Software engineer focused on Elixir/OTP fault-tolerant distributed systems and high-availability APIs.
MexicoWhat I'm looking for
I’m a software engineer specializing in Elixir/OTP and fault-tolerant distributed systems design. I’ve built and scaled high-concurrency backend services for sensitive fiscal workloads, with a strong emphasis on reliability and transactional correctness.
At Diverza, I led backend engineering for financial systems, using OTP (GenServer and supervision trees) to deliver 99.9% system availability. I also designed critical refactoring flows with Ecto and Ecto.Multi—ensuring transactional integrity between SQL Server and PostgreSQL—and reduced manual reconciliation operations by 40%.
Most recently, I designed and deployed Karaokreator, an AI karaoke SaaS, end-to-end and solo. I implemented an asynchronous AI/GPU pipeline using Phoenix + Oban + Redis + Python workers on Modal/GPU, including Stripe billing and HMAC-signed, idempotent webhooks, with infrastructure on Fly.io and Cloudflare R2.
