What I'm looking for

I’m seeking remote roles only. I’m a U.S. citizen and don’t require sponsorship.

At Bright Vision Technologies, I own backend delivery for production services using Java 21, Spring Boot, and Apache Kafka. I design microservices and event-driven workflows, and build secure REST integrations with AWS services.

I improve response time and production stability through JVM profiling, SQL tuning, caching, tracing, and root-cause analysis. I also lead design and code reviews, mentor engineers, and contribute to incident resolution and technical planning.

Before Bright Vision Technologies, I developed backend services at 3Pillar Global, Intellibus, and Tsunami Tsolutions. My work included Kafka-based event processing, Redis caching, REST APIs, database performance improvements, and automated testing.
