What I'm looking for

I’m looking to build reliable, high-performance backend systems with clean architecture—shipping scalable Java services, reactive APIs, and event-driven microservices on AWS, with room to grow while collaborating with engineers who value maintainability.

I’m a software engineer focused on designing and building scalable Java backend services and APIs, using Spring Boot, WebFlux, and Kafka. I care deeply about clean architecture, performance, and reliability—especially in distributed, high-concurrency environments.

In my most recent role as a Senior Software Developer, I designed and implemented a remediation microservice with Spring Batch inside a microservices architecture. I streamlined error remediation by automating fixes for common issues and scheduling manual remediation tasks, while also building secure REST APIs to support key banking functions.

I’ve also developed and maintained reactive services with Spring WebFlux to handle high-concurrency workloads and improve system responsiveness. Alongside that, I built event-driven capabilities with Kafka producers/consumers, webhooks, and AWS Lambda for real-time communication across distributed systems, and delivered GraphQL and REST APIs for efficient data querying.

I’m AWS Certified (Developer – Associate) and comfortable working across SQL/NoSQL databases and cloud-native deployments using Docker and Kubernetes. I continue expanding my backend expertise through personal projects in Golang, and I enjoy mentoring and guiding developers to accelerate onboarding.
