Razvan Tomegea

• Own all web frontend for machine-vision sensor products as sole senior frontend engineer.
• Built React 3D engine for camera algorithms with real-time 10ms refresh and zero unnecessary re-renders during backend data subscriptions.
• Created foundational web SDK reused by other developers for sensor modules and web interfaces.
• Implemented region-of-interest drawing, camera result transformation, and algorithm pipeline (module/plugin) composition via web UI.
• Authored Playwright E2E tests for 3D engine and sensor modules.
• Continued migration from C++ (Qt) desktop UI to web-based sensor configuration tools.

• Owned Web wallet, browser extension, and framework-agnostic dApp SDKs (blockchain/Web3).
• Reduced extension bundle size ~30% via Vite tree-shaking, fallow, and dependency-cruiser.
• Merged wallet and extension codebases; achieved 90% test coverage with Jest and Puppeteer E2E.
• Cut CI test runtime to under 10 minutes; root-caused flaky tests across local and Ubuntu GitHub Actions environments.
• Created Angular, React, and Vue dApp starter templates for newest SDK release.
• Resolved community-reported edge-case bugs in wallet/extension (blockchain transaction corner cases).

• Built clinical research data repository (CMS) for Pfizer and Merck using Angular, Node.js/Express, PostgreSQL, and AWS.
• Solved mapping and transformation of clinical data via acyclic graphs; migrated from relational join tables to JSON graph storage for correctness and performance.
• Sole full-stack developer with full ownership of frontend and backend delivery.

• Pioneered company's first web application for sensor data visualization (React), replacing C++ desktop UI.
• Solved real-time camera data sync (10ms refresh) with TypeScript–C++ bridge, preventing browser crashes.
• POC adopted company-wide; enabled web-based configuration for all camera-equipped sensor products.
