Summary
👤
Senior🎓
Top SchoolGabriel Jaldon is a Lead Security Researcher and seasoned engineer with 12+ years building scalable, production-grade systems across distributed databases, Elixir/Phoenix backends, and AI integrations. A self-taught developer who practices Kaizen, he combines pragmatic engineering with a strong bias for maintainability, performance tuning, and cost optimization—having saved teams tens of thousands monthly through data modeling and migrations (e.g., Cassandra to ScyllaDB). He contributes to prominent open-source Elixir projects (Phoenix, Ecto, Postgrex, Plug) and maintains tooling like ecto_enum and a Heroku Phoenix buildpack, reflecting deep expertise in both library design and deployment automation. Comfortable working remotely across time zones, he thrives with autonomy, clear communication, and mentoring while bringing a security-first mindset from recent Web3 and research roles. An unusual strength is his cross-domain fluency—from low-level OS and TCP/SSL connection handling to high-level GraphQL and background processing—allowing him to diagnose thorny production issues end-to-end.
