Challenge

Small businesses and product teams needed working software across unrelated domains, often with limited time, existing systems, and evolving requirements.

My Role & Ownership

Delivered focused web and mobile products directly for clients, adapting architecture and scope to each business rather than forcing every project into the same shape.

Delivery & Engineering

  • Built mobile and web workflows for Regiofood and Taxicar services.
  • Developed Bot.Media Charts and Hand Writer as specialized user-facing software.
  • Created Property Farmer for property-oriented workflows and information management.

Result

These projects built broad delivery experience across domains, client relationships, legacy constraints, and the practical trade-offs required to ship useful software.

Highlights

Six different products grouped by the freelance delivery experience they represent.
Web and native mobile work across varied business domains.
Direct responsibility for turning client needs into maintainable releases.
