Over mij
Full-stack engineer, backend-focused: Node.js, PostgreSQL, APIs, microservices, Docker. Frontend: React, Next.js, Supabase. I handle what breaks if rushed — Stripe payments (Checkout, subscriptions, webhooks) and Postgres/Supabase Row Level Security. Also add OpenAI/LLM features to existing products. Proof: shipped a full SaaS app end-to-end — auth, RLS, Stripe subscriptions, gated features, live. Demo + source in my portfolio. Previously CTO at MySoft. Roots in ACM competitive programming — precise, tested code. Send your project — I'll tell you honestly if and how fast I can help.
