About

Full-stack engineer who shipped and owned a production Document Chat feature built with Next.js App Router/TypeScript and a Node/Express RAG backend, including JWT-secured route handlers and streaming responses. Demonstrated strong post-launch ownership by improving latency (~30%) via MongoDB indexing/query optimization and reducing AI costs through caching, backed by profiling with React Profiler and Chrome DevTools.

Key Strengths

• Shipped end-to-end Document Chat feature in production with Next.js App Router + TypeScript and Node/Express RAG backend
• Designed secure server-side data loading with Server Components and interactive chat via Client Components
• Implemented JWT validation and backend proxying via Next.js route handlers, including streaming responses
• Post-launch ownership: monitored latency/DB performance and improved observability via better error logging
• Reduced response times ~30% by adding MongoDB indexes and optimizing aggregation queries as data volume grew
• Lowered infra cost by caching to reduce redundant AI/embedding lookups
• Frontend performance optimization using React Profiler/Chrome DevTools; improved perceived latency ~30% with streaming + message list rendering optimizations
• Built durable multi-step ingestion workflow with idempotent state tracking, retries (exponential backoff), and safeguards against duplicates
