About this gig

You have an idea. I turn it into a real product your users can sign up for and pay for.


I am a senior full-stack developer who has shipped two AI SaaS products solo (SnapSkill and FlowSense) with real authentication, Stripe billing, and production databases. I do not hand you a template wrapper; I build a clean, deployable Next.js codebase that you fully own.


What you get is a Next.js and TypeScript app with Clerk authentication, a Postgres and Supabase database, a REST API, and a responsive UI, all deployed live to Vercel. Standard adds a CRUD dashboard and Stripe subscriptions with webhooks. Premium adds multi-tenant architecture, Stripe Connect, internationalization, automated tests with Vitest and Playwright, Sentry monitoring, plus a security and RLS review.


Every delivery includes the full source code and a Loom walkthrough so you can run, extend, and deploy it yourself. Message me your idea before ordering and I will confirm scope, timeline, and the right package for you.

I'm a full-stack developer with 6+ years' experience, based in Portugal, having worked with teams in the UK, Netherlands and Germany. My edge: I've shipped TWO complete AI SaaS platforms solo, end-to-end — SnapSkill and FlowSense — both live on Next.js, TypeScript, Node/NestJS, the Anthropic Claude API, Stripe, Clerk and Supabase. Hire me and you get someone who ships the whole thing: auth, payments, database, AI and deploy. I fix and deploy broken apps, integrate Claude or OpenAI, and build production SaaS. Clear scope, honest timelines.
