about

Engineering systems that don't flinch under load.

I'm a Senior Software Engineer with 6+ years spent close to the hard parts of distributed systems — the ingestion paths that must never drop an event, the pipelines that carry terabytes a day, and the deployments that can't afford downtime.

My work centers on event-driven architecture with Kafka and Redis, non-blocking, reactive services in Spring WebFlux, and the cloud-native tooling — Kubernetes, Terraform, CI/CD — that keeps them shipping safely. I care about the parts users never see: partitioning strategies, retention, backpressure, and the observability that makes an incident a five-minute fix instead of an outage.

Along the way I've owned architecture for platforms serving 1M+ voice calls a day, scaled log-processing ingestion for security integrations, and mentored engineers toward the same standard of resilience.

experience

A track record built in production.

Six years across security, communications, and enterprise platforms — always on the systems that have to stay up.

PROJECT / 01

Illumio

Spring WebFluxJavaKafkaRedisPostgreSQLR2DBCKustoDBKubernetes

A large-scale distributed log-processing platform handling terabytes of data daily across Check Point, Palo Alto, Fortinet and more.

  • Architected and scaled a high-throughput audit-event ingestion service using database partitioning, retention strategies, and Kubernetes lifecycle orchestration.
  • Built a Flow Pipeline Validator Service ensuring logs were reliably processed end-to-end from source integrations to downstream storage and policy systems.
  • Cut processing latency with Redis caching, eliminating redundant external I/O to databases and downstream services at scale.
  • Built non-blocking ingestion APIs with Spring WebFlux + R2DBC, and scaled the API Gateway with JWT-based auth.
