You have a product that needs to work. Not a prototype, not a demo. Something real users pay for and depend on daily. That is what I build. 5+ years shipping production SaaS platforms, marketplaces, and web apps. I started on the frontend, moved into the backend, and now I build the whole thing. I spent 3+ years building an NFT marketplace used by millions. Redesigned the entire frontend, then moved to the backend where I shipped renting systems, search infrastructure, payment migrations, and on-chain transaction processing. On Upwork, I have delivered for 20+ clients across SaaS, real-time marketplaces, creator platforms, and auction systems with live bid sync. I flag problems early, ask questions before writing code, and keep you in the loop without being asked. What I bring: - Subscription billing, usage gating, and Stripe webhook flows built end-to-end - Real-time features, payment integrations, and CI/CD pipelines running in production - Admin dashboards with RBAC, analytics, and complex relational filtering - RLS policies, server-side enforcement, webhook signature validation. Security is not an afterthought - Responsive, component-driven frontends with clean state management and design system integration - Integration tests over mocks, E2E for the flows that actually matter Stack: Next.js · Nest.js · Node.js · TypeScript · React · PostgreSQL · Supabase · Firebase · Stripe · Prisma · AWS · Vercel Also work with: React Native · GraphQL · Redis · GitHub Actions · Tailwind CSS · Jest · Playwright I am currently building with AI tools, integrating LLMs, agents, and RAG pipelines into real products. This is where I am heading, and I am actively shipping projects with Anthropic API, OpenAI, and LangChain. If you need someone who takes your project as seriously as you do, message me. Happy to discuss the scope before you commit.
