About

Built an AI-powered job outreach application for his own job search and took it from idea to production use, owning architecture, FastAPI backend, retrieval/generation pipeline, frontend workflow, deployment, and iteration. Especially compelling for teams needing a pragmatic full-stack engineer who can turn LLM-based product ideas into usable, maintainable tools with measurable workflow impact.

Key Strengths

• Built and owned an AI web product end-to-end across frontend, backend, data, deployment, and maintenance
• Strong full-stack product engineering with FastAPI backend and lightweight web UI
• Applied hybrid retrieval and prompt refinement to improve LLM output quality
• Modular system design separating parsing, retrieval, and generation for maintainability
• Iterative, usage-driven product improvement based on real-world feedback
• Improved latency and user experience through async processing and reduced unnecessary backend work
• Designed structured API responses to better align frontend state with multi-step backend workflows
• Pragmatic testing approach focused on high-risk paths, unit tests, integration tests, and manual QA
• Strong debugging and production issue handling using validation, logging, and root-cause analysis
• Delivered measurable efficiency gains by reducing a 10–15 minute task to under a minute
• Built end-to-end full-stack loan approval workflow (React + Node/Express + Postgres) with KYC upload, reviewer dashboard, and JWT auth
• Scalability/performance engineering: Docker containerization, horizontal scaling with load balancing, Redis caching, and DB indexing/query optimization
• Real-time voice + LLM system design expertise (WebRTC/WebSockets gateway, streaming ASR/LLM/TTS, barge-in, stateless scaling, secure retention)
• Cross-functional collaboration with PM and support engineers to translate customer pain points into technical design
• Reduced empty request count by 84% (Amazon internship project)
