At Worknetika, I helped bring an AI-powered HR platform to release by building candidate search, recruiter tools, interview scheduling, a WebSocket chat, Excel reporting, and a browser extension for parsing resumes and vacancies.

I design frontends to stay flexible as products grow: I decompose APIs, organize layers with Feature-Sliced Design, build reusable components, and document systems. I reduced the HR platform’s loading time by decomposing RTK Query APIs and added error handling, testing, animations, and loading states.

At CustomApp, I delivered frontend products for neural-network training and blockchain workflows. For Filemarket AI, I built the complete voice-data collection flow, including microphone validation, browser WAV recording, AI dialogue, progress tracking, and session recovery; for an NFT-mining platform, I connected React interfaces to Solana Web3 and Anchor transactions.

I’m comfortable entering legacy codebases, refactoring critical functionality, fixing production bugs, and working across backend, design, and QA. I’ve progressed from junior to middle frontend developer, mentored junior developers through task planning and code review, and value autonomy, strong feedback, and technical decisions focused on real customer problems.
