Designing and delivering AI products for trust and growth

I build AI-native products that deliver business outcomes. My background includes product management, UX, and front-end engineering. I've led 0→1 at hypergrowth startups (Aurora Solar, FalconX) and delivered impact at scale for global brands (Samsung, Meta, Salesforce). My experience with AI/ML includes building explainable AI at Meta and leading NLP chatbot design for 20M Samsung users. Over the last year I've been solo-building full-stack AI products: LLM pipelines, HITL systems, evals, and CI/CD.

🔎 What I Build

I'm interested in:

• AI workflow design • Structured LLM pipelines • Growth instrumentation • Activation & retention systems • UX patterns for trust in AI • Evaluation frameworks for generative systems

My work emphasizes:

• Clear problem framing • Structured outputs over vague completions • Instrumentation before intuition • Guardrails and failure handling • Shipping fast with measurable iteration loops

🏗 How I Think About AI Product Systems

I view AI product development as four layers. Here's how I think about it in practice:

1. User Intent Layer — clarify job-to-be-done
2. Orchestration Layer — structured prompts + routing
3. Validation Layer — enforce schema, detect failure
4. Measurement Layer — track behavioral impact
