15+ years as a software engineer, now a PhD candidate in computer science. I specialize in:

- Web & mobile apps (React, React Native, Next.js, Zustand, TypeScript)

- High-performance systems (AI, Python, C++, Dask, NumPy)

- Project leadership (10+ years managing teams and timelines)

- Clients served: Fintech, insurance, oil & gas, retail (web/mobile apps at a major software firm)

I can help with technical challenges, process improvements, or research-driven prototypes (MVPs, proof-of-concepts). While I'm equipped for high-performance or distributed computing tasks, I particularly enjoy full-stack web and mobile projects—those come naturally to me. Open to short-term or long-term freelance work.

Portfolio available upon request.

Got an embedded programming or hardware design challenge you need solved? I'll solve it!

15 years of experience consulting, and I've seen it all; for the past decade I've been exclusively consulting independently. Past clients have included companies large and small, with everything from green-field ideas for new products to tricky situations with existing products they needed fixed. Comfortable working under regulatory constraints; many of the projects I've worked on have been medical devices.

C is my bread and butter on the embedded side, and Python is my go-to for developing PC utilities and scripts, but I'm comfortable working in a lot of languages from assembly all the way up to Javascript when needed. I can even patch embedded binaries by hand when needed.

Architectures? Well, these days it's mostly ARM Cortex, but I've done everything from 8051 and 6502 to STM8 to PIC16/24 to all of the modern stuff, plus a handful of really obscure things. Specific chip families that I've dealt with a lot lately include STM32, nRF5x, and PIC16, but again, I've successfully worked with MCUs from ST, Nordic, NXP, SiLabs, Renesas, Atmel, Microchip, and various other vendors.

Super comfy with Linux, though most of my practice is bare-metal or with true RTOSes.

Bespoke drivers need development? No problem. USB, I2C, SPI, CAN? Yup, all of those and more. BLE, LoRa? Expert. Power optimization for battery operation? That's a specialty of mine: I squeeze out every last nanoamp -- and quantify the improvement.

BS in EE. Designing analog and digital circuits, laying out PCBs, bringing up boards, debugging hardware, simulating designs (including EM simulations for antennas, transmission lines, etc.), and consulting on hardware improvements are all no problem. I have an extremely well equipped EE lab bench, including for RF out to 8 GHz, and am very comfortable doing fine-pitch soldering under a microscope as needed.

US citizen, masters from Stanford. Licensed professional engineer (PE) in Colorado.

Feel free to reach out and let's see if there's a good fit. Thanks!

Versatile back end code and infrastructure development services. Typical deliverables are Dockerized microservices specified by OpenAPI, written in Go or Python, with a REST/JSON API and backed by PostgresDB or MySQL. And of course your custom business logic.

I take your OpenAPI spec and implement it, or I can help you develop your back end infrastructure from the ground up. Basically I offer back-end componenets you can slot into your Kubernetes or Docker environment from day one.

On the business side, you get a fractional developer for a no-haggling fixed monthly rate, corp-to-corp billing, long term support for your code, careful vetting of dependencies for licensing and security, and a professional approach to your technical needs.

If you have more complex needs, e.g. project or team management please reach out as I have extensive career experience in all aspects of of technology development and management in startups and large enterprises. Need a contract manager or CTO perhaps?
