Jaydip Koriya

I’m a Full Stack Developer with 1+ year of hands-on experience across the complete development lifecycle—designing APIs, building services, and delivering interfaces. I’m passionate about product engineering, clean architecture, and writing code that scales with the business.

At eSparkBiz Pvt. Ltd., I engineered full stack production features across a microservices architecture using NestJS, React, and PostgreSQL. I designed and deployed secure RESTful APIs with JWT-based authentication and role-based authorization, reducing unauthorized access incidents and improving backend security compliance.

I also refactored backend modules into reusable NestJS services following clean architecture principles, cutting average feature development time by 30%. To strengthen integrity and auditability, I implemented immutable data storage for authentication and verification records, and improved scalability with modular service design and reusable React components—helping the team onboard new features 2x faster with reduced regression risk.
