Summary
👤
Senior🎓
Top SchoolDiego Fejgelis is a seasoned full-stack engineer and two-time founder with 14 years of hands-on experience building and scaling product-focused startups from Buenos Aires. He excels across the stack—shipping SPAs with React, designing Python/FastAPI backends, running Postgres-backed systems, and owning infra on platforms like Fly.io, Vercel and Supabase. Diego has led teams and projects that moved e-commerce and marketplace products to production-scale (ipsy, Cookapp, Goodmeal), driving measurable gains such as a 10x conversion uplift through data-driven experimentation. Recently he’s applied his expertise to GenAI healthcare chatbots and to real-time, high-ownership roles at fast-paced startups like Darma, where he built the main SPA, backend APIs, integrations (WhatsApp, Google), and the entire DevOps surface. Comfortable switching between coding, product specing, and operations, he brings founder-level ownership and a proven track record of turning ambiguous requirements into reliable, customer-facing systems.
