What I'm looking for

I'm looking to build and lead scalable backend systems, especially distributed and event-driven platforms, while working closely with high-quality teams on technically challenging products.

I work with JS stack for over 9 years.

Main Tech stack: NestJS, NodeJS, ReactJS, MySQL, Kafka, Redis

I've also made a few apps using React Native.

Recently I finished two short term contracts for american companies (through G2i), helping them building scalable and robust systems in a fast-paced environment.

I have experience with distributed systems, event-driven architecture, clean arch/clean code, spec driven development.

I've worked in robust software that expects thousands of requests per second, big frontier lab projects, clinical systems, sales, ERPs, CRMs, Whatsap integration systems.
