PROFILE
Frontend Developer with 4+ years of commercial experience building high-performance, production-grade
interfaces with React, TypeScript, and Next.js. Progressed to a top-3 team contributor by owning complex, cross-
cutting UI features end-to-end for an enterprise B2B SaaS ERP product — including virtualized trees, drag-and-
drop editors, Excel-like grids, adaptive canvas modals, and synchronized filters. Skilled at turning ambiguous
requirements into shippable, resilient features and at integrating AI coding agents (Claude Code, Codex) into team
workflows to speed up onboarding and raise engineering consistency.
WORK EXPERIENCE
Jul 2024 – Aug 2026 Frontend Developer, HESH (Product, B2B SaaS ERP)
• Owned the team’s most complex cross-cutting UI — virtualized trees, drag-and-drop
editors, and Excel-like grids handling hundreds of thousands of rows without noticeable
performance loss.
• Cut code review turnaround for large features from ~1 day to ~4 hours by introducing
shared engineering conventions, reducing PR rework and unblocking the team faster.
• Set up Playwright E2E tests and an AI-assisted dev workflow (Claude Code + GitHub
MCP), roughly halving bugs reaching production and speeding onboarding for 2
developers.
May 2023 – May 2024 Frontend Developer, Uvoteam (Product, EdTech)
• Improved page load performance by ~60% via code-splitting, lazy loading, and image
optimization, bringing INP, FCP, and LCP into the “good” range.
• Reduced JS bundle size by ~30% by migrating from ES5 to ES6, replacing legacy APIs,
and removing deprecated code.
• Migrated the app to Next.js + Tailwind and built targeted marketing landings, driving a
noticeable lift in organic traffic and search rankings.
Jan 2022 – Jan 2023 Frontend Developer, Bleecker (Outsource)
• Built dozens of landing pages across one-off projects and ~10 ongoing client accounts,
growing traffic several-fold after launch.
• Refactored client codebases into reusable component modules, reducing bugs and
speeding up new feature delivery and developer onboarding.
EDUCATION
2012 – 2017 Master’s Degree — Mining Engineering and Open-Pit Mining Development,
Kryvyi Rih National University
• Coursework in technical and analytical subjects with programming/automation
components, building a foundation for structured, data‑driven problem‑solving.
• Thesis: modeling and performance calculation of industrial equipment, developing
quantitative models to predict and optimize system behavior.
• Contributed to project‑based coursework involving data analysis and technical
calculations within small teams.
