Frequently asked questions
About Swarnalata
Java Backend Developer | Spring Boot | REST APIs | PostgreSQL | AWS
Sambalpur, India - 7:44 am local time
I'm a Java/Spring Boot backend developer with 2+ years of professional
experience (Wipro) who also independently built, deployed, and maintains
a real e-commerce platform from scratch: Spring Boot + React + MySQL,
running on a Linux VPS with nginx.
This isn't a tutorial project. It has real customers, real orders, and
real production incidents I've had to diagnose and fix myself — including
a recent outage where my hosting provider silently blocked outbound SMTP
ports, breaking all order confirmation emails. I diagnosed the root cause
and migrated the entire email system to an HTTPS-based provider with zero
data loss, while the site stayed live.
What I can help you with:
✅ REST API development (Spring Boot, JWT authentication, Swagger docs)
✅ MySQL/PostgreSQL database design & query optimization
✅ Bug fixes & production debugging — I troubleshoot live systems, not
just code in isolation
✅ Deployment & server setup (VPS, nginx, systemd for auto-restart)
✅ Database migration (Oracle, PostgreSQL, Snowflake)
At Wipro, I worked on enterprise REST APIs for telecom data processing,
including AWS S3 integration and query performance optimization.
I respond fast, explain what I'm doing in plain language, and treat your
project the same way I treat my own production app — like it actually
needs to work, not just compile.
Message me with your issue or project details — happy to give an honest
read on scope before you hire.
