PROFILE
Marcin Wadon
Michał Wadoń developed and enhanced spend transaction workflows for the Constellation-Labs/tessellation repository, focusing on secure, auditable, and scalable blockchain transaction processing. He implemented end-to-end support for allow spend transactions, integrating storage, validation logic, and DAG-based consensus mechanisms using Scala and Java. Michał refactored global and currency layer transaction handling, introduced robust authorization and expiration checks, and expanded automated test coverage to include edge cases and CI/CD reliability. His work included updating API documentation and improving error handling, resulting in a hardened backend that supports new business use cases while reducing manual oversight and increasing deployment confidence.
