What I'm looking for

I’m looking for a role where I can lead backend architecture for scalable fintech systems, own event-driven microservices, and collaborate with teams that value observability, cloud-native engineering, and AI-assisted developer productivity.

I’m a Senior Software Engineer, Tech Lead, and Software Architect specialized in scalable backend systems for fintech infrastructure. I focus on cloud-native, NoSQL-ready designs, distributed systems, and event-driven architectures—backed by a strong Kotlin and Java engineering workflow.

In recent roles, I’ve designed and built backend services for money movement platforms, stablecoin integrations, and high-scale distributed systems. I lead architecture and execution across Java 21/Kotlin, Spring Boot, WebFlux/Reactor, Kafka and AWS messaging, with observability, distributed tracing, auditing, and resilient system design.

I also bring end-to-end delivery strength with cloud-native deployments and CI/CD automation on AWS, including ECS/S3/Aurora/CloudWatch patterns. I support technical leadership through backend architecture decisions, code reviews, engineering best practices, and integration work with banking providers, blockchain infrastructure, and third-party financial APIs.

Earlier in my career, I worked as a Full Stack Engineer / Architect and DevOps-oriented leader, delivering solutions that connected backend services with modern front-end experiences. I’ve also served as an instructor teaching Java fundamentals and advanced topics (threads, networking, and Hibernate), and I leverage AI-assisted development workflows (Cursor, Claude, Gemini) alongside tools like GitHub Copilot and strong testing/engineering discipline.
