What I'm looking for

I'm looking to build and support production-critical Java platforms where I can improve reliability, resolve complex distributed-system issues, automate delivery, and collaborate closely with engineering, QA, operations, and product teams.

I've built and supported production Java platforms at Nexthop AI, Circle, Square, and Arista Networks, spanning AI cluster networking, USDC multi-chain infrastructure, payment processing, and cloud networking. My work has improved integration reliability, transaction validation, release predictability, and recurring incident reduction through hands-on engineering and root-cause analysis.

I develop Java and Spring services, APIs, database integrations, automated tests, and production fixes across Linux and cloud environments. I enjoy working closely with engineering, QA, operations, and product teams to turn complex application, transaction, and networking failures into reliable releases and maintainable solutions.
