What I'm looking for

I seek senior engineering roles where I can build scalable, high-quality systems, collaborate cross-functionally, and apply UX-informed development to drive measurable product impact.

I am a senior software engineer with over six years of experience building reliable, high-performance web and desktop applications using Node.js, React.js, NestJS, Electron, and related technologies. I have optimized production systems—improving API response times by 40%—led front-end feature development such as a React-based image editor, and contributed to architecture, documentation, and maintainability for platforms used by major beverage brands.

My background includes enterprise and embedded/desktop projects across microservices and monolithic architectures, working with databases (MongoDB, MariaDB, PostgreSQL, Firebird), messaging (RabbitMQ, MQTT), and DevOps practices. I pair technical craftsmanship with UX/UI training to deliver usable, performant solutions and collaborate effectively across teams.
