About Me

Remote / Worldwide
9+ Years Experience

I build production software end-to-end. Over the last 7+ years I have delivered iOS mobile applications, and for the last 2+ years I have been creating backend platforms, AI systems and cloud infrastructure for startups and large-scale products.

My background started in native iOS development, but today I work across the entire product stack — from Swift mobile apps to Python backends, AI/RAG platforms, and cloud infrastructure. Projects include Fitbit (Google), Desk-Net, EVENET, and an AI Museum platform.

I enjoy taking ownership of products from architecture and implementation to deployment and production operations. I'm passionate about building reliable, scalable solutions that work in production.
