Senior Full-Stack Engineer in Berlin.
TypeScript, React, Next.js and Node.js. Three products shipped solo, all live.
6 projects, each built alone. 3 run live today.
A deployed multi-tenant SaaS where an LLM extraction pipeline turns PDF and DOCX contracts into typed, structured data that drives a deadline and alert system.
Layers built
A deployed SaaS that adds an embeddable "listen to this article" audio player to blogs and digital media, powered by a multi-provider TTS pipeline.
Layers built
A trading workstation on a live Argentine broker API: a rebalance engine turns analyst signals into orders, and nothing reaches the broker until a human confirms it. The analyst backend is a fork of the open-source ai-hedge-fund project.
Layers built
An AI job-search platform for the Argentine market: a resume-tailoring product paired with a companion pipeline that mines job-search communities for product ideas.
A study curriculum I assembled for the AWS generative AI certification: 26 lab scaffolds with reference solutions, covering retrieval, an agent loop, guardrails and LLM-as-judge evaluation. I am still working through it.
A daily pipeline that scans job-search subreddits and Hacker News, extracts actionable product ideas with Claude in a single structured call, and emails a ranked digest.
Why the evaluation harness, not the base model, decides whether an AI feature ships.
Engineering
