What I'm looking for

I’m looking for a role where I can lead backend delivery for secure, scalable cloud platforms—own architecture and reliability, mentor engineers, and build event-driven data systems with strong operational ownership and collaborative Agile teams.

I’m a Lead Software Engineer with 10+ years designing, developing, and operating secure cloud-based backend services, data-driven platforms, and distributed systems. I focus on scalable, available systems with operational ownership, clean code, documentation, and maintainable architectures.

In my recent role at Clarion Events, I led backend delivery end-to-end—owning technical direction, designing Kafka-style event-driven workflows, and building CI/CD pipelines with GitHub Actions, Docker, and AWS. I also mentor engineers through code reviews, pair programming, and automated testing practices, while handling production reliability, monitoring improvements, and incident investigations.
