About
I’m a Senior Full Stack Engineer with 10+ years of experience building scalable, cloud-native Java applications and modern front-end interfaces. I design distributed microservices with Spring Boot and deploy on AWS and Azure, using Docker and Kubernetes for containerization and orchestration. I also craft responsive UIs with React.js, Next.js, and Angular, and integrate them with REST and GraphQL APIs. I have hands-on experience with event-driven systems (Kafka, Kinesis, RabbitMQ) and robust CI/CD pipelines.
I love applying infrastructure as code with Terraform and CloudFormation, and I explore AI-assisted development tools like GitHub Copilot and Cursor AI to boost productivity while maintaining TDD and automated testing. I enjoy mentoring teammates, guiding cross-functional squads, and delivering reliable software that scales under load across e-commerce and healthcare domains.
