Founder & Sole Developer — t-ket (tketops.app)

Multi-tenant SaaS for ticketing and work-order management in facility management and construction, replacing scattered exchanges over WhatsApp, email and Teams. First client already in production.

Founder and sole developer of t-ket, a multi-tenant SaaS for ticketing and work-order management aimed at facility management and construction, replacing scattered exchanges over WhatsApp, email and Teams. I designed and built the entire architecture and backend, with occasional help from a freelance front-end developer: a full domain model (sites, buildings, zones, rooms, roles, teams), a 6-status Kanban board, multi-view planning, .ics and .xlsx exports, and automatic work-order ingestion by email. I also built the SaaS billing engine: per-session seat counting, overage handling with budget safeguards, price lists, capped discounts and a white-label mode for partners. The platform is in production with its first client.
