Built a production AI system for a UK defence team. 100% Job Success Score on Upwork. Founder of two AI-first SaaS platforms (Resolved AI, Vocara). If you've got a manual process eating your team's hours, message me, I can usually tell you within 15 minutes whether it's worth automating.
I design and deploy n8n, Make, and custom AI workflows that survive production, not just demos. Most of my work lives in operations-heavy teams: care, compliance, sales ops, and anywhere documents and data move between systems faster than humans can keep up.
━━━━━━━━━━━━━━━━━━━━━━━━━
RECENT BUILDS
━━━━━━━━━━━━━━━━━━━━━━━━━
→ Referral intake pipeline for a UK care provider: 20-minute manual triage cut to under 2 minutes per case. Monitors inboxes, extracts structured data from PDFs with Claude, validates against existing records, and pushes to the care platform — fully unattended.
→ Compliance document generator: produces CQC-compliant assessments, risk documents, and medication charts on demand. Formatted, accurate, ready to send. Replaces hours of coordinator time per week.
→ Multi-agent AI proposal system: researches each job, drafts tailored cover letters, generates supporting materials. Cut proposal writing time by ~80%. I use it on myself.
→ Zoom call automation: auto-transcription, AI meeting notes posted to Slack, plus idle-time video generation via Google Veo. About 4 hours saved per coordinator per week.
━━━━━━━━━━━━━━━━━━━━━━━━━
WHAT I DELIVER
━━━━━━━━━━━━━━━━━━━━━━━━━
▪ End-to-end n8n and Make workflow design, build, and deployment
▪ API integrations (REST, webhooks, OAuth) connecting any combination of platforms
▪ AI/LLM integration — OpenAI, Claude, custom multi-agent systems embedded into business processes
▪ Document AI: PDF/DOCX generation, structured extraction, compliance-formatted outputs
▪ Database design and integration — Supabase, PostgreSQL, Airtable
▪ Voice and video pipelines: speech-to-text, AI transcription, multilingual voice logging
▪ Error handling, logging, and monitoring — so your automations don't silently fail at 3am
━━━━━━━━━━━━━━━━━━━━━━━━━
WHY ME OVER THE NEXT 50 PROFILES
━━━━━━━━━━━━━━━━━━━━━━━━━
▪ 100% Job Success Score. Every contract, every star, every time.
▪ UK-based, defence-sector background. Built systems with real compliance and security requirements — not weekend tutorials.
▪ Founder of two AI SaaS products, including Vocara — a voice-powered care compliance platform for UK domiciliary providers. I've shipped to paying customers, not just clients.
▪ Software Engineering degree (University of West of England). Trained engineer, not self-taught from YouTube.
▪ Sub-30-minute response time. I document everything so you're never locked into me — you own the build.

HOW TO START
━━━━━━━━━━━━━━━━━━━━━━━━━
Send me 2-3 lines describing the process you want to automate. Within 30 minutes I'll come back with whether it's worth automating, what the rough scope looks like, and an honest estimate of what it'll cost. Sometimes the answer is "don't automate this yet" — and I'll tell you that too.
