Summary
👤
Senior🎓
Top SchoolHelder Esteves is a senior full stack engineer based in Lisbon with 8+ years building scalable web platforms and systems-level instrumentation. He holds a Master’s in Electrical and Computer Engineering and has repeatedly owned end-to-end products—from a social media site he grew from 0 to 20k monthly users with real-time messaging and live calling, to analytics instrumentation for the World Poker Tour. Comfortable across React/Next/Vue, Node.js, PostgreSQL and cloud platforms, he has driven product adoption, revenue, and security milestones (including work that supported ISO 27001 outcomes). Helder combines hands-on implementation with product intuition—he’s as likely to prototype a realtime feature as he is to design the telemetry that measures its impact.
