Operational results for UK businesses, and a portfolio of technical AI and software builds.
Invoice processing was taking one member of staff the better part of a Friday every week — manual data entry from supplier PDFs into their accounting system.
An automated pipeline that reads incoming invoice PDFs, extracts the relevant fields, and pushes them directly into their accounting system for review. Built and live in six weeks.

Weekly invoice processing time
"We knew we were wasting time on invoices. We didn't know how much until they showed us."
Client reports took two to three hours each to produce — pulling data from multiple platforms, writing commentary, formatting everything to brand. The team was doing it for fifteen clients a month.
An AI-assisted first-draft system that pulls performance data, generates structured commentary, and outputs a formatted report ready for an account manager to review and personalise. The team now handles 40% more clients.
60% faster
Report production time, per client
New client onboarding required staff to manually extract and re-enter information from identity documents, bank statements, and company filings — a process that took up to three days per client.
An automated document processing workflow that extracts, validates, and populates client records from uploaded documents. Manual data entry is gone. Staff now review outputs rather than produce them.
3 days → 4 hours
Client onboarding time
"The process used to follow the documents around. Now the documents follow the process."

A dance studio management platform had complex billing logic — stacking benefits, multi-class discounts, family caps — with no automated test coverage and approximately 20 undiscovered bugs.

Automated tests written — ~20 billing bugs found
An interactive AI avatar deployed in a Swiss beauty store was silently draining API credits due to WebSocket connection issues. Customers were getting dropped mid-conversation.

From idea to working prototype

An existing React web app needed a CMS backbone to power a browsable manufacturer directory, replacing a hardcoded data approach that the team couldn't maintain.
Integrated Strapi CMS into the existing codebase — browsable directory with search, filtering, and user favourites. Clean handover with editorial workflows the team could manage themselves.

A fashion resale startup needed a demo tool to show investors how AI could let buyers virtually swap clothing on photos.
An AI-powered inpainting tool: users select a clothing region, enter a prompt, and the tool generates a composite image with the outfit replaced. Backend chains three model calls — segmentation, inpainting, and compositing — via Stable Diffusion.
3-stage
AI pipeline: segment → inpaint → composite
