Wrote a query optimizer to speed up and increase the performance of a custom query language executor. To get this objective, instead of a direct execution of the query, an intermediate execution plan was generated, using the nodes and edges volumetrics to find the statistically best execution order.

Lead a JavaScript to TypeScript incremental migration of a React project.

Started a rearchitecture of a complex distributed graph database with a custom protocol to Neo4J.

Introducing team members to TDD, and empowering the next leaders of the project to be able to carry on the project.
