WORK EXPERIENCE

AnvilEight — Senior Front-End Engineer Oct 2018 – Present | Kyiv / Remote

▸ World Food Programme (WFP) & UN data platforms (React · Angular · TypeScript · AWS · D3 · Leaflet)
• Long-running work across UN / ILO data platforms (World Food Programme and a related labour-standards
programme) covering 50+ countries — dashboards, interactive maps, charts, complex forms, and PDF / Excel
reporting. Returned to the core React product across several phases, with a period on the Angular platform in
between.
• Wrote AWS Lambda functions for data import / export that are still running in production today, years later.
• On the Angular platform, built multi-module applications with D3 and Leaflet geo-visualisations, Excel export,
Keycloak SSO, and multi-language support.
• Currently helping move the React front-end out of server-rendered Django templates into a standalone SPA, and
handling authentication and access for external (non-staff) users.

▸ Real-time Biomedical Signal App (React · Electron · TypeScript | 2025 – Mar 2026)
• Built an offline-first desktop app for recording and reviewing multi-channel biomedical signals — live charts, history
playback with zoom, and side-by-side signal comparison.
• Eliminated UI freezing under heavy real-time data by implementing a virtualized windowing strategy — keeping
only the active frame in memory and streaming older data to local disk; stored sessions per patient with import /
export between workstations.

▸ UK Farmers Marketplace (Flutter · Dart · GraphQL · in-app purchases)
• Shipped a cross-platform mobile marketplace for UK farmers from zero to production release — product listings,
cart, in-app purchases, and a GraphQL data layer.
• Managed performance profiling and the release pipeline on both iOS and Android.

▸ Internal CRM → SaaS Product (React · TypeScript · REST)
• Developed an internal HR and resource-management platform (employee directory, leave booking, equipment
tracking) that was later productised as a SaaS solution, with a separate customer-facing invoicing and account
module.

▸ Mental Health App — COVID Support (Flutter · Dart | UK market)
• Built a mental-health assessment and exercise app with an adaptive test and personalised exercise
recommendations to support people during pandemic isolation.
Engineering Practices & Mentoring
• Mentored ~10 junior and mid-level developers over my career, focusing on code quality, architectural thinking, and
best practices.
• Brought a stalling CI build down from ~1h40m (it kept hitting the timeout and failing the pipeline) to ~1h — without
touching product code: added missing build caching, audited and removed unused dependencies, and finished a
partial JS→TypeScript migration to cut compilation overhead.
• Drove state-management migrations: BLoC → Riverpod (Flutter), Redux → MobX, and Redux → Zustand —
reducing boilerplate and improving DX each time.
• Ran systematic code reviews enforcing consistent patterns, performance-conscious rendering, and accessibility.

Maincode Agency — Front-End Developer Apr 2018 – Oct 2018 | Kharkiv
• Built React SPA features with Redux and Google Maps integration; delivered a Nuxt.js / Vue.js e-commerce project
with Vuex and Axios.

EliteIT — Markup / Front-End Developer May 2015 – Apr 2018 | Kharkiv
• Delivered 100+ projects — landing pages, blogs, online stores — building a strong foundation in semantic HTML,
CSS3 / SASS / LESS, JavaScript, jQuery, and Gulp; introduced Vue.js for interactive form components.

PERSONAL & SIDE ENGINEERING

▸ getpickio.com — Giveaway / Randomizer SaaS (self-shipped to production)
• Designed and shipped a full-stack giveaway platform end-to-end — transparent winner selection, public results,
billing. Frontend: Next.js + React (Feature-Sliced Design), TypeScript, Mantine, TanStack Query, Zustand.
• Built the backend solo: NestJS + Prisma / PostgreSQL, Redis + BullMQ queues, JWT / Passport auth, and social-
participant scraping (Instagram / Threads via Playwright).
• Other Node.js / NestJS side projects: a crypto exchange terminal (real-time market data, exchange APIs, automated
trading), Telegram automation bots, and an LLM content-rewriting pipeline.
• Backend above comes from personal projects — front-end is my primary focus, and I am comfortable owning
backend tasks (Node.js / NestJS) when a role needs it.
