Experiência profissional
Backend and API Engineer, Claude Code
Agency • Freelance
Apr 2026 - Present • 4 mos
Build production backend systems and data pipelines for clients who need real infrastructure, not another chatbot demo. Work includes RAG pipelines that ingest and chunk documents into a vector database and answer only from what they actually retrieve, FastAPI backends with proper rate limiting and error handling, and internal dashboards connecting tools like Shopify, Xero, or CRM platforms. Claude Code accelerates the implementation, while the retrieval logic, data model, and security decisions stay something I design and verify by hand rather than leave to the model.
Shopify and Mobile App Developer, Claude Code and Cursor
Marketing • Freelance
Jan 2026 - Jul 2026 • 6 mos
Build and maintain Shopify storefronts and React Native and Flutter mobile apps using Claude Code and Cursor as daily tools. On the e-commerce side, this means turning finished Figma designs into fully custom, responsive Shopify sites rather than generic themes. On mobile, this means stabilizing apps that are close to launch but blocked by crashes, broken state management, or API integration bugs, fixing and testing across iOS and Android before signing off. Every project ships with clean, reusable code so future updates don't mean rebuilding from scratch.
Claude Code Full Stack Developer
Agency • Freelance
Nov 2025 - Feb 2026 • 3 mos
Build production SaaS and web applications for clients moving from prototype to a real, multi-user product. Core stack is Next.js and Supabase, with Claude Code as the daily development tool from first commit to deploy. Own authentication, role based access control, and row level security so client data stays properly isolated between users, and every AI generated change gets reviewed and tested before it ships. Recent work includes rebuilding an internal dashboard on Supabase and Vercel, and taking a founder's MVP from a rough Figma file to a deployed, working application with a documented handover.
