Mohammad Jubair

I'm Jubair, a Full Stack Software Engineer based in Bangladesh, building scalable software and AI-powered digital solutions.

My work runs on two tracks. As an engineer, I architect and build systems end-to-end - backend services in Node.js and NestJS, frontend interfaces in React and Next.js, database design across PostgreSQL, MySQL and MongoDB, third-party integrations, and cloud deployment infrastructure. I build AI directly into the products themselves, using LLMs and prompt engineering to create features that actually change how a workflow works, not AI bolted on as an afterthought.

As a founder, I've built and shipped two SaaS platforms of my own from the ground up as the sole engineer. Klozio is a lead-generation automation platform that discovers, enriches, and scores prospects, backed by a queue-driven architecture handling high-volume data processing asynchronously, with subscription billing built in. Clozey is an AI-powered platform that generates live, tailored client proposals in real time and centralizes outreach, invoicing, and e-signatures into a single workflow. I owned every layer myself: architecture, database schema, backend logic, frontend, and deployment.

Alongside that, I contribute to full-stack software engineering and AI feature implementation at CodeFusionAI, working directly with international clients and cross-functional teams on production systems, and I co-founded Codex Devware, where I've led technical direction and product architecture alongside business growth strategy.

I'm currently pursuing a B.Sc. in Computer Science & Engineering at East Delta University, building on a diploma in Computer Engineering from Chattogram Polytechnic Institute.

I'm drawn to the intersection of engineering and business - building technology that doesn't just work well technically, but actually moves a product or a company forward. More of what I've built: mohammad-jubair.com
