Senior full-stack developer for businesses that run on their software

Software your business can run on.

Built, shipped, and supported. I turn complicated workflows into usable software, and I stay for the edge cases that show up after launch.

What I build

Four kinds of problems account for most of the work I take on. If yours is close to one of them, it is probably a fit.

Your quoting or ordering process lives in spreadsheets and email.

Business applications & integrations

Quoting systems, dealer and customer portals, document generation, workflow automation, and CRM and CAD integrations that fit how your team already works.

Your WordPress site matters to the business, but nobody owns it.

Custom WordPress development

PHP customization, WooCommerce, ACF, migrations, portal repairs, and ongoing maintenance on sites that already have customers on them.

You have a product idea and need it built to last.

SaaS product development

React and Next.js applications with Supabase authentication, Stripe billing, and AI-enabled workflows.

Something in production is broken and nobody can find it.

Debugging live systems

Race conditions, failed registrations after security updates, hosting transitions, and performance and security review on sites people are using right now.

Quoting, Dealer Portal & CAD Workflows

Euro-Wall

A door and window manufacturer whose quoting, bills of materials, dealer workflows, and CAD operations all run on one internal platform.

Integrated the PHP bill-of-materials engine with an external 3D configurator, with request tracking, webhooks, polling, and logging. Resolved race conditions in the quote editor.

Dealers quote complex products and see 3D previews from the same data that drives manufacturing.

How it goes

From first message to software in use.

  1. 01

    Tell me what it needs to do

    Where the current process gets stuck, who uses it, and what a good result looks like. A few paragraphs in the form is enough to start.

  2. 02

    A first milestone, not a brochure

    I come back with what gets built first, what it takes, and what you will be able to do when it is done. Small enough to judge quickly.

  3. 03

    Build, ship, show

    Working software in your hands early, so you see it in use instead of in slides, and we adjust while changes are still cheap.

  4. 04

    Support after launch

    The edge cases that only show up once real people use it are part of the job, not a new project.
