Java springboot Expert
Abel did a great job on our Java Spring Boot project. He fixed a critical memory issue, resolved PostgreSQL migration problems, and improved overall backend stability. He also worked on WhatsApp integration using Meta (Facebook) APIs, secured communication with our PHP/Laravel APIs, and added proper protection against bot attacks. Communication was smooth and he handled production issues confidently. I would be happy to work with him again.

Web App Development with Spring Boot
Abel did an excellent job with our API integration project. He quickly understood the requirements, set up a clean and efficient integration, and communicated clearly throughout the process. The work was delivered on time, and any technical questions I had were explained in a simple and professional way. I really appreciate his attention to detail and problem-solving skills. Highly recommended for any backend or API-related work!

Job Success
Addis Ababa, EthiopiaĀ - 5:38 pm local time
I'm Abel Adisu, a Senior Java Backend Engineer with 3+ years of professional experience building enterprise-grade microservices, secure APIs, and distributed systems for government institutions and financial organizations. My systems don't just pass unit tests ā they operate under real institutional pressure, processing real government revenue and managing real court cases affecting real people.
I specialize in Java Spring Boot microservices architecture, Keycloak OAuth2 security, Apache Kafka event-driven systems, Camunda BPM workflow automation, and cloud-native DevOps with Docker and Kubernetes.
FLAGSHIP PROJECTS

āļø Amhara Region Integrated Court Management System
Architected a Camunda BPM workflow platform that digitally connects Police ā Prosecutors ā Corrections ā Courts across an entire region ā eliminating manual case handling and dramatically reducing processing time. Technologies: Camunda BPM, Spring Boot Microservices, React, Docker.
š¦ Banking & USSD Backend Systems

I don't take tickets and disappear. I own the backend ā spotting architecture risks before they become production incidents, communicating clearly across time zones, and delivering systems that still run clean six months after handoff.
If your project involves real users, real transactions, or real consequences ā let's talk.
