Commercial development experience, most recent first.

  1. Frontend Engineer

    Jul 2024 — present

    MetaLamp

    // remote

    TypeScript React Effector Module Federation MobX Apollo GraphQL Recharts Keycloak FSD

    Building five products inside ADV’s advertising-analytics ecosystem — used by major brands to plan campaigns, track marketplace performance and measure ROI.

    Sped up Algorithm's UI by ~27%

    Removed dead code paths, cut redundant re-renders and fixed accidental O(n²) scans — with no regressions. Separately migrated authentication to a new provider in production: active sessions preserved, feature-flagged rollout, zero downtime.

    Rewrote ClientSpace's report builder from O(n²) to O(log n)

    Pivot tables that used to lock the tab now feel instant, even as the number of dimensions grows.

    Designed Points LK from scratch — a microfrontend system

    Module Federation shell + Track + Display + a shared UI-kit, all on Feature-Sliced Design. Teams ship their modules independently against fixed contracts.

    Integrated maps and charts across modules

    Yandex Maps 3 (geo segments) into Display, and Recharts (Ozon / Wildberries analytics) into Track.

    Built ROI Navigator

    Brand-performance dashboard with dual modes — multi-brand comparison and single-brand deep dive — reusable trend cards (sales / share / price), PNG and Excel export, and i18n.

  2. Frontend Engineer & Scrum Master

    Sep 2022 — Jul 2024

    PizzaFabrika

    // remote

    React Redux Next.js TypeScript SCSS Jest Docker GitLab CI/CD FSD

    Frontend and process work across a food-delivery ecosystem — customer storefront, account area and internal admin tools, serving thousands of daily users.

    Migrated a live B2C product, island by island

    Moved it from Backbone + CoffeeScript to React + TS + FSD with zero downtime — feature work never paused. New modules landed straight in FSD; legacy moved over gradually.

    Owned the customer account area through peak load

    Full cycle from spec to release through lunch and dinner peaks, with Jest / Enzyme coverage on the critical paths.

    Built an SSR storefront on Next.js

    Strong SEO and broad WebView compatibility for the in-app browsers used by clients.

    Ran Scrum Master duties for ~2 years

    16 sprints in a row with no missed commitments, fewer night releases, and several juniors growing into confident middles.
