Work Experience

2019 — Now
Front-End Developer at EXNOA LLC

I'm working on modernizing applications for online gaming platforms. As a front-end engineer, I'm responsible for building the front-end and backend-for-front-end using React and GraphQL.

2016 — 2019
Software Engineer at LLC

I worked to modernize the authentication platform.

Our team replaced a monolithic application built in PHP with a microservice built in Node.js and changed the infrastructure from on-premise to AWS.

As a software engineer, I built infrastructure with AWS, front-end with Node.js, and React.

I contributed to improving the efficiency of application operations through the adoption of infrastructure monitoring SaaS, infrastructure as code, and CI/CD pipeline.
