What I'm looking for

I’m looking for a role where I can own backend platforms end-to-end APIs, event processing, ETL, and observability, scale cloud infrastructure reliably while delivering secure workflows.

I’m a Senior Software Engineer with 5+ years of experience owning systems end-to-end—from API architecture and distributed event processing to DevOps automation, observability, and production reliability.

In my recent role, I increased platform engagement by 20% by designing and deploying scalable Node.js/TypeScript APIs, and I reduced worst-case PostgreSQL query latency by 99.5% through index redesign, join optimization, and refactoring high-volume reporting queries. I also integrated Braintree and PayPal into production services to support secure multi-method checkout, subscription billing, and transaction management for international users.

I modernize legacy workers and build resilient infrastructure: I’ve processed millions of daily distributed events with zero production outages by improving worker infrastructure, and I’ve built distributed observability with OpenTelemetry and ClickHouse to centralize tracing and monitoring. I enjoy turning complex workflows into reliable pipelines—developing ETL pipelines and distributed workers, and delivering real-time capabilities with WebSockets where needed.
