Project details
You will get a production-ready Spring Boot microservice with clean architecture, secure REST APIs, and proper documentation. I bring 5+ years of building backend systems for fintech and digital banking, handling real transaction volume, not toy demos. Every service comes Dockerized, with Spring Security setup, database integration, basic JUnit coverage, and API docs (Swagger/Postman) so your team can pick it up without depending on me. Whether you need a service carved out of a monolith or a fresh backend for a new feature, I design around your actual domain, not just a generic CRUD wrapper.

Java Spring Boot Developer for Bug Fix
It was a great experience working with Umar. He quickly understood the issue in our Java Spring Boot application and resolved it efficiently within a very short time. His strong technical knowledge and problem-solving skills were clearly evident throughout the process. Communication was smooth, and he ensured the application remained stable after the fix was implemented. Highly recommended for any Java Spring Boot development work!

Job Success
Islamabad, Pakistan - 3:02 am local time
5+ years building backend systems for fintech and digital banking: REST APIs, Kafka/RabbitMQ event pipelines, and Spring Security-hardened services that handle real transaction volume.
What I typically own end-to-end:
→ Microservices architecture from scratch (domain boundaries, not just code)
→ Monolith → event-driven migrations with zero-downtime cutover
→ API security (OAuth2, Spring Security) for payment and banking flows
→ High-throughput Kafka/RabbitMQ integration
→ Clean handoffs — documentation and JUnit coverage so your team isn't dependent on me
I've built core banking and microfinance platforms (see portfolio) where the architecture had to hold up under real regulatory and load constraints not just pass a code review.
If your backend is the bottleneck slow APIs, tangled services, scaling pain let's talk about what a clean rebuild looks like.

Architecture & Scope Confirmation
I review your requirements, confirm endpoints, database schema, and tech preferences with you before writing any code so we're aligned on scope upfront.
Build, Secure & Test
I build the microservice, set up Spring Security, integrate your database, and write JUnit tests. I'll share progress checkpoints in the workroom as I go.
