Tan N.
Senior Full-Stack Engineer | AI Solutions & Performance Architecture
Most developers ship features that create technical debt. I engineer high-performance, scalable systems designed for long-term business growth. With over 2,600+ hours of proven delivery on Upwork and a CS degree, I don't just write code, I architect solutions that stay stable as you scale. WHY CLIENTS PARTNER WITH ME I specialize in taking complex, "messy" requirements and turning them into production-hardened infrastructure. My track record includes: AI PIPELINE ORCHESTRATION: I build sophisticated LLM workflows (Gemini, OpenAI) that solve real-world logic problems. My AI Market Intelligence Engine uses weighted similarity and outlier detection for precision pricing. PERFORMANCE ENGINEERING: I recently overhauled a D3.js rendering engine, achieving a 200% performance increase for high-density data visualizations. ENTERPRISE RELIABILITY: I have managed multiple 500+ and 900+ hour contracts, proving my ability to maintain deep codebase ownership and provide consistent, long-term value to growing teams. TECHNICAL ECOSYSTEM Frontend: Next.js, React, Tailwind (High-fidelity, performant UIs) Backend: Supabase, PostgreSQL, Node.js (Scalable, secure infrastructure) Intelligence: Gemini, GPT, Multi-stage AI Pipelines, Context Caching Infrastructure: Netlify Serverless, AWS, Firebase THE COMMITMENT I am not just a "task-runner." I am a technical partner who prioritizes clean architecture, daily transparency, and measurable performance. Let’s build something solid. Send me a message to discuss your system architecture.
