I build fault-tolerant Go systems for high-volume payments and consumer platforms.

At Zamp, I migrated live payout execution to Temporal with zero downtime, fenced six concurrent legacy cron runners, and retired the old path. I also built US payment rails across ACH, Fedwire, RTP, and SWIFT, alongside a multi-partner KYB onboarding platform.

Previously at Probo, I built event-driven services for a real-money opinion trading platform serving 2.5M+ users. I delivered a RabbitMQ-backed notification service sustaining 100,000 notifications per second at 98% delivery and tuned trading services from a 2 million requests-per-minute breaking point to 6 million sustained requests per minute.

I work Go-first across distributed systems, durable workflows, APIs, Kubernetes, PostgreSQL, Redis, and production observability. I focus on what systems do when dependencies fail, using idempotency, retries, reconciliation, and clear operational ownership to make high-volume services reliable.
