@jeandedieunshimyumuk
Backend developer specialized in scalable microservices and secure payment integrations.
What I'm looking for
I am a motivated backend developer with hands-on experience building scalable microservices, payment integrations, and secure file storage solutions using NestJS, Spring Boot, Docker, and blockchain technologies. I have delivered features like session booking, autonomous task marketplaces, digital repositories, and CI/CD pipelines for clients including Gradpal, Rwanda TVET Board, DHP-Irage, and QuantaLedger.
I collaborate across front-end and back-end teams to ensure cohesive product delivery, optimize performance, and implement robust workflows such as Jenkins pipelines and containerized deployments. I continuously learn and apply modern stacks—microservices, gRPC, Hyperledger Fabric, MinIO, and Stripe—to produce reliable, production-grade systems that meet industry standards.
