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.

For around 10 years already, I have helped countless customers build all sorts of systems, including human systems; engineering teams that perform and deliver. In the age of AI, harnessing its capabilities will be a key component of every successful business. When hiring a successful candidate to help you build your infrastructure and software you will want to assess their critical thinking, proactivity, reliability and ability not only to use AI but every tool they pick. These are abilities you can find all around the world, but the task to find the talent might feel difficult or even overwhelming. Due to culture, timezone and education differences. I help you find the needle in the haystack, the top performers, the diligent workers, the easy to communicate with folks that are a gem and will accompany you for years in your organization. This is about suitability and proper fit. Specially within small to medium organizations that are looking to disrupt a niche or section of an industry. Adding a single Engineer to your team nowadays can represent a significant increase in your output thanks to AI. So from now to when AI is completely autonomous, for which I think we still have at least a decade (or half of that at minimum)... adding Engineers is still crucial, but adding the right Engineers is still one of the most important things you can do for your organization.
