Paulius Labanauskis
Principal Engineer & Technical Architect
Consulting
I work with a small number of fintech and regulated-platform teams each year — greenfield architecture, event-sourced transaction systems, performance turnarounds at scale. paulius@labanausk.is.
About
Fintech-specialized technical architect with 15+ years building financial infrastructure across banking, banking-as-a-service, and digital assets. Built regulated platforms from scratch twice. Led an emergency banking migration in four weeks, zero customer disruption. Once diagnosed a Datomic bottleneck by reading the database internals over a weekend — that took API p95 from 60s timeouts to 200ms. Equally fluent in Clojure and C#/.NET, both used in production at scale. I build lean teams that ship production systems, not process.
Currently
Building an EU-regulated institutional digital asset platform: event-sourced transaction engine, multi-custody, multi-bank, full compliance stack.
