Shipped Proof

Case studies that answer the real question: can this person ship serious work?

The strongest signal for UK and US buyers is shipped work, not freelancer slogans. These projects show what was built, why the architecture mattered, and what changed after launch.

Trust Layer

What serious buyers usually check before sending a brief

If you are comparing this against a typical agency process, the difference is direct technical ownership. You speak to the person designing the system, writing the code, and carrying delivery responsibility through launch.

That means faster iteration, earlier risk callouts, cleaner handover, and less management overhead for your team.

UK overlap hours

Available for UK overlap most weekdays, with partial US East overlap scheduled around project milestones.

Payments

Stripe, Wise, and international invoice workflows can be supported for cross-border projects.

NDA-friendly

Happy to work under NDA before detailed technical discussions or codebase access.

GitHub visibility

Public GitHub activity and technical proof are available for founders who want to inspect how the work is approached.

What changed after launch

Need a technical partner you can trust with a serious project?

Send a brief, rough scope, or even a messy problem statement. I will reply directly within 24 hours with next steps, fit assessment, and whether an NDA or discovery call makes sense first.

Questions serious clients usually ask

Direct answers before you decide whether to send a scope or schedule a call.

What kind of work are you best suited for?

The best fit is serious product work: SaaS builds, B2B platforms, internal tools, custom web applications, and legacy systems that need senior engineering ownership.

Do you work directly with UK and US teams?

Yes. Delivery is remote-first with UK overlap most weekdays, partial US overlap when needed, and clear async communication between calls.

Can you join an existing product team instead of starting from zero?

Yes. I can take ownership of a scoped build, modernise an existing codebase, or work as an ongoing technical partner inside an existing delivery flow.

Do you support NDAs and international billing?

Yes. NDA-first conversations are fine, and cross-border projects can be structured with Stripe, Wise, or invoice-based billing.
