Viktor Dubnytskiy

I’m a Senior Front-End Developer with 9+ years building high-load, scalable web applications in React and TypeScript. I design and ship complete frontend architectures from scratch, often as the sole engineer owning architectural decisions end-to-end.

I specialize in performance and reliability: render optimization, complex state management with Redux and Zustand, and real-time data flows via WebSocket. Across data-heavy products, I’ve delivered measurable outcomes like 40% faster load times on financial dashboards and 60% fewer production bugs through form architecture overhaul.

In LegalTech and FinTech work, I’ve built secure, regulated-facing experiences—integrating Stripe KYC & Payments and implementing identity verification flows. I also delivered real-time video calling and document synchronization using Twilio WebRTC and WebSocket, enabling seamless remote sessions with zero-downtime state syncing.

I bring strong engineering discipline around maintainability and quality: CI/CD pipelines, reusable component libraries, and standardized code-quality practices. Whether it’s refactoring complex forms with React Hook Form and Zod or optimizing GraphQL schemas and queries, my focus stays on shipping faster, reducing regressions, and building systems teams can extend confidently.
