Software DeveloperFounder, Crefix AI
Hi, I'm Mahmud Sakib
Full-stack engineer (React, Next, Node, Postgres) building intuitive, reliable web apps. My background in US banking due-diligence and UK healthcare compliance brings forensic precision to your data, processes, and code. I now put all three to work as founder of Crefix AI, a remote ops-and-software team helping UK businesses execute faster.
About Me
I completed my schooling under the Cambridge Board and earned my Bachelor of Science in Computer Science & Engineering (CSE) from North South University. My academic journey gave me a strong foundation in algorithms, data structures, and software architecture.
My career bridges engineering with analysis and operations — building full-stack SaaS products as a Software Developer, running due-diligence analysis for US banks, and managing compliance for UK healthcare clients. Different roles, same habit: careful, methodical work that holds up under scrutiny.
That combination is now the foundation of Crefix AI, a company I founded and lead as CEO. We're a Bangladesh-based remote team helping UK businesses handle operations, software development, QA, and digital marketing through AI-assisted workflows — trading slow, manual outsourcing for faster, transparent execution.
