I.The developer
Shahbaz Ansari. Full-stack developer working remotely with clients around the world.
II.The practice
Web and mobile apps, AI tools and websites, plus the care that keeps them running after launch.
III.The way I work
No meetings. Everything happens in writing, and I take on a few projects at a time.
IFree tools
Alongside my work building web and mobile products for clients, I create free tools anyone can use. Here are a few to try.
Everything about a domain: registration and expiry, DNS, hosting, email, certificate and the services it uses.
What any website is built with: framework, CMS, hosting, analytics, payments and more, with the evidence for each.
How your link looks when shared on X, LinkedIn, Facebook, WhatsApp, Slack and Discord, and what to fix.
IIThe practice
New products, existing codebases, or ongoing development. I build, extend and maintain software for founders and teams.

iOS and Android apps, built in React Native or turned from your web app with Capacitor. Real native apps, not a website in a wrapper, and I handle the App Store and Play Store release too.
One codebase for iOS and Android · Native device features where your app needs them · Store listings, review and release
Telegram bots and mini apps, from the user experience to the backend. Connect services, automate workflows and bring your product into the apps people already use.

IIIHow it goes
You send a short brief. I reply in writing with questions, then a clear scope and a fixed quote.
Wireframes and a technical plan before any code, so we agree on what we're building.
Weekly written updates and a live preview link, plus a short screen recording when a demo helps.
Deployment, handover and documentation, plus an optional care plan to keep things running.
