Senior🎓
Top SchoolUlysse Prygiel is a senior software engineer and former YC S20 co-founder with 11 years of full‑stack experience building production web and mobile systems. He’s shipped end-to-end products as a founding engineer and CTO-on-demand, oscillating between frontend UIs and event-driven backend microservices using TypeScript, Node.js, NestJS, GraphQL and PostgreSQL/MongoDB. Comfortable in early-stage startups and product‑focused teams, he’s implemented non‑blocking retry mechanisms with Kafka, Shopify integrations, and Chrome extension tooling for AI-assisted flows. Based in Barcelona, he combines entrepreneurial instincts with hands‑on architecture and infrastructure work—often extracting monolith pieces into scalable microservices—and brings a practical eye for shipping reliable systems under ambiguity.
