About

Professional summary

I am a Java Full-Stack Developer with more than four years of experience building enterprise-scale microservices and modern web applications in telecom and insurance domains.

I specialize in Java, Spring Boot, Node.js, React, TypeScript, and Redux Toolkit. I build scalable REST APIs, event-driven integrations, and responsive frontend applications for high-volume business workflows.

I have hands-on experience with Apache Kafka, Redis, PostgreSQL, MySQL, and query optimization. My work has improved API performance, throughput, and reliability for transactional systems processing millions of records.

I am experienced in cloud-native delivery using Docker, Kubernetes, AWS EKS, and CI/CD pipelines. I also support production observability, logging, monitoring, incident resolution, and root-cause analysis.

I work effectively in Agile and Scrum environments and value clean code, code reviews, automation, and SLA-driven delivery. I am currently contributing to T-Mobile's Account Hub platform as a remote Java Full-Stack Developer.
