Vaidotas Valuckas

Working on the open source Gradle build tool.

Architected and implemented continuous delivery processes and tooling. Drove modernization of a legacy startup platform. Introduced current day development and delivery practices. My initial focus was on the delivery aspects: - introduced containers into the delivery process, set up the tooling stack and processes for continuous delivery - Jenkins, Nexus, Docker registry. Those are used to date. A more detailed overview can be found in the Medium article here: https://medium.com/@rieske/software-delivery-workflow-at-casumo-664e20eb8639 - introduced and kept promoting clean coding practices, test-driven development, higher-level black box testing, contract tests for the APIs - the ingredients required to successfully build and deliver maintainable and resilient services in a distributed system. - developed tools to enable easy observability of microservices - automated dashboards for key operational metrics that get created/updated automatically on each release. Once the continuous delivery processes were established, I shifted the focus on refactoring/cleaning up/splitting/rewriting parts of the legacy monolith: - tested the untested - scaled out the previously unscalable - fought complexity, overengineered code - made services highly available and deployable without downtime - split out and rearranged services from big-ball-of-mud monoliths into decoupled domain focused services

Helped to build a highly resilient distributed source code analysis platform. Took the lead in automating AWS based deployment infrastructure. Created a version controlled continuous delivery pipeline spanning from a push to version control system down to a deployment into production environment.
