What I'm looking for

I’m looking to keep building end-to-end web applications—modernizing Angular/Node services, delivering reliable REST APIs, and ensuring quality through testing, debugging, and performance optimization across AWS environments.

I’m a Full-Stack Developer who started as a Junior Java Consultant at TCS, resolving QA-reported defects through reproducing issues, root-cause analysis, and Java SE/Java 8 + Git/GitLab-based implementations. I then transitioned to building full-stack insurance features, creating front-end views with Angular (8–12), TypeScript, RxJS, and SCSS, while building RESTful services with Java 8 + Spring Boot 2.x and optimizing SQL for MySQL.

Since then, I’ve delivered modern web applications across teams and environments—building a complete web-based management platform with React and Node.js (Express 4.x), securing APIs with JWT, and deploying to AWS (EC2, Elastic Beanstalk, S3, CodePipeline). More recently, I’ve extended Node.js APIs, designed serverless AWS Lambda (Python) components, and implemented event-driven workflows with AWS services and Amazon OpenSearch, backed by strong testing with JUnit/Mockito and Jest/Supertest.
