What I'm looking for

I’m looking for a role where I can build scalable, secure Node.js/NestJS APIs with AWS serverless, improve database performance, and own features end-to-end—while collaborating closely with frontend and DevOps to deliver reliable production systems.

I’m a Node.js Backend Developer with 3 years of experience building scalable, secure REST APIs and production-ready services using Node.js, Express.js, and NestJS.

I design and optimize database models and access patterns across PostgreSQL and DynamoDB, strengthening performance through indexing, joins, and clean layered architecture. I also implement secure authentication and authorization using AWS Cognito JWT and RBAC, with reliable logging, error handling, and Swagger/OpenAPI documentation.

On the cloud side, I build serverless backends with AWS Lambda and Serverless Framework, integrating S3 for secure file storage via presigned URLs. I’ve delivered end-to-end modules (e.g., User, Authentication, Admin, Posts, Playlists, and Subscriptions) and support quality by building Cypress-driven test suites for backend-driven and UI flows.
