You will get production-ready code from your AI-coded MVP
Project details
I fix AI-coded MVPs.
You used Cursor, Replit, Lovable, or v0 to build fast — and it worked. But now you're dealing with random crashes, spaghetti architecture, and impossible-to-debug errors.
I specialize in taking AI-generated prototypes and turning them into real, maintainable products. Not rewrites from scratch — surgical fixes that preserve what works and fix what doesn't.
What makes me different:
3+ years shipping production code at BMW, healthtech startups, and AI companies. I know what clean architecture looks like, and I know the patterns AI tools get wrong: missing error handling, no tests, duplicated logic, and infrastructure that doesn't scale.
My approach:
Audit first — I tell you exactly what's broken and what's fine
Honest assessment — Prioritized fix list with realistic timelines
Fix systematically — Weekly updates
Clean handoff — Documented code your team can maintain
I won't upsell you on a full rewrite if you don't need one.
If your MVP is on fire, let's talk.

Product-Minded Full-Stack Engineer | AI-NATIVE - Fast Delivery
Buenos Aires, Argentina - 11:48 pm local time
from architecture decisions to deployment.
Most recently at Critical TechWorks (BMW Group), where I built and
maintained the Spotify integration for BMW's in-car entertainment
system. Distributed systems, event-driven architecture, TypeScript,
production incidents from drivers across multiple countries.
Before that I designed and built a multi-tenant healthcare platform
from scratch — patient-facing mobile intake, AI-powered clinical
screening, and a medical staff dashboard — working directly with
doctors to get the workflows right.
My stack: Node.js, Next.js, TypeScript, Python, AWS serverless
(Lambda, S3, DynamoDB), PostgreSQL, REST APIs. Increasingly
working with AI integration — RAG systems, LLM APIs, vector
databases.
I work best on projects where the problem is well-defined and the
team wants someone who can think about the product, not just
execute tickets. Available for both project-based work and ongoing
engagements.
