Summary
👤
SeniorAlexandre Costa is a Senior Software Engineer with 12 years of experience specializing in scaling data-intensive web applications and improving developer experience. He blends hands-on coding with pragmatic team leadership, having led backend restructures and grown teams 3x while preferring to stay close to the codebase. His work emphasizes simplicity, fast feedback loops, and measurable productivity gains—examples include cutting dashboard latencies from a minute to milliseconds and making test/compile cycles multiple times faster. Deeply curious about the Erlang VM, Postgres and Redis, he routinely tackles distributed caching, stream processing and zero-downtime migrations. A former co-founder and teacher, he pairs academic training in optimization with practical production instincts and a habit of “deleting more code than he writes” to keep systems maintainable. Based in California and now at Apple, he’s known for quick prototypes that reveal hard trade-offs and for evolving toward more empathetic, metrics-driven leadership.
