What I'm looking for

I am looking for backend roles focused on building reliable, observable Java services, ownership of production systems, strong CI/CD practices, and opportunities to improve performance and incident response.

I am a backend engineer focused on building reliable, observable Java Spring Boot services for financial systems.

At Oracle I owned production release validation and post-deploy verification for multiple Spring Boot financial services, triaged P1/P2 incidents, and delivered RCAs within 24–48 hours while reducing repeat incidents by 30%.

I have designed and developed backend services and integrations handling high transaction volumes, standardized logging and correlation IDs to cut investigation time, and improved CI/CD pipelines to reduce failed releases by 25%.

I build with a focus on performance and observability—optimizing queries, implementing pagination and indexing to improve P95 response times by 40–60%—and I document runbooks and onboarding guides to accelerate team ramp-up.
