I’m a Backend Engineer focused on distributed, event-driven systems in Java, building reactive microservices with Spring WebFlux and Project Reactor. I’ve worked on multi-tenant SaaS architectures on Azure and designed reliability-first pipelines where correctness under failure is non-negotiable.

At Blue Yonder, I’ve been a core engineer since inception on a greenfield, pre-launch platform. I owned an at-least-once reactive Apache Kafka pipeline with per-tenant fault isolation, delivering 99.99% SLA and keeping duplicates safely low through partition-order processing, careful offset commits, and tenant-scoped recovery.

I also built a multi-tenant configuration service with hot-swapping across microservices via Kafka broadcast, eliminating restarts by treating every config change as a message. In the solver layer, I engineered a reactive orchestration scheduler with lock-free coordination to prevent overlapping and duplicate runs, isolating failures per tenant so one failing tenant never stalls the rest.

Beyond production work, I built and open sourced a distributed job scheduler and chaos-tested it to sustain ~100 fires/sec with zero duplicate executions under failure injection. I mentor engineers across WebFlux, Reactor, and Kafka, and I’m passionate about engineering systems that are observable, testable, and resilient from day one.
