about
Mamun Ahmed
Full-Stack Web Application Developer & Software Founder
I build the operational software businesses run on: CRM and case-management systems, education and learning platforms, multi-branch retail and point of sale, payments, and the automation that removes the manual steps between them.
The work I take on tends to have three things in common. It holds real money or real people's data, so correctness matters more than novelty. It is used every working day, so it has to be deployed without downtime and maintained for years. And it is rarely a blank page — most of it means understanding a business that already works, in spreadsheets and inboxes, and building the system that finally fits it.
I work end to end: data model, backend, interface, deployment and the ongoing changes afterwards. On most of the projects in my portfolio I am the only developer, which means the architecture has to be something a single person can still reason about a year later.
01how i work
Four things I actually do
01
Inspect before changing
Before touching a system I read it: the data model, the deployment, what the last person was solving. Most bad changes come from confident assumptions about code nobody re-read.
02
Business logic before UI
A screen that looks right over a model that is wrong is a liability. I get the entities, the states and the money definitions right first; the interface follows from them.
03
Verification before "done"
A green local build is not evidence. I check the deployed thing — the page served, the row written, the email received — before saying a change is shipped.
04
Build for maintainability
The architecture has to still make sense after a year of changes made in a hurry. Invariants that matter get enforced by the database or by a test that fails the build, not by discipline.
02experience
Where the work has been
Most of my projects are named in the case studies: an education operations platform handling student applications, agents and commission; a multi-branch retail platform with a storefront, point of sale and warehouse working from one catalogue; a CPD learning platform with secure lesson delivery and verifiable certificates; a property and investment CRM with its authorisation enforced in the database; and a case-management system for a regulated advisory practice, described without naming the client because of what it holds.
Two of those are sanitised on this site. That is deliberate: if a system holds sensitive data, the case study describes the engineering and leaves the client unnamed. I would rather lose the logo than be careless with it.
Before the application work there were marketing and brochure sites — they are listed in the archive at the bottom of the work page. They are where I learned to ship, and they are not what I do now.

04the company
Founder of AM IT Solution
I founded AM IT Solution to build custom software for businesses whose operations have outgrown spreadsheets, disconnected tools and manual processes. It is UK-registered and bills in pounds, and it works with clients internationally.
This site is mine: my work, my writing, how I think about building systems. The company site is where the company sells. Keeping them separate is the point.

Around the work
I am part of the Programming Hero developer community — alumni meetups and the HeroUnion gatherings, where a few hundred developers compare what they are building.

Questions people ask first
- Who is Mamun Ahmed?
- Mamun Ahmed is a full-stack web application developer based in the United Kingdom and the founder of AM IT Solution. He designs and builds the operational software businesses run on — CRM and case-management systems, education and learning platforms, multi-branch retail and point of sale, payments and business automation — usually as the sole developer, from data model through to deployment and ongoing maintenance.
- What does Mamun Ahmed build?
- He builds production web applications rather than marketing sites: custom business systems, SaaS platforms, CRM and internal tools, education and learning platforms, e-commerce with point of sale and inventory, payment integrations, and the automation and APIs that connect them. The work is characterised by holding real money or personal data, being used daily, and replacing a process that currently runs on spreadsheets and shared inboxes.
- What is AM IT Solution?
- AM IT Solution is the custom software company Mamun Ahmed founded. It is UK-registered, bills in pounds and works with clients internationally, building operational systems for businesses whose processes have outgrown spreadsheets, disconnected tools and manual work. Larger engagements are delivered through the company; webdmamun.com is Mamun’s own portfolio and writing.
- What technologies does Mamun Ahmed use?
- Next.js, React and TypeScript on the frontend; Node.js, Laravel and PHP on the backend; PostgreSQL with Drizzle or Prisma, and Supabase, for data; Vercel, Oracle Cloud, Linux, Nginx and Docker for infrastructure; Stripe, Cloudflare R2, Resend and Sentry as services; and Playwright, Vitest and Jest for testing. He lists only technologies he has shipped with and is comfortable being questioned about.
- What kinds of businesses does he work with?
- Education consultancies and training providers, legal and immigration advisory practices, property and investment businesses, and multi-branch retail and e-commerce operators. These are businesses large enough to have a real process and small enough that no off-the-shelf product fits it.
- How do you hire Mamun Ahmed?
- Through the contact form at webdmamun.com/contact or by emailing hello@webdmamun.com. The useful first message describes how the business works today and which process is costing the most time; he replies personally, usually within one working day.
