Building

We need something that doesn't exist yet.

No vendor sells the thing you need. An internal tool, a product capability, or a workflow that has to be built around how your business actually works. The fix is to build it: data model, backend, and interface as one system, shipped, and handed over on a repo your team can keep moving on.

The symptoms

You probably recognise a few of these.

  • A spreadsheet has quietly become mission-critical software.
  • The thing you need exists as five disconnected SaaS subscriptions and a lot of glue.
  • A product idea is stuck because no one can build the data layer under it.
  • You need a tool built the way your business runs, not the way a vendor assumed.

What I build
  • Scoped product or internal tool from idea to shipped. Not a prototype that dies in staging.
  • Data model, backend, and front end built as one system. No seams where it matters.
  • AI-assisted reporting or tooling where it earns its keep. Not AI for its own sake.
  • A repo and architecture your team can keep shipping on. You keep moving after I leave.
Capabilities

The specific, findable things I do inside this. Open one for detail.

Internal tools built around how the business actually runs

Software shaped to your workflow, not a workflow bent around someone else's SaaS assumptions. I build the tool your team actually needs when a spreadsheet has quietly become mission-critical software. It fits how you already work, so adoption is not a fight.

  • Next.js
  • Node.js
Scoped product builds from idea to shipped

Scoped product builds taken from idea to shipped on Next.js, Node.js, GCP, and Vercel, from first commit to live. I own the data model, the backend, and the interface as one system, so there are no seams where it matters. You get something in production, not a prototype that dies in staging.

  • Next.js
  • Node.js
  • GCP
  • Vercel
AI-assisted reporting and tooling

AI built in where it earns its keep, not bolted on for its own sake. I use it for the parts where it genuinely beats a deterministic approach, like summarising or triage, and keep it out of the parts where it does not. The result is tooling that is smarter where it counts and predictable everywhere else.

  • OpenAI
  • Cursor
Data models and backends built as one system

The data layer and the application built together as one system, so the model under the product is never an afterthought. Designing the schema and the app in step avoids the glue code and mismatches that slow later changes. It keeps the thing fast to build on after launch.

  • BigQuery
  • Node.js
Analytics auditing tools

Purpose-built analytics auditing tools, like a live auditor validated against DevTools and running on a client site. It catches tracking that breaks silently on deploys, the kind of failure no off-the-shelf tool flagged the way this client needed. The team owns the tool and the confidence that their data is still firing correctly.

  • Node.js
  • GCP
How this kind of engagement runs

Scope the build against how the business actually works, design the data model and system together, ship it, then hand over a repo your team can keep moving on. Project or retainer. You work directly with me.

Internal tooling

A live analytics auditing tool

The problem

Tracking broke silently on deploys and nobody knew until a report looked wrong. No off-the-shelf tool caught it the way this client needed.

What I built

I built a front-end analytics auditor in Node.js on GCP with AI-assisted reporting, running live on the client's site and validated against DevTools, not just "it fires."

The result

Breakages surfaced the moment they happened, on a tool the team owns.

Livevalidated vs DevTools
