Hire the Best Java Developers
in Ethiopia

If your backend fails in production, it's not a code problem — it's an architecture problem. I build Java Spring Boot systems that handle real traffic, real security threats, and real scale. 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 — 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 🏛️ Ministry of Revenue Backend System Built and maintained a large-scale backend that automates national tax payment, compliance tracking, and revenue operations for the Ethiopian government.

Senior Backend & AI Engineer with 5+ years owning high-throughput, event-driven systems across fintech, research, and AI infrastructure. I design and ship production AI systems: multi-tenant LLM gateways (LiteLLM) routing across Bedrock/OpenAI/Azure, agent orchestration with LangGraph and Postgres-backed checkpointing, and MCP (Model Context Protocol) integrations connecting AI assistants to backend tools securely. Beyond AI, I bring deep backend fundamentals: real-money fintech systems (banking integrations, payment gateways, auditable ledgers), high-scale messaging (500K+ daily SMS/events), and RAG/document pipelines (ingestion, OCR, vector search) built for reliability and auditability at production scale. Technical Stack: Python, TypeScript, FastAPI, NestJS, Java/Spring Boot, LangChain/LangGraph, PostgreSQL/pgvector, AWS (ECS, Fargate, RDS), Docker, Kubernetes, Terraform, Kafka/SQS/RabbitMQ, Prometheus/Grafana. If you need someone who can own both the AI layer and the backend infrastructure it runs on end-to-end, secure, and production-grade, let's connect.

Java Developer and backend engineer specializing in Spring Boot, REST API development, and AI integration — building production-grade systems that solve real business problems, not just pass code review. I am a Java developer with hands-on experience delivering full backend systems independently — from architecture through deployment. Every system I ship is production-ready, properly secured, and documented. What I deliver as your Java developer: ▸ Spring Boot REST APIs — Java backend systems with 60+ endpoints, multi-role JWT security, Redis caching, and WebSocket real-time features. Clean layered architecture, JUnit 5 tested, OpenAPI documented. Built for teams to maintain, not just for demos. ▸ AI Integration — Java developer with Spring AI and OpenAI GPT integration experience. My project Famlytica AI is a 13-module Spring Boot platform with cross-module AI context architecture — awarded 2nd place at a national competition evaluated by PhD faculty with a cash prize. ▸ Machine Learning — IBM-certified Java developer with Python ML skills. I clean, analyze, visualize, and train models with Scikit-learn. Deployed a live ML-powered business intelligence dashboard processing 128,000+ real transactions. ▸ Payment Systems — Java backend developer with full Chapa payment lifecycle integration including HMAC-SHA256 webhook verification and real production money flows. Built for security, not just happy-path demos. ▸ Full-Stack Delivery — Java developer who can build React 19 frontends when your project needs end-to-end delivery, not just a backend handed off to another team. I run a live e-commerce platform (habeshamarket.store) and have delivered backend systems actively used by real businesses. I respond within a few hours and deliver what I commit to.
