Time tracking system – Lead Developer & Agile Master

Byuser

In summer 2021, I stepped in as Lead Developer and Agile Master to guide four frontend summer employees enhancing an internal time-tracking system. The project was about turning an internal time-tracking tool into a revenue-generating SaaS product, covering Stripe payments, accounting integrations, and faster, low-cost deployments — enabling new paying customers and long-term scalability. By summer’s end, the product had new paying customers, faster deployments, and all interns had secured jobs — one joining the company full-time.

Traffic Control Platform – Fullstack Developer

Byuser

As a fullstack developer, I helped unify multiple legacy traffic control systems into a single modern platform.

I also enhanced the user experience with a refreshed WPF client and supported operators through testing and training. The result was a seamless transition with zero downtime, high code quality, and full adoption across traffic centers—earning strong praise from leadership
