with microservice architecture as an ideal starting point, avoiding complex C/C++ interoperability[10:45] The learning curve: getting used to the Rust compiler's strictness, discovering the ecosystem of unofficial but widely-used crates, and how learning Rust improved C++ skills[14:20] What makes Rust development pleasant: cargo as package manager, built-in testing and static analysis, cleaner code organization with modules, and writing unit tests alongside source code[17:30] Current limitations: lack of official vendor support for microcontrollers, community-driven development, potential gaps in certified stacks (like BLE), and IDE support challenges[20:15] Interfacing Rust with C and C++: C binding works well, C++ has limitations with inheritance and templates, and the safety considerations when using unsafe code blocks[25:40] Integrating Rust into legacy projects: when it makes sense (isolated new features requiring memory safety) and when it doesn't (just for experimentation), plus maintenance considerations[30:00] The big question: Is it irresponsible not to use Rust for new projects? Discussion of Philip Marcraff's strong stance and Milica's more nuanced view considering team knowledge, existing tooling, and project context[33:45] The influence between languages: how C++ is learning from Rust's memory safety features, and why the borrow checker is harder to retrofit than basic safety improvements[36:20] Rust in operating systems: adoption in the Linux kernel and Microsoft Windows, and major tech companies pushing C++/Rust interoperability forward[39:00] The future of Rust in embedded: Milica's view that C, C++, and Rust will coexist, each with their own use cases, advantages, and trade-offsNotable Quotes"Learning Rust has also made me a better C++ developer as well. Once you get used to those rules, you apply them in C++ as well." — Milica"Just like writing Rust code is pleasant. It flows much nicer than or easier than it would with C++, for example. The way you organize your code, in my opinion, is also cleaner." — Milica"If you are developing Rust for embedded systems on microcontrollers, you need to be aware that there is no official vendor support. Everything currently is open source and driven by the community." — Milica"You definitely do not lose benefits of using Rust for the rest of your codebase when using a C library. That C library is isolated, and if there are some memory issues, then you know where to look." — Milica"I think most of the benefits come from starting with Rust in the first place. So having a clean slate, starting a new product, new project with Rust. That's where you see the most benefits." — MilicaResources MentionedEmbassy - An async framework used in embedded Rust projects, mentioned as a good starting point for greenfield embedded developmentZephyr RTOS - Real-time operating system that is working on official Rust integration, though not fully there yetRust Rover - JetBrains' official IDE for Rust development, released about a year and a half ago, though with some limitations for embedded developmentZed - A new IDE ...

  • MicroPython with Matt Trentini

    MicroPython with Matt Trentini
    Jan 5 2026
    We talk with Matt Trentini, Principal Software Engineer at Planet Innovation, about using MicroPython for professional embedded development—including medical devices. Matt shares how he was drawn back to embedded development after becoming jaded with traditional C-based workflows, and explains why MicroPython's interactive REPL and rapid development cycle have become game-changers for his team.We explore the practical realities of using an interpreted language on microcontrollers: how Planet Innovation uses it for Class B medical devices, what the performance trade-offs actually look like, and how features like the Unix port enable robust testing. Matt walks us through deployment considerations, explains how to integrate C code when needed, and shares compelling stories about real-time client demos that would be impossible in C++.Whether you're skeptical about high-level languages in embedded systems or curious about alternatives to traditional development workflows, this conversation offers a grounded, engineering-focused look at what MicroPython can—and can't—do in production environments.Key Topics[03:30] Matt's background and why he left embedded development before MicroPython brought him back[08:45] What MicroPython is: a complete re-implementation of Python for microcontrollers with REPL, filesystem, and machine module[13:20] How Planet Innovation introduced MicroPython through an OpenMV vision processing project[17:15] The game-changing power of the REPL for interactive hardware development and testing[21:40] Running MicroPython code on x86 for testing, and the mock machine library approach[26:30] Python library compatibility: what works, what doesn't, and memory considerations[29:50] Integrating C and C++ code through extension modules for performance-critical sections[33:10] Performance realities: 10-100x slower in interpreter, but can always drop to C speed when needed[37:45] Tooling: MPRemote, the magical mount feature, and development workflow[42:20] When NOT to use MicroPython: cost-sensitive high-volume products and resource constraints[45:30] Using MicroPython in Class B medical devices and safety-critical applications[49:15] Garbage collection: simple, predictable, and controllable—can be disabled when needed[52:40] Real-time client demo story: modifying state machines during a call and showing results immediately[56:20] Deployment: frozen code, disabling REPL and filesystem, and OTA considerations[01:01:30] Common mistakes: logic errors and inadvertent allocations rather than memory corruption[01:05:45] Threading, AsyncIO, and the Global Interpreter Lock across different ports[01:08:20] State machine frameworks: StateChart, Yasme, and PyTransitions[01:11:40] Junior developer productivity: faster onboarding compared to C/C++ embedded development[01:15:10] Getting started: board bring-up as an ideal first use case for MicroPython[01:17:50] Hardware-in-the-loop testing as a low-risk way to try MicroPythonNotable Quotes"It's hard to overstate how game changing the REPL is. Particularly as an embedded engineer, once you see that you can interactively talk to a peripheral, you can generate your own I2C, squirt it across and see what the peripheral does with it—suddenly driver development has just become easy to experiment with." — Matt Trentini"My trite answer is that MicroPython is slow—10 to 100 times slower than C in the interpreter. But my flip side answer is that it can always be made as fast as C because you can always drop into C to write things." — Matt Trentini"There was a moment in a recent project where we were discussing the workflow of a state machine with the client, and while we were on a call, another engineer was actually making changes to MicroPython code. Literally a couple minutes after we'd been hashing out the details, they showed the changes in the state machine using the REPL. The client was blown away—in 25 years of development, I have never had that kind of turnaround in C and C++." — Matt Trentini"If you want to make a good friend of your electronics engineers, give them a build of MicroPython that can run on their custom board. In the past, they would typically be waiting for weeks or sometimes months before a software resource could be assigned. Now I can turn around a MicroPython build in a day or two, and they can test I2C, GPIOs, and UARTs themselves." — Matt Trentini"The irony is that the people who have embedded C knowledge are actually the people that can benefit the most from MicroPython. It's like having a superpower—you understand what MicroPython is doing in the background, you know you're just effectively writing a lot less code." — Matt TrentiniResources MentionedMicroPython Official Site - The official MicroPython project website with documentation and downloadsOpenMV - Computer vision project using MicroPython for camera-based applicationsMPRemote - Tool for interacting with MicroPython devices, including the magical mount ...
