I build web apps that touch real money and real users: Stripe billing with webhooks that can't double-fire, Supabase Postgres locked down with row-level security, Next.js App Router in production. 8+ years, 80 Upwork jobs, 100% JSS, Top Rated. Most of my work lands in one of these lanes: Payments - Stripe Billing, Checkout, Customer Portal, Connect. Production experience, including the unglamorous parts like idempotency and reconciliation. Full-stack builds - React / Next.js / TypeScript up front, Node.js / NestJS or Python behind, PostgreSQL / Supabase / MySQL underneath. Auth that works - Keycloak, OpenID Connect, NextAuth. Once fixed a broken production SSO nobody could touch for months; took 9 days. Shopify - checkout extensions and Shopify Functions, including a volume-discount engine written in Rust/WASM. Three public repos on my GitHub. Web3 - Solana and EVM, Rust, three years of it. Some numbers instead of adjectives: cut a fintech dashboard's heaviest route JS by 65%, shipped a 315-user internal portal to production in two weeks, my content sites score 98-100 on PageSpeed. I work async and in writing, with concrete updates - you always know where things stand. I use AI tooling heavily and openly, and I review every line before it ships. Speed without the slop. If it involves payments, auth, dashboards, Shopify checkout logic, or a Next.js build that has to actually ship, send it over and I'll tell you straight what it takes.
