Nest.js, AWS (Lambda, DynamoDB)
What I can help you with
🚀 Bootstrapping web products
From V0/Lovable prototypes to clean, scalable, professional-grade implementations — transforming quick AI-generated drafts into structured, long-term architectures.
🧹 Refactoring AI-generated codebases
Code cleanup, architecture improvements, security review, and setting up guardrails for sustainable AI-assisted development.
⚡ Accelerating feature development
End-to-end feature delivery — independently or embedded within your team.
I’m currently offering competitive rates for short missions (< 1 month) to quickly build my freelance portfolio. For longer engagements, my rate is 350€/day.
