I build B2B tools for developers and marketers.

Screenshotline, a screenshot API that survives production, and AdLib, which makes Meta's Ad Library usable. Built and run on my own — on top of six more products already shipped through real app-store review.

Tools people use at work

Two B2B tools, each aimed at one job a professional does every week that the obvious tools make painful. Small, sharp, and built and run by one person.

Straight answer before you ask: these are young products, and none of them makes a living yet — Screenshotline is the newest and takes its first customers this month. What they prove is not that I can market. It is that I finish things, get them past review and into production, and keep them running. That is the part your project needs.

How I work

The real risk is someone disappearing at 60%

It is why most people hesitate, and nobody says it out loud. So here is how I take it off the table.

You describe it

A paragraph is enough. What it should do, who it is for. I will tell you honestly if I am the wrong person — that answer costs you a day instead of a month.

Fixed scope, fixed price

Within 48 hours you get written scope and a fixed number, not an hourly estimate that grows. If the scope changes later, we agree the change before it gets built.

A build you can run, weekly

Every week you get something installable, not a progress report. You see the real thing early enough to change your mind while changing it is still cheap.

What I do

Four things, each one already shipped

Every line below names the published product that proves it. That is the whole point of the list.

Mobile apps, idea to store

Flutter for Android and iOS. Design, build, listing, privacy policy, data-safety declaration, submission and the review back-and-forth — the whole way to published, not just to a build file.

Windows desktop software

Internal tools and business software that runs offline on a real machine in a real office. Installers, updates, and Microsoft Store publishing if you want it there.

→ CuePaste · gym management system

APIs, extensions and developer tools

Web APIs that hold up under real traffic, and Chrome MV3 extensions for workflows the browser makes painful — including the awkward parts: billing, abuse limits, content-script isolation, store policy.

→ Screenshotline (screenshot API) · AdLib (Chrome extension)

AI features inside your product

LLM logic built into something that already exists — categorisation, extraction, chat, summarisation. Scoped so it fails visibly instead of confidently making things up.

About

Most software never gets published. Mine does.

I am Mohammed Abdul Mubeen Khan, a solo developer working from India.

The distance between a working prototype and something a stranger can download is where most projects quietly die. Privacy policies, data-safety forms, permission justifications, trader verification, rejections that arrive with no explanation. I have crossed that distance on Google Play, the Microsoft Store and the Chrome Web Store, and I know what each of them asks for before it asks.

Lately that has meant tools for people at work: Screenshotline for developers who need screenshots of the web without running headless Chrome themselves, and AdLib for marketers who need Meta's Ad Library to be usable. Narrow tools, done properly, run by the person who built them.

I work fast, and AI tooling is a large part of how — but I read everything that ships, because the person who has to fix it in month six is me. Speed is not the pitch. Finishing is.
