Andrii Blagodyr

I’m a Senior Frontend Developer with 10+ years of experience building enterprise-scale web applications, specializing in React, TypeScript, and data-driven platforms.

At Comet (November 2021–now), I lead frontend and BFF architecture for a self-hosted and cloud-based meta Machine Learning platform. I led the frontend development and BFF architecture of the Model Production Monitoring module—one of the platform’s most critical application blocks—and I deliver end-to-end solutions by collaborating closely with backend engineers, designers, and product managers.

I focus on real-time, data-heavy experiences: I implemented advanced visualizations and custom charting with D3.js and Plotly.js (React Plotly) to enable monitoring, streaming analytics, and predictive anomaly explanations. I also optimize complex state and data flows using Redux Toolkit, React Query, and Zustand, and I strengthened client-server validation with Zod across sync-heavy streams.

My work style blends engineering depth with quality and leadership: I expanded test coverage using Playwright and Cypress, set up robust CI/CD and test pipelines, and actively mentored teammates on modern React hooks, performance improvements, and maintainable component design. Before Comet, I built fintech/crypto frontends (Boosty Labs), developed UK energy supply web solutions (N-iX), and delivered payment and gaming platform applications (ONSEO), including strong reliability through automated testing.
