About Abhishek

I’m a Full-Stack Developer (MERN) and Backend Engineer (Java Spring Boot) who builds scalable web apps, secure APIs, and automation-focused AI agents. I work comfortably with any database (SQL/NoSQL) and also use Python libraries for AI/ML workflows and data processing.
My focus is on clean architecture, performance, and production-ready delivery.

What I can help you with:

- MERN apps (React UI + Node/Express backend)
- Spring Boot backend APIs (JWT auth, RBAC, microservices-ready)
- Database design & optimization (MongoDB, MySQL, PostgreSQL, etc.)
- Integrations (payment, email, third-party APIs)
- AI agents (RAG, tool/function calling, workflow automation)
- Bug fixing, performance improvements, deployment support
