Message

At DevsFleet, I develop and maintain production-ready web applications and backend services based on business and client requirements. I design RESTful APIs, authentication workflows, and database integrations.

At AitchTech, I built and enhanced full-stack web applications across frontend, backend, database, and API integration layers. I designed schemas and optimized queries for PostgreSQL and MongoDB applications.

Earlier, I developed backend services and REST APIs at BEDM (Private) Limited, then supported web application development at Cubix Hub. My work included authentication, external service integrations, debugging, and production improvements.
