WORK EXPERIENCE

React Developer | Grandia Solutions Mar 2024 – Present Remote
● Engineered 10+ core UI features across a 10-person team, including a hub-cloning system that eliminated
manual reconfiguration of 2–3 reports per hub (saving up to ~9 minutes per operation across 13 report types),
and a date-filtering system replacing full-dataset pagination for multi-year project histories.
● Architected and maintained production React/TypeScript applications (Redux Toolkit, Ant Design,
Tailwind CSS) integrated with the Atlassian Jira platform via Forge, working full-stack across scalable
front-end architecture, backend resolvers, and REST APIs.
● Set up CI/CD pipelines using GitHub Actions and Bitbucket Pipelines to automate build, test, and
deployment workflows for the team's React application, shortening release cycles and reducing manual
deployment overhead.
● Diagnosed and resolved a critical authentication vulnerability through systematic troubleshooting,
implementing permission validation to close the gap; separately triaged and fixed ~10 dependency
vulnerabilities flagged by Snyk.
● Designed and deployed an agentic AI workflow with Claude Code custom subagents for automated bug
triage — covering ticket fetching, code analysis, root-cause identification, fix suggestions, and test generation
— cutting resolution time from 1–2 hours to 30–40 minutes.
● Designed 4 Jira automation rules and custom fields, reducing manual workflow steps and improving team
task-management efficiency.

Export Manager | PITAYA Apr 2023 – Nov 2023 Ukraine
● Managed international B2B client communications in English and German across multiple markets,
demonstrating strong cross-cultural communication skills; coordinated logistics for international trade shows.
