About

React/Next.js & AI Systems Engineer

I specialize in building, rescuing and scaling production React/Next.js products with AI workflows, PostgreSQL and cloud-edge infrastructure. I develop Mendelio, a Next.js 16/React 19/TypeScript platform on Cloudflare Workers and Supabase, including authentication, billing, real-time STT/LLM/TTS pipelines and GPU-backed voice operations. With 13+ years in software, I can own architecture, data modelling, implementation, testing, deployment and hard production debugging. I am a strong fit for React/Next.js modernization, AI and API integration, PostgreSQL performance, automation and system rescue. Flutter, Python, C#/.NET and C/C++ are supporting tools when the project needs them. I also lead Festapp development and contribute to FreeCAD, MapLibre, Crawlee and OHIF.

Work Terms

Available for one-off projects, short-term rescue work and well-scoped ongoing cooperation. I prefer clear milestones, written requirements and asynchronous communication, with calls when they help unblock decisions. Billing can be hourly or fixed-price after scope review.
