What I'm looking for

I'm open to senior frontend and full-stack (React + Node.js) roles. I work fully remote.

At Bell Integrator, I develop AlfaGo services with React, including the AlfaGo PWA and an internal application for architectural decision-making. I also write and maintain the Node.js/HapiJS BFF layer, using Redis as a key-value store.

I’ve used Module Federation with Webpack and RsPack to split a frontend into independently deployable micro-frontends, and built logistics applications with Next.js. I maintain automated tests and Jenkins CI/CD pipelines, and have reduced bundle size, Docker image size, and build time while profiling Core Web Vitals with Lighthouse.

Before Bell Integrator, I contributed to the Otkritie Investments PWA and web application at IT People Crowd, and built React applications for regulatory documents and drilling data. I’m open to senior frontend and full-stack roles using React and Node.js, and work fully remote.
