I build real products with AI

and help founders do the same.

Senior engineer helping non-technical founders ship production-ready products with AI, fast and without the mess.

10+ yrs · 6M+ user app · 50+ apps shipped

Results, not promises

A few numbers from real production work.

  • 3.2 → 4.7

    App Store rating after the rebuild

  • 5.6s → 0.5s

Rebuilding a 6M+ user telco app

Lead engineer · a pan-European telco

I led the rebuild of the flagship app at a pan-European telco with 6M+ users. We moved it to a new platform with zero customer-facing downtime. The App Store rating went from 3.2 to 4.7 and cold start dropped from 5.6s to 0.5s. Along the way I grew mobile from a team of one to 12 engineers. Then I built a Travel eSIM product on my own, from idea to pitch to launch. It reached around 120,000 users in the UK and US within 6 months.

  • Zero downtime
  • 3.2 → 4.7 rating
  • Team of 1 → 12
  • Solo eSIM launch, ~120k users in 6 months

How I think

Three things I believe about building with AI.

  1. 01

    AI makes senior engineers 10x.

    It doesn't turn beginners into seniors. The tools amplify judgement you already have. They don't replace it.

  2. 02

    A solo founder can now ship what used to need a team.

    With the right setup, one person with AI can get a real product to real users.

  3. 03

    The demo is 10%. Production is the other 90%.

    Anyone can generate a demo now. Scale, security, app store review, monitoring, engagement, real users and maintenance are where products live or die.

How I can help

No packages, no pricing page. Tell me where you're stuck and we'll figure out if I'm useful.

  • Figure out what to build

    Turn a rough idea into a clear scope and a first version you can actually launch. What to build first, what to skip, and what will bite you later.

  • Build with AI, properly

    I use Cursor and Claude Code daily on production code. Fast to build, with the architecture, testing and release process that keeps it standing.

  • Rescue an AI-built MVP

    Built something with AI and it's starting to wobble? I'll look under the hood and tell you what's solid, what's risky and what to fix first.

  • Technical sounding board

    Making tech decisions as a non-technical founder? Think of me as the engineer friend you can run things past before you commit time or money.

What clients say

From LinkedIn recommendations and Upwork reviews, where I hold a 100% Job Success score.

I hired Ahsan to help develop a mobile and web app in the health and wellness space. We had a large codebase and quite a lot of legacy code for Ahsan to familiarize himself with. Ahsan was incredibly quick to not only master the code, but also make suggestions for greater efficiencies, fewer packages, and better design, all of which improved our app’s performance and ease of use within the first few months of his hire. Ahsan immediately proved to be a key contributor to the team, not only with his vast knowledge, deep expertise, and reliable work, but also with his clear, kind, and thorough mode of communication. He is a true joy to work with. In short, Ahsan is the ideal team member. He is dedicated, hard working, tackles every challenge and task with friendly and effective gusto, and still has the bandwidth to troubleshoot, problem solve, and improve on aspects of our app that we haven’t even noted. I highly recommend him for any project and any team, big or small. His contributions are invaluable. Thank you, Ahsan!
“Ahsan was a pleasure to work with. Fast, highly communicative, and friendly.”

“Building TwiLix with Ahsan has been an incredibly smooth and rewarding experience. He understood the vision from day one and consistently brought smart ideas, clean execution, and real attention to detail. What really stood out was how much he cared about the project. He treated it like his own, not just another job. Communication was always clear, deadlines were met, and he made even the toughest challenges feel manageable. I'm genuinely thankful to have had Ahsan on this project. He's not just a skilled developer, but someone who adds real value to whatever he works on. I'd happily team up with him again anytime.”

“I worked with Ahsan on a project to implement a new app for [a pan-European telco]. Ahsan is very knowledgeable and professional, he is a clear thinker and great team manager ensuring that activities get delivered within timelines agreed and to a high standard. I really enjoyed working with Ahsan, knowing that he would work through any issues faced, I could trust what he told me and could rely on the timelines agreed. There were a lot of challenges with the project in terms of late, unclear and changing requirements but Ahsan worked with the business to ensure issues were overcome and the project delivered. Ahsan also had many conflicting activities which he navigated his team through to ensure deliveries were correctly prioritised. As a developer, development team manager and technical project manager Ahsan is the best I have worked with and I would absolutely recommend him”
“Ahsan did a solid job. He was one of the best freelancers we had the pleasure of working with on Upwork. He understood what I needed, communicated clearly, and delivered the work without any hassle. Good experience overall and I'd work with him again.”

That skill often takes years to develop among professionals.No matter how tense a meeting, Ahsan make sure everyone to leave with a smile. As a team lead, Ahsan earns my highest recommendation.”
