Artak Harutyunyan

I’m a Senior Frontend Engineer with 7+ years building production React/TypeScript applications for fintech, SaaS, and AI products. I specialize in scaling legacy codebases, improving large-dataset performance, and delivering real-time, AI-integrated user experiences.

At Altamira.ai, I architected a strict TypeScript React frontend and stabilized complex AI re-analysis and auto-save flows by separating TanStack Query server state from Zustand UI state. I built a real-time job system with Server-Sent Events (including Last-Event-ID replay) so users can see AI generation progress without polling.

I also integrate end-to-end AI pipelines into the UI, turning LLM-driven screenplay analysis into structured scenes/cast/locations, including an @mention picker that folds entity descriptions into generation prompts. On the product side, I designed a multi-track timeline editor (magnetic snap, clip resize, seam drags) and paired it with an FFmpeg export pipeline rendering MP4/WebM/MOV/GIF.

Quality and reliability are how I work: I develop test-driven throughout with Vitest + React Testing Library + MSW for unit/integration and Playwright for e2e—no production code merged without a failing test first. Whether optimizing AG Grid for 50,000+ record datasets, migrating from legacy code with zero business disruption, or refactoring brittle UI flows into reusable modules, I aim to ship maintainable frontend systems that stay fast under real load.
