They arrived without a spec. They left as working systems.
I own the customer portal of a telematics provider, used daily by thousands. Vehicle tracking, reporting, alerts and decision-support fleet services — from clarifying business needs to production and continuous development.
For a service company, I designed and built a central system that runs several custom business processes. In each, payment flows, invoicing and customer balances work as one, coordinated across multiple external providers.
A parking service built on vehicle data. At partner companies, drivers park with one tap; for car-sharing fleets, parking is fully automatic. The company gets a single invoice and sees every session.
For a solar installation company, I built a custom CRM and operations system. Sales, quoting, procurement and installation now run in one shared system.
For a toll-reporting service, I built a subscription renewal platform that has processed over HUF 100 million and thousands of invoices. Multiple currencies, payment methods and service periods; email campaigns and follow-up guide customers through renewal.
For three years I ran a guesthouse, a restaurant and a buffet at Lake Balaton. Since then I know what it means when a system has to work at seven in the morning.
