01 / about

About

I build and maintain production frontend applications: architecture, reusable UI, data-heavy interfaces, and complex forms. I work closely with design and backend, and care about code that stays readable after the first version.

Currently at Garpix, I work on commercial React + TypeScript applications — from UI Kit and API integration to tests and legacy modernization. I am looking for a Frontend Engineer / Middle Frontend Developer role in a product team, preferably remote and international.

03 / focus

Engineering focus

The work I actually do — not a list of buzzwords.

01

Frontend Architecture

Structuring React + TypeScript applications so they stay maintainable as they grow. That includes reusable patterns, clear data flow, and modernizing legacy code without a rewrite for its own sake.

02

UI Systems

Reusable components and UI Kit work in production: consistent interfaces, predictable component APIs, and close collaboration with design in Figma.

03

Forms & Data

Multi-step forms, typed validation, and data-heavy screens — fetching, caching, filtering, sorting, and pagination — with React Hook Form, Zod, and RTK Query.

04

Testing & Quality

Jest and React Testing Library on critical UI and business logic. Code review is part of the regular workflow, not an afterthought.

05

AI-assisted Engineering

Cursor and GitHub Copilot for code generation, refactoring, boilerplate reduction, test generation, debugging, and exploring implementation approaches. AI-generated code is reviewed before it ships — the engineering judgment stays with the developer.

05 / work

Engineering work

Types of commercial frontend work rather than a public GitHub showcase.

01

UI / Component Architecture

Reusable component layers and UI Kit work in commercial React applications — consistent interfaces, less duplication, and a clearer path for new features.

02

Complex Forms & Validation

Multi-step forms with React Hook Form and Zod: typed validation, fewer re-renders, and less boilerplate on large form flows.

03

Data-driven Interfaces

REST-backed screens with fetching, caching, filtering, sorting, and pagination using Redux Toolkit and RTK Query.

These examples are based on commercial projects and cannot be publicly disclosed.
