Taking new workStart a build

The work, in full

A system is only
as good as the morning
it survives.

Every case study is written the way I would explain it to another engineer: what it is, what was actually hard, and what I decided. The architecture diagram comes first and the screenshots come second, because that is the order the two things matter in.

01ResumeBar/2026

Resume Bar

An AI resume builder that streams its suggestions token by token and renders its PDFs on the server, because the browser could not be trusted with either.

The provider abstraction is the whole point. Bedrock and OpenAI are interchangeable behind it, and PDF rendering was pulled off the client entirely, because a browser you do not control is not a rendering engine.

All 4 systems

What I actually do

Three things, and
the third is the real one.

01

Build

The system itself, from an empty repo to something people log into.

  • Internal tools & ERPsHR, inventory, attendance, operations. The software a business runs on.
  • SaaS productsMulti-tenant apps, billing, editor-style interfaces, real product state.
  • Client portals & dashboardsData-heavy screens that stay fast when the table has 40,000 rows.
  • Marketing sites that performStatic, fast, indexed. Built to be edited by the client afterwards.
02

Automate

Work that a person is currently doing by hand, moved into a pipeline.

  • Workflow automationn8n and custom pipelines. Triggers, retries, and alerts when a run fails.
  • AI in the loopExtraction, classification, drafting, with a human check where it matters.
  • IntegrationsWhatsApp, payment gateways, CRMs, sheets. The unglamorous plumbing.
  • Reporting that leaves the systemScheduled exports, because people still want the sheet.
03

Keep it running

The part nobody puts on a services page, and the only part that decides whether you hire me twice.

  • Deploy & CII replaced zip-file deployments with a GitHub Actions pipeline, and moved a live product off managed hosting onto a self-managed Linux server. Several production apps now run on one 2GB box at 236ms average response.
  • Incident responseFound a live production server with its IP exposed. DNS moved behind Cloudflare, Ubuntu hardened with UFW, Fail2Ban and PAM-secured SSH. Closed in 48 hours, zero downtime.
  • Handover documentationWritten so your next developer does not have to call me.
  • MaintenanceI do not disappear after invoice. Sixteen of my sites are still mine to keep up.

For agencies

Your client never
has to know I exist.

Most of my work reaches the end client with somebody else's logo on it. If you sell AI automation, internal tools or custom software and you do not want the fixed cost of an engineering team, I am the person who builds it and stays invisible.

01Your brand
I ship under your name. No credit, no backlink, no signature in the footer. Your client meets you.
02Your process
Your PM, your standups, your tracker, your repo. I fit into how you already run projects.
03NDA by default
Signed before the first call if you want it. Nothing I build for you appears on this site without written sign-off.
04Fixed scope, fixed price
Quoted per build, agreed before I start. You quote your client with a number that will not move under you.

Not an agency?

You want a site,
not a project.

I keep 16 finished designs running across four trades, four genuinely different directions each, not one theme recoloured. Open them, pick the one you like, and I fit your content to it. Every link below is a live site, not a mockup.
