I build tools for work that matters.
Thirty years building the back-office systems other organisations run on — care services, supported housing, consumer goods, live production. Now I build and deploy practical tools that close the gap between what an organisation has and what its people need to do their work.

Working software
Each of these runs. Every page says what it does, what’s built, and what I’d change for a real deployment.
AI contributes a lens. Teachers retain the judgement.
Assessment Desk
A classroom assessment pipeline designed so that tasks, evidence, transformations and suggested judgements can be inspected rather than merely trusted.
View project ↗Live production, from first brief to final cost.
Production Desk
A connected back-office workspace for small businesses delivering live, streaming and post-production work.
View project ↗Small teams. Clear outcomes. Credible impact.
Impact Desk
A working example of how a focused CRM can help a resource-constrained nonprofit manage relationships, programme activity and measurable outcomes.
View project ↗Data never arrives clean. Build for that.
Ingest Lens
A working intake layer that turns fragmented documents into reviewable records inside the operational hubs where human attention is needed.
View project ↗Keep what works. Record where.
Image Prompt Studio
A personal library and composition tool for turning reusable visual references and model-specific prompt observations into reviewable GenAI image prompts.

Experience labs
Working prototypes at the meeting point of composition, analysis, immersive media and interaction design.
One idea. Six possible forms.
Crowded Mind
An identity-led website that turns the moment before an idea chooses its medium into an interactive editorial experience.

Services & consulting
I build tailored operational systems for businesses and nonprofits — the same work I did inside Home Group, Max Factor, Norm Howe & Associates and Absolute Live, now done end to end.
Operations Consulting
Organising complex multi-entity structures, designing practical workflows, and implementing communication systems that fit how your team actually works.
Custom Applications
Building tailored, full-stack web applications to solve specific operational challenges, replacing fragmented spreadsheets and disjointed tools.
Technology Integration
Turning fragmented input from email, documents, forms and existing tools into connected, reviewable information inside the operational hub where human attention is actually needed.
See fragmented input become usable data ↗Deployment includes support. An operational system isn’t finished when it ships — the work changes, and someone has to change the system with it. I build on a retainer basis: design and implementation first, then ongoing support for as long as it earns its place. That’s the difference between a system an organisation runs on and one it works around.
About the work
Domain experience first. Technology in service of the problem.
I’m Mark Slater. Fourteen years in supported housing for adults with complex needs, ending as Area Manager across Home Group’s Surrey services — budgets, safeguarding, inspection, multi-site operations. A film-scoring career built alongside it, recording with the London Symphony Orchestra at Abbey Road, then Los Angeles and multi-camera live-stream production. Now Tokyo, teaching at Gakugei University International Secondary School.
I’ve been building the systems those organisations run on for thirty years — back-office reporting at Home Group; regional sales reporting for Max Factor; portfolio, budget and forecast tools for the president of Norm Howe & Associates, along with the copy design, review and send automation behind their mailing campaigns; production and operations tooling for Absolute Live. The pattern doesn’t change: take a daily operational pain point and turn it into something that either puts the right information in front of someone, or performs reliably the repetitive procedure that used to take hours and go wrong by hand.
