Independent Software Consultant · Minneapolis, MN
I'm Nick Montelibano, founder of Fractal Logic. For over a decade I've architected and shipped safety-critical software for medical devices — embedded firmware, connected systems, and the compliance documentation that gets them through submission.
Daily drivers
Expertise
Medical device software demands both engineering depth and regulatory fluency. I bring both — so your team isn't translating between them.
Systems designed to scale from prototype to production.
Compliance built in from day one — not bolted on at the end.
Reliable firmware where resources are scarce and failure isn't an option.
Startup velocity with medical-grade rigor.
Process
A development process shaped by the V-model and a decade of taking regulated products to market — without giving up modern velocity.
Intended use, requirements, risk classification, and regulatory strategy — aligned before a line of code is written.
System design and hardware–software interfaces, with traceability from every requirement to its test.
Disciplined implementation: code review, CI/CD, and automated coverage from the very first commit.
Automated test frameworks and the V&V evidence your submission depends on — produced as you go, not after.
Submission support, post-market maintenance, and a codebase your team can carry forward without me.
Platforms
Connected medical devices don't stop at the firmware. I build across every layer a modern device touches — so nothing gets lost at the boundaries.
STM32, ESP32, nRF52 — bare metal and RTOS
Yocto-class embedded builds and desktop Linux
iOS & Android companion apps
.NET desktop applications
React, Astro, Blazor frontends
AWS & GCP connected-device backends
Contact
Whether you're taking a device from whiteboard to first-in-human, or need senior firepower to get an existing system through submission — I'd like to hear about it.
