Software Development
Custom software built for the public sector's long timeframes. Web applications, registries, procurement integrations and back-office systems designed for reliability, auditability and a decade of service.
Sixty Four is a Tallinn practice of engineers, designers and strategists building digital infrastructure for ministries, municipalities and the institutions that serve them. We work inside public tender frameworks — the boring, load-bearing part — and deliver systems that are simple, durable, and readable to the people who must live with them for a decade.
