👋 Hey there! I’m David Tang.

As a Product Designer with a 🎓 Bachelor's in Computer Science and a Master’s in Human Computer Interaction, I occupy the rare space between engineering and design. I don't just advocate for the user; I understand the code, the database structures, and the technical constraints that power the experience.

My journey has taken me from providing enterprise technical support to architecting data-driven design strategies. Whether I am analyzing 10,000+ lines of unstructured data to extract user insights, leading 0 ➜ 1 product builds, or designing inclusive, accessible interfaces in Figma, my goal is always the same: to make the complex simple 👌.

When I step away from the screen, you’ll find me fueling up on coffee ☕, spending time with my wife 👧🏻, or reading to my 1-year-old 👶🏻 (his current favorite is The Three Billy Goats Gruff 🐐🐐🐐).

Key Achievements

• AI Anomaly Detection Agent: Led the end-to-end design for a financial monitoring agent in a 2-week sprint, defining the interaction model and building trust in AI through transparency.
  
  

• Enterprise Automation: Engineered a custom Python solution for the Pleasant Hill Police Department. Eliminated manual data entry, optimized evidence workflows, and secured 100% backup reliability.
  
  

• 'IRIS' AI Co-Pilot: Architected an In-Vehicle Infotainment System that outperformed competitors, boosting task completion speed by 34% and reducing user interaction cost (taps) by 51%.
  
  

• Full-Stack Prototyping: Engineered 'Responsibuddy' (Task Management) from 0 ➜ 1, using a modern stack (React, Supabase) to bridge the gap between high-fidelity UX and production-ready code.

What I Bring to the Table

• The Hybrid Advantage: With 5+ years of technical experience, I speak fluent "Developer 👨‍💻". I design 🖌️ solutions that are not only empathetic to the user but technically feasible for engineering teams.
  
  

• Data Visualization Expert: I specialize in translating abstract data models 📊 into decision-making tools for non-technical stakeholders, utilizing Python, Plotly, and Pandas.
  
  

• Strategic & Inclusive Design: From enterprise data governance to AI interaction models ✨, I build systems that prioritize long-term scalability, WCAG Accessibility, and security 🛡️.
