React Native development for companies

I help product teams plan, build and improve production React Native apps, from a focused MVP to an app with millions of users.

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

How I can help your team

Pick the shape that fits. Most engagements mix a couple of these.

  • Own a workstream

    Hand me a defined piece of the product: a new feature area, a rebuild or a new app. I take it from scope to store release and keep you updated every week.

  • Lead or support your mobile team

    Join as a senior or lead engineer. Architecture, code review, release process and unblocking people, while still writing a lot of the code.

  • Audit and improve

    I review the codebase, performance, crash rate and release process, rank what to fix by impact, and help your team fix it.

  • Train your team

    Practical React Native training built around your own codebase: New Architecture, testing, performance and working well with AI tools.

Proven at scale

I led the rebuild of the flagship app at a pan-European telco, then launched a Travel eSIM product on my own that reached around 120,000 users in 6 months.

  • 6M+

    customers on the telco app I led the rebuild of

  • 3.2 → 4.7

How we'd work together

  1. 01

    Intro call

    We talk through the product, the team and what's in the way. If I'm not the right fit, I'll say so.

  2. 02

    Assessment

    I look at the code and the roadmap, then write up a plan with scope, risks and what to do first.

  3. 03

    Build

    Work lands in your repo through your process: pull requests, code review, regular demos and clear status.

  4. 04

    Handover

    Tests, docs and a team that understands what was built, so nothing depends on me staying.

What you can expect

  • Test-driven development and end-to-end tests on critical journeys
  • Design systems with primitive, semantic and component tokens
  • Release strategy, feature flags and phased rollouts
  • CI/CD with Fastlane and GitHub Actions
  • Monitoring, alerting and crash tracking
  • Performance work, including the New Architecture
  • Native modules in Swift and Kotlin when React Native isn't enough
  • Agreeing scope, trade-offs and timelines with stakeholders

What teams say

“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 is a person you always want to have in your team. He is calm, painstaking with a positive attitude. You just need to assign him a task and leave everything on him. He will complete the task with full ownership, within a timeline, with every aspect of the task properly implemented, thoroughly tested. He is always ready to go beyond his duty to fulfill the team or even the organization goals. A very good team player with a friendly nature. I highly recommend him for any position he wants to have.”
“I rarely come across real talents who stand out like Ahsan. I had the pleasure of working with Ahsan at Tkxel, collaborating on several projects. I was impressed by Ahsan’s ability to deal with even the toughest clients – effortlessly. 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.”
