- refactored 7 y.o. 5M Lines of Code legacy functional programming projects to 120K LoC in a matter of months, while reducing the database footprint from 5Tb only to 300Gb
 - ported numerous services from MongoDB and MySQL to complex CQRS-ES solutions on top of PostgreSQL and ScyllaDB
 - implemented managed database schema denormalization and storage segregation approaches, trained the respective teams (how and when to denormalize, and what to archive)

My definition of high-load starts with 100Gbit/s per single serving node.

My definition of big data starts from 2Tb per workload day.
Do not tolerate mushroom management, broken retrospective and escalation chains, dual subordination, psychological contracts, any and every type of workplace deviance.

Problems and Risks comes always on top of the Solutions.
I don't "Make Compromises" I Build and Execute Strategies.

Heavily biased against Microsoft solutions.

Relying on fastest possible TDD and local development cycles;
Relevant tunneling tools (Telepresense, Okteto) with an individual, completely isolated remote dev env otherwise.
