You bring
An incomplete brief, a fragile workflow or a product decision that cannot stay unresolved.
Selected work
Three client products, each shaped around a different business and delivery challenge.
Co-built the ERP that supports AllSafe's self-storage and vehicle-rental operations across 53 locations. I lead front-end delivery and own work spanning contract lifecycles, debt collection, billing, mobile identity scanning, analytics and AI-assisted reporting.
Products I founded and continue to design, build and operate.
A knowledge workspace for links, notes and files with keyword and semantic search, AI answers backed by source citations, and queued content ingestion and enrichment.
A social prediction game where friends create private groups, lock in their picks before the show and follow a leaderboard that updates as results arrive.
I take complex product work from business problem to reliable software in production.
Turn an incomplete brief into focused product work across web, mobile, APIs and data.
Modernise fragile systems, remove recurring failures and make delivery safer without pausing the business.
Handle payments, real-time workflows, mobile integrations, automation and AI features grounded in real data.
