💡 Did you know that most startups fail not because of bad ideas, but because of weak tech execution? In the past few years, I’ve helped founders in HealthTech, Real Estate Tech, and EdTech turn their early concepts into stable, scalable products that users love. Here’s what I’ve learned: 1️⃣ Simplicity beats complexity, especially in MVPs. 2️⃣ UX matters as much as backend logic. 3️⃣ Clear communication between devs and non-tech founders is game-changing. Curious to know, what’s the biggest challenge you’ve faced while turning an idea into a working product? #StartupTips #ProductDevelopment #FullStackDev #HealthTech #RealEstateTech #EdTech

Selling Buoy, so design drift doesn't ship

Cover image for Aloud started as an experiment

Aloud started as an experiment in generative pattern design and grew into a fully automated product business. I developed a repeatable art technique, built a Figma-to-Airtable pipeline that turned designs into live Shopify products in minutes, and scaled it through print-on-demand pocket tees. I later integrated NFTs on the Terra blockchain so digital ownership earned real royalties on physical sales, rebuilding the platform in React and working directly with smart-contract engineers. Over three years, I shipped daily designs, automated the entire design-to-commerce workflow, and ran the product end-to-end solo—from art and branding to Web3 architecture and fulfillment.

Cover image for As Design Systems Lead at

As Design Systems Lead at IXL Learning, I led the creation of a shared design system to unify five-plus products across a decades-old brand. I managed a team of designers, established a biweekly cadence for audits and reviews, and worked directly with product teams to ensure components were built for real production needs. Using atomic design principles and strong foundational tokens for color, spacing, and typography, we created a system that reduced drift, sped up delivery, and made new UI feel cohesive by default. The result was a living design system that teams actually adopted because it worked in practice, not just in theory.

Cover image for As Founding Designer at Zeal,

As Founding Designer at Zeal, I built the product’s UX and UI from zero, designing data tools that helped teachers make sense of student progress across Common Core standards. I spent multiple days per week in classrooms observing real use, during lessons, between classes, and in planning meetings, and redesigned based on what actually worked under time pressure. I led the design of teacher dashboards, proficiency heatmaps, goal-setting tools, and an adaptive classroom game that adjusted difficulty per student while maintaining shared competition. The result was a platform adopted by 100+ schools, where teachers could understand class progress in seconds and make better instructional decisions without wading through raw data.

Cover image for I led the end-to-end redesign

I led the end-to-end redesign of the FarmVille marketplace at Zynga, from early hand sketches through implementation. The goal was to modernize the UI while supporting seasonal reskins, flash sales, and an ever-growing set of monetization features without breaking usability. I designed the information architecture, wireframes, visual system, and a flexible skinning framework that allowed the market to be rethemed in days instead of weeks. I also designed the flash sale and promotion system, which drove major revenue spikes and was later adopted across other Zynga titles. The redesigned market ultimately supported a feature responsible for over $1B in revenue at peak scale.
