I will develop scalable java spring boot rest api backend for your app

I build backend systems in Java and Spring Boot.

I have 3.5 years of experience as a backend engineer in Indian fintech, working on payments, customer onboarding, KYC, and bank integrations. The systems I work on handle real money and real users, so I care about correctness, error handling, and code that someone else can maintain.

What I can build for you:

- REST APIs with Spring Boot 3 and Java 21

- Database design and integration (MySQL, MariaDB, PostgreSQL)

- Authentication and role-based access with JWT

- Redis caching and performance tuning

- Kafka and message queue integration

- Third-party and payment API integration

- AWS deployment (EKS, SQS, SNS)

How I work:

I ask questions before writing code. If your requirements have gaps, I will tell you instead of guessing. You get clean, documented source code and a short walkthrough of how it works.

Message me before ordering so we can confirm scope. I will tell you honestly if your project is not a good fit for me.
