The Underdog Who Outsmarted 60+ PhDs

“I contracted for OpenAI, a mere bachelor against 60+ PhDs across various fields. And the Underdog always came out on top.”

Design System

Enterprise‑ready tokens & components

Refactored a multi‑product design system with semantic tokens, usage docs, and high‑performance primitives. Faster delivery, fewer regressions.

AI Product

Human‑in‑the‑loop AI workflows

Built opinionated UX for LLM features: inline prompting, eval loops, and guardrails. Clear feedback ensures trust and measurable wins.

Frontend

Motion that sells, not distracts

Frictions smoothed with micro‑interactions and scroll reveals tuned for performance. Always respectful of reduced‑motion preferences.

Skills execs crave most

Strategy‑to‑shipping coverage: I bridge product, design, and engineering so your roadmap moves without stalls.

Applied AI & Prototyping

Translate ambiguous AI ideas into validated, demo‑worthy experiences. Rapid spikes, measurable outcomes, and pragmatic scope control.

Design Systems & UX

Accessible components, scale‑proof patterns, and documentation leaders love. Opinionated defaults—easy to adopt, hard to misuse.

Frontend Engineering

React, Vite, Tailwind, Framer Motion. Production‑ready performance budgets, code reviews, and CI discipline.

Product Strategy

Clarify positioning and narrative. Tie every feature to a business lever—activation, retention, conversion, or ops efficiency.

Data Fluency

Work with data teams to define metrics, build dashboards, and wire feedback loops into the product.

Executive Communication

Concise memos, crisp demos, and visible progress. I keep leadership informed and confident.

Experience that outperforms expectations
