Founder-built SaaS platform

Veterinary clinic SaaS platform built independently for real clinic operations, including web app, backend APIs, and mobile app.

Case study by Cristian Simion.

Role

Founder and sole engineer, responsible for architecture, implementation, infrastructure, and ongoing technical delivery.

Problem

Clinics were juggling disconnected tools for daily operations and needed one reliable platform.

Solution

Built a full-stack product: web application, backend APIs, and mobile app, designed for daily production use and long-term maintainability.

Impact

  • Shipped and operated a complete SaaS product under single-engineer ownership.
  • Moved clinics from fragmented workflows to one production platform.
  • Demonstrates end-to-end ownership across product, backend, and infrastructure.
