At SE «Infotech», I own the frontend architecture for an enterprise GIS platform, using Feature-Sliced Design, Atomic Design, and Inversify to make feature delivery parallelizable and services testable in isolation. I also built interactive mapping with the ArcGIS JS SDK, including custom layers, spatial queries, and geospatial visualizations used daily by end users.

I've delivered cryptocurrency wallets, transaction flows, two-factor authentication, role-based access control, and end-to-end admin panels at Unit Space. At Zfort Group, I built analytics dashboards and data visualizations with Chart.js and Recharts, turning backend data into client-facing reporting tools.

I establish test suites in release processes, review code, mentor junior developers, and contribute to scoping, architecture, and release planning. I also publish the architecture I use at work through an open-source Feature-Sliced React and Effector starter.
