I build reliable financial and SaaS platforms with Elixir, cloud infrastructure, and observability.

Message

I've built and maintained financial platforms at BS2, migrating an acquired platform into GCP while improving file transmission resilience, observability, and operational automation.

As a short-term contractor at Supabase, I implemented OpenTelemetry-aligned telemetry capabilities for Logflare, resolved scaling bottlenecks, and contributed to Elixir open-source projects. Previously at Credisis, I optimized concurrent processes and SQL queries, in some cases accelerating processing by thousands of times.

At Softaliza, I led the back-end team for the company’s largest product, helping drive more than 6x annual revenue growth. I’ve also led microservices migration, defined API standards, built CI/CD pipelines, configured production infrastructure, and mentored teammates through complex technical work.
