Виктор Руменов

I’m a Senior Frontend Engineer who builds reliable, fast product interfaces with React Native and TypeScript—then backs them up with automation, strict typing, and performance-focused engineering. I’ve co-led a small team and architected a React Native + TS + Redux framework that supports 60+ apps for 50k+ users.

Recently, I deployed a custom OTA system for instant JS updates, cutting production fix delivery time by 96%. I also optimized React Native FlatList rendering and filtering to eliminate UI gaps and memory leaks, so the experience stays smooth across real-world usage.

I’m also strong in shipping and maintainability: I led CodeMagic CI/CD automation, reducing manual release overhead by 92% with zero-downtime deploys. Earlier, I built React/TS frontend experiences like a merchant dashboard with a drag-and-drop page builder, integrated Shopify/Recharge REST APIs, and refactored legacy code for strict type safety using TypeScript and Zod verification.

Beyond core frontend, I’ve worked on backend-facing integrations and AI/RAG prototypes. In my projects, I built a PDF + YouTube RAG chatbot pipeline using Next.js, LangChain chunking, and Neon Postgres with pgvector (HNSW cosine indexes), streaming responses via Vercel AI SDK v6. I also developed an AI recipe generator with Gemini, tool/function calling, JWT-scoped security, and a containerized deployment workflow.
