Hamidul I.

Software Architect | Distributed Systems | High Performance Backend | Go Centric + AI Systems I design and build production grade backend systems and SaaS platforms with a focus on scalability, fault tolerance, and performance. My core stack is Go for services and infrastructure. I complement it with SQL for data systems, TypeScript and JavaScript for frontend or edge, Flutter for mobile, and Rust for performance critical or low level components when needed. In addition, I design and integrate AI driven systems such as LLM based agents, automation pipelines, and MCP style tool integrations directly into backend architectures. These systems are built to be reliable, observable, and production ready rather than experimental prototypes. I work at the system level by defining service boundaries, designing data flow, controlling concurrency, and building infrastructure aware services that remain stable under real production load.
