I've built backend architecture at 6th Base supporting 50k+ concurrent users across mobile, web, and desktop platforms. My work spans distributed systems, real-time communication, persistence, integrations, and cost-efficient infrastructure.
Using Java, TypeScript, Node.js, Redis, MongoDB, MySQL, and WebSockets, I've delivered progression systems, business logic, data persistence, and high-concurrency messaging. I've also integrated authentication, currency handling, and in-app purchases alongside internal currency systems.
I've set up CI/CD with Cloud Build, automated Linux deployments, and improved server reliability and operating costs. As a Top Rated Upwork developer, I shipped more than 10 projects and earned repeat contracts.
I also contributed to a real-time collaboration platform with chat, streaming, and AI assistants, and created RankDrop, an open-source ranking microservice with progressive scaling architecture and no running costs.
