Luck-Driven Development

Tomáš Štěstí

Senior Software Developer

Building production software since 2015 across a crypto exchange, global logistics, scanless retail and telecom. I own services end-to-end on the JVM (Java, Kotlin, Spring), integrate the hard stuff — blockchain, payments, real-time tracking — and have worn the DevOps, Scrum Master, competence-lead and product-owner hats along the way.
Where others rely on luck, I build a system on it.
