I turn business problems into working software.

Need an app built? Or tired of repetitive work eating your team's week? I build it, or automate it with AI, and explain every step in plain English.

  • The Players Fund
  • 248.AI
  • Stellic

Sound familiar?

Founders often get stuck on one of these.

  • I have an idea for an app, but no technical co-founder.

  • I paid for software that never quite worked, or never got finished.

  • My team copies data between spreadsheets and tools all day.

  • I keep hearing about AI, but I can't tell where it would actually help my business.

  • Our product works, but it's slow, fragile, and scary to change.

  • I need one senior person I can trust to own this and explain it without jargon.

If any of these sound like you, let's talk.

How I can help

Two ways I can help your business.

Build my product

Your idea becomes a real, working product your customers can use, built so it can grow without being rebuilt from scratch.

What that can look like

  • A first version (MVP) to test with customers or show investors
  • A customer portal, booking platform, or marketplace
  • An internal dashboard your team relies on every day

Tools I use: Python, FastAPI, Django, PostgreSQL, MongoDB, AWS, Docker

Automate my busywork

The repetitive tasks eating your team's week run themselves, with people stepping in only to make decisions.

What that can look like

  • Reading documents and emails and filling in your systems automatically
  • Enriching, sorting, and scoring leads or applications
  • Keeping your tools and spreadsheets in sync

Tools I use: AI language models (LLMs), Python, cloud services, CI/CD

How it works

Simple, clear, and no surprises.

  1. A free intro call

    We talk about what you're trying to achieve. No jargon, no hard sell, no obligation.

  2. A clear plan in writing

    You get what I'd build, how long I expect it to take, and what it costs, before you commit to anything.

  3. Built in small, visible steps

    You see working progress every week and can change direction early, not after the money is spent.

Who you'll work with

Hi, I'm Hasnain.

I'm a software engineer with over ten years of experience helping founders and teams turn rough ideas into dependable software. I've worked with teams across several countries, from a Y Combinator-backed startup to an investment platform, and I'm used to translating between what the business needs and what the technology can do.

My approach is simple: move quickly without creating a mess you'll pay to clean up later. You get plain-English updates, honest advice (including "you don't need this yet"), and software the next developer can pick up easily.

Questions

Questions you might have.

Do I need to be technical?

No. I explain everything in plain English, and I ask about your business first and the technology second.

How much does it cost?

It depends on what you need, so I don't quote blind. After our call I send a written scope and a clear estimate, so you know the cost before committing to anything.

How long does it take?

Small, focused projects move quickly; bigger ones take longer. The written plan after our call includes a timeline, and you see working progress along the way.

What if I don't know exactly what I need?

That's a perfectly good starting point. The intro call is for working it out together, and sometimes the answer is a simple fix rather than a big build.
