Hopeman, Moray, Scotlandmark@marideco.ukmarideco.ukHiring profile & working models

Profile

Practical systems builder with 15+ years of first-hand experience in operations, compliance, team leadership and technical field work. I turn real business friction into useful AI integrations, workflow tools, websites and working prototypes.

I use AI development tools to deliver quickly, while directing the architecture, understanding each codebase, testing behaviour and writing or correcting code when needed. My strongest advantage is the combination of operational judgment, technical curiosity and the ability to explain complex systems plainly.

01

Selected systems

Workbench

React · Modular application platform

Local-first modular platform with installable business tools, shared operational values, cross-module actions and isolated module failures. Designed to integrate current spreadsheets, files, APIs and systems without forcing wholesale replacement.

Health & Safety Operations

React · TypeScript · Workflow policy

Working operations platform covering field reporting, triage, investigations, corrective actions, work queues, routing rules and audit history. Role-based authority and controlled state transitions keep responsibility and evidence clear.

Fieldwork Tracker

JavaScript · IndexedDB · Supabase · PWA

Offline-first pay-per-task tracker built for a real operational need, with day/week/month/year views, bulk entry, expected earnings, completion analysis, data export and optional multi-user comparison.

AI Enquiry Workflow

TypeScript · Controlled AI workflow

Interactive workflow demonstrating bounded intake, retrieval from approved context, evidence-linked drafting, explicit human approval and retained audit events. Unsafe instructions are held without retrieving context or enabling approval.
