I'm Haseeb — founder of Bracket Mind and a senior full-stack and AI engineer with 10+ years turning complex business problems into production software. I spent four years as a senior engineer at Contour Software (part of Constellation Software) on enterprise SaaS serving 100K+ users, built BI systems at Bilytica, and now run Bracket Mind — building SaaS and AI products for clients worldwide alongside our own: Aidfolk, live at aidfolk.com, and Zentally, in development.
I build with AI coding agents every day — Claude Code, Cursor, OpenAI Codex and Antigravity — with rule files and project skills in my repositories. On Zentally, our mobile app, non-trivial changes also pass a four-agent review — architect, QA and security reviewers, plus design for UI changes — and tests and CI still decide whether anything ships.
