Hi ! I'm Umar. A full-stack developer
specialising in ecommerce and integrations.

I build the integration layer between product systems and storefronts, including BigCommerce, Shopify and WooCommerce, at AB Web Developers in Perth. Plus three products I designed, built and shipped on my own.

Commercial products
that I have worked on.

Three commercial products. What each one is, and the part I owned: storefront work at AB Web, and support on Healthengine's live booking platform.

I was a developer
before the agents.

That is still the useful part. I know what good code looks like without a model, so I can tell when one is helping and when it is guessing. Claude Code, Codex and Cursor accelerate the work. I still decide what ships.

Experience

Selected roles, most recent first. The full history is in my résumé: a .NET and AWS internship, a short support role at a healthcare platform, then commerce systems.

  1. Present

    AB Web Developers

    Full Stack Developer

    Commerce integration and platform work across a group of promotional-products storefronts.

    What I shipped Built product export and storefront integrations across BigCommerce, Shopify, and WooCommerce, with catalogue workflows covering 80,000+ products.

  2. Healthengine

    Web Support

    Frontline technical support for a healthcare appointment platform.

    What I shipped Maintained a 10/10 NPS while diagnosing appointment connector and remote-connectivity issues across phone, chat, and ticket queues.

  3. Cloudcon

    Software Developer Intern

    Mobile, web, and backend application work across a .NET and AWS stack.

    What I shipped Delivered React Native app work for Android and iOS alongside ASP.NET/C# services using AWS Lambda, ECS Fargate, KMS, and S3.

I like owning
the whole problem.

I sit where product judgment and engineering meet. Right now that’s commerce integrations and multi-tenant AI services, built end to end.

I learned the long way: reading a codebase, writing the code, reviewing it line by line. A lot of that runs through agents now, and the judgment hasn’t changed. How I work with Claude Code, Codex and Cursor.

  • Own the whole problem

    Workflow, interface, and the system behind it — including the strange edge cases nobody scoped.

  • Build for the week after launch

    Retries, partial writes, honest failure states, and getting unstuck without emailing support.

  • Ship with agents, keep the judgment

    Briefs, skills, MCP, and hooks that refuse the dangerous parts. I still decide what good looks like.

Tell me what
you are building.

Best if you already know the problem: an integration that keeps drifting, a service that needs tenancy before it can be sold, a product that needs building end to end. Perth, Western Australia, and I reply within a day or two.
