À propos de moi
Senior C++ / Java / MySQL backend engineerI build production backends that serve real users — not tutorial demos.
✔ C++ network programming: TCP/UDP servers, epoll, custom protocols, brpc — chat and IM systems built for high concurrency ✔ Java: Spring Boot microservices, Netty gateways, JWT auth, REST APIs ✔ MySQL: schema design, indexing strategy, slow-query tuning, Redis caching
Every delivery includes documented, maintainable code and a README explaining the design, so you can extend it after delivery.
Message me before ordering — I'll scope your project and pick the right package.
