I engineer high-concurrency systems designed to thrive under pressure. My work is centered on the Java and Spring ecosystem, where I bridge the gap between application code and infrastructure reliability.

I am an Oracle Cloud Infrastructure [2025] Certified Developer Professional. This certification reflects my ability to design, build, and deploy cloud-native applications that are both scalable and cost-effective.

I focus on building production-first backends, prioritizing observability, and fault isolation. My implementation style leverages Hibernate for persistence and Kafka for event-driven flows, ensuring data integrity across distributed envs.

My workflow is built around modern DevOps practices using Docker and K8s for container orchestration. I manage the full dev lifecycle from schema design in MySQL/PostgreSQL to automated builds using Maven and GitHub Actions.

Whether deploying on AWS or OCI, my goal is to ensure that the underlying infrastructure remains as resilient as the code it supports.

This commitment to system stability extends to the frameworks I use; as a contributor to Spring Cloud Stream (PR #3186), I’ve worked on optimizing core retry semantics. While I primarily specialize in the JVM, I also utilize Go and GraphQL for specialized high-performance tooling.

I'm constantly exploring the boundaries of robust, scalable systems—specifically where Agentic AI intersects with backend infrastructure. I believe the next generation of architecture isn't just automated; it’s autonomous. My goal is to move beyond static scripts toward self-healing systems that leverage LLMs for real-time operational reasoning and predictive reliability.

I’m always open to discussing backend architecture challenges, debating the trade-offs of modern deployment strategies, or collaborating on high-impact open-source projects. If you're looking for a developer who thinks in terms of systems and survival, let's connect.
