Mohamed Amine Hajltaief

About

Frontend/full-stack engineer (~5 years) who led large-scale React + TypeScript products including a Shutterstock-like media platform with private, invite-based content and SSO-style auth redirection. Strong in performance for media-heavy experiences (thumbnails, CDN, caching, chunking) and in quality systems (Vitest, E2E, CI gates, QA/staging). Also built a complex Figma/PowerPoint-like editor with custom state management and undo/redo history tracking.

Key Strengths

• End-to-end frontend architecture setup (routing structure, auth flows, shared state, reusable modules)
• Performance optimization for media-heavy apps (thumbnails WebP/WebM, CDN, caching, chunked loading)
• Quality-focused engineering with strong automated testing (Vitest unit + snapshot, E2E/integration) and PR quality gates
• Built complex React/TypeScript editor with custom undo/redo history system and re-render minimization via state separation
• Pragmatic codebase improvement: balances performance, readability, and reusability (including de-generalizing overly complex shared components)
• Fast-paced feature delivery using type-first development and synthetic data generation to cover edge cases early
