Engineer.Founder.Builder.
I'm Rufsan — a senior full-stack developer and agency founder building intelligent SaaS products for the US market.
About Me
I specialize in turning complex business ideas into production-ready software at the intersection of AI/ML, full-stack development, and data science.
Over 5+ years and 40+ projects, I've built everything from multi-tenant SaaS platforms generating $2M+ ARR to AI-powered QA tools that cut testing cycles by 60%.
My approach is domain-first: model the business before writing code, work backwards from the end goal, treat security and performance as non-negotiable.
Based in Dhaka, working primarily with US-market clients building commercially viable products.
Values
What drives how I work.
Craft Over Speed

Business First
Code exists to solve business problems. I think in outcomes, not features.
Continuous Learning
AI, ML, and the stack evolve daily. I stay current so my clients stay ahead.
