About
AI Engineer, IoT Architect
& Mobile App Developer
I'm a freelance software engineer and consultant with 11+ years of experience building products at the intersection of AI, mobile, and connected devices. I work with startups, product teams, and enterprises to deliver reliable software — from AI agents that automate complex workflows to BLE-enabled hardware and real-time IoT platforms.
My work spans the full stack of connected product development: designing AI-powered workflows that reason and act autonomously; building production-grade iOS, Android, and Flutter apps with polished UX; engineering BLE communication layers for sensor networks and industrial equipment; and architecting cloud backends that handle real-time data at scale. I've contributed to Eclipse Vert.x, developed BLE SDKs at Nordic Semiconductor, and delivered IoT platforms for industrial clients.
I take projects from concept to deployment — handling architecture, implementation, testing, and launch. If you're building something that connects software to the physical world, or bringing AI into a product experience, I can help you ship it right.
