Work experience

Full stack software engineer

from 07.2026 to now (3 months)
SP-Lutsk, Lutsk (IT)

Own features end-to-end — data model, API and UI — across three production SaaS platforms, moving fluidly between backend services and the interfaces they power.

Extended into backend work: Django services, data modelling, and the async-job infrastructure behind them, while continuing to lead frontend architecture.

Built the real-time AI support chat over WebSocket, and the k6 load-testing suite covering admin, tenant and shared flows, on a multi-tenant dropshipping platform.

QA engineer

from 11.2022 to 06.2023 (8 months)
SP-Lutsk, Remote (IT)

Built the load-testing and end-to-end automation foundation: k6 throughput scenarios, browser E2E suites over critical user flows, and Grafana dashboards over InfluxDB.

Designed an order-independent load-test architecture in which every scenario discovers its own valid data at runtime and runs safely in any order, subset or concurrency level.

Partnered with developers and product on triage, learning to write a defect report that can be acted on without a follow-up question.

Eight months observing how production systems actually fail - the instinct for failure modes that still shapes how I write and review code.

Front-end developer

from 10.2022 to 06.2026 (3 years 9 months)
SP-Lutsk, Lutsk (IT)

Architected and delivered a complete CRA → Next.js 16 (App Router) and TypeScript migration on a high-traffic SaaS platform, then maintained the patterns it introduced.

Owned frontend delivery of large multi-tenant subsystems - multi-warehouse operations, quoting, and vendor SKU mapping - on a logistics platform, across roughly 218 feature branches.

Rebuilt a large client-rendered SPA on App Router architecture, where routing, internationalization, state persistence and auth all had to be re-thought rather than ported.

Took performance on as a measured discipline: tracked Core Web Vitals and fixed what the numbers pointed at - render-blocking resources, layout shift, and unaudited third-party scripts.

Owned internationalization on production platforms, including English and Chinese localisation on a logistics platform.

Took on the work nobody volunteers for: legacy migrations, cross-browser edge cases, and test coverage - including Cypress + Cucumber E2E suites and snapshot tests in CI.
