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.

Taxi Ordering App – Backend Developer

Byuser

I played a key role as a backend developer in a project resulting in launching a modern taxi booking, dispatch, and payment app. The backend services enabled real-time vehicle tracking, secure NETS mobile payments, and instant PDF receipts for riders. Built on a scalable AWS Fargate microservice architecture, the MVP launched on schedule, ran reliably, and quickly gained strong user adoption — driving more ride bookings and positive customer reviews in its first month.

Large-Scale Integration Project – Scrum Master / Architect / Fullstack Developer

Byuser

The project was about restarting and delivering a complex manufacturing system integration after an initial halt. As Scrum Master, architect, and developer, I led the team in connecting ERP/MES, production lines, robotics, and quality systems using an agile, test-driven approach. The result was an on-time delivery with most defects caught early, a flexible message-broker architecture that reduced change costs, and DevOps practices that improved transparency and speed — earning strong customer praise.
