I’m a backend engineer with 8+ years building high-throughput payment and enterprise integration systems. I go deep on Java/Spring microservice platforms, async transaction flows, and reliability-focused development, with a particular strength in Direct Carrier Billing and payment gateway integrations at scale.

At Boku Network Services, I’ve shipped major internal and customer-facing capabilities—most notably re-architecting an internal configuration-management platform so config changes propagate to live systems in ~2 minutes. I integrated an end-to-end JIRA → GitHub PR → GitHub Actions deployment cycle, eliminating QA/Dev dependency for non-critical configs (~80%) and cutting delivery cycles by several days across 15+ carrier integrations.

I also lead security modernization across integrations, migrating from password/JKS authentication to mTLS + OAuth 2.0 without service downtime, and I’ve improved incident diagnosis by standardizing HTTP-response schemas. I mentor junior engineers, maintain 85–90% JUnit coverage, and contribute to sustained >99.9% uptime through on-call ownership—always aiming to reduce delivery friction and modernize security without downtime.
