Launch offer$71920% off for the first 5 clients

Rescue a broken, stalled or AI-generated app

1-2 weeksNon-technical founders whose AI-built or unfinished app works in a demo but breaks with real users, and who need it launched rather than rebuilt.

Where I work from: Rajshahi, Bangladesh · remote worldwide · UTC+6

Your app was built with Lovable, Bolt, v0 or Cursor, or a developer left it half finished, and it does not hold up in front of real users. I find what blocks launch, fix it, and put it on hosting you own.

Fixes, Audits & App Rescue — questions

What this package covers, and how working with me from Bangladesh runs

I'm a freelance AI product developer from Rajshahi, Bangladesh, working under the name Mursalin's Desk. I build AI agent SaaS products, AI-powered mobile apps with React Native and Expo, MVPs for startups, AI integrations for existing products, and full-stack web platforms on Next.js, NestJS and PostgreSQL. I also take on AI strategy and fractional CTO engagements for founders who need senior technical leadership without a full-time hire.

I'm based in Rajshahi, Bangladesh, and also work from Dhaka. Most of my clients are remote — startups and small companies in the US, UK, Canada, Australia and the EU. I can meet in person in Rajshahi or Dhaka when that helps, but every project I run is set up to work fully remotely from day one: shared repo, project board, async updates and scheduled calls.
