About

Frontend-focused engineer who built a full movie recommendation system from concept to production, comparing classic collaborative filtering with LLM-based recommendation approaches on AWS. Emphasizes scalable architecture, strict TypeScript data contracts, and high-quality Next.js/React UI patterns (defensive states, scoped state management, performance optimization) with disciplined QA and feature-flagged rollouts.

Key Strengths

  • Led an end-to-end production project with modular, scalable architecture (ingestion, model execution, evaluation layers)
  • Strong frontend architecture discipline: reusable components, separation of presentation vs data-fetching, defensive UI states
  • TypeScript-driven data modeling and stable API contracts to reduce runtime bugs
  • Pragmatic state management for multi-step workflows (local-first, lift when shared, Context to avoid prop drilling)
  • Frontend performance tuning via reduced re-renders and memoization
  • Structured delivery in fast-paced environments: incremental scope, staging QA with production-like data, feature-flagged rollouts, post-launch monitoring and iteration
