PrintShop is my all-time favorite consumer experience we brought to life at MakerBot. As the company pushed 3D printing into the consumer market with the new Mini Printer, we developed an end-to-end iPad app that made 3D printing accessible to everyone. Users could browse top models from Thingiverse, customize wearables, and purchase high-quality models from our digital store—all without any modeling skills required. The icing on the cake was Shape Maker, a feature that let anyone draw on paper, snap a photo, and transform it into a 3D model. Check out the video featured on my profile to see it in action.

In terms of social impact, Hero helped members live their best lives by ensuring they took their medication on time. I joined the company to design and develop the consumer experience from end-to-end with a tight-knit team right from the start. We focused on two key sprints: Setup: Onboarding accounts, setting up schedules, and loading the medication dispenser with pills. Day-to-day usage: How members get notified when it's pill time, dispensing meds, and what happens if they miss a dose—cue the caregiver experience. Incredibly complex digital/physical interactions made simple. Sometimes when you're grinding, you don't realize the impact until a member reaches out and says: "I want to say how this machine has changed my life! Because of Hero I've not had a seizure in months."

My last startup was a truly groundbreaking hardware/software experience. Canary Medical engineered a smart implant device that allowed Healthcare Professionals (HCPs) to monitor patient recovery progress following knee replacement surgery. I led the overhaul of the HCP platform design and the execution of a patient app that let individuals view their own recovery progress. This included improvements to the base station setup experience, plus AI-assisted data analysis and exercise recommendations.

Alright, here we go. I've been working solo on v2.0 of my personal iPad app for inspiration and daily organization called SuperStash. Using Figma MCP, Cursor, and Claude Sonnet 4.5, I'm currently beta testing to finalize before launch. It's an infinite canvas tool (draw anywhere with Apple Pencil) that includes a built-in web browser with preloaded inspiration sites. Save images to the canvas, organize them, and share. Stay on top of your to-do list (syncs with Reminders) with built-in widgets and a Pomodoro timer. If you're interested in testing, please DM me and I'll send you an invite. Just getting started with Contra, so any helpful hints would be great too!

Cover image for DIEM was a multi-year health

DIEM was a multi-year health and wellness technology project I developed from concept through a working mobile platform. The goal was to combine nutrition, fitness, lifestyle and community into a personalized daily experience built around each user’s goals, activity level, health considerations and preferences. My role went far beyond the app screens. I was involved in product strategy, business model development, UX and feature planning, professional health-content development, personalization logic, reporting, database structure, developer coordination, testing and marketing. DIEM included personalized daily to-dos, nutrition and exercise tracking, health profiles, goals, reports and tools designed to make complex wellness information practical and usable. This project represents the way I approach technology today: start with the real user and business need, define how the experience should work, then build the technology around it.

Cover image for DIEM — Health & Wellness

DIEM — Health & Wellness App Product Development I founded and led the development of DIEM, a multi-year health and wellness platform designed to bring nutrition, fitness, lifestyle guidance and personalized wellness information together in one experience. The idea was to go beyond a basic calorie tracker or workout app. DIEM was designed to understand the individual user—their goals, activity level, nutrition, health conditions, allergies and other profile information—and use that data to provide more relevant daily guidance. My role covered virtually every part of the product and business development process. I worked closely with professional software developers to define features, workflows, functionality, user experience, testing requirements and ongoing improvements. The developers handled the programming, while I directed what the platform needed to do and how the overall system should work. I also hired and worked with licensed dietitians, physicians and other health professionals to develop the wellness information behind the platform. That content was incorporated into formulas, rules and logic designed to provide personalized recommendations to users. DIEM included features such as personalized daily regimen items, nutrition tracking, exercise tracking, health conditions, allergies, goals, reports and wellness recommendations. Users could select goals such as losing weight, getting fit, improving overall health, toning, gaining weight or maintaining their current condition. The platform was also designed with a professional side in mind, allowing trainers, coaches and health professionals to eventually review user information, provide guidance and work more closely with their clients. Beyond the product itself, I was involved in branding, competitive research, UX direction, content development, marketing, social media, business strategy and commercialization. The larger business model included consumer subscriptions, professional accounts, corporate wellness programs and potential white-label licensing. DIEM was a substantial multi-year product-development project that brought together technology, professional wellness content, user experience and business strategy. It demonstrates my ability to take a complex idea, define how it should work, coordinate the right specialists, and develop it into a structured product with a clear path toward commercialization.

Cover image for StreamStash: Streamline Finances for Digital Creators

StreamStash is a fintech platform built for digital creators — musicians, streamers, vloggers, influencers, and online entrepreneurs — to organize, track, and access their earnings across multiple platforms in one place. The idea behind StreamStash is simple: Creators today make money from many different sources: Streaming revenue Brand deals YouTube monetization TikTok payouts Affiliate income Merchandise sales Donations and subscriptions Sponsorships But all of those payments arrive at different times, on different platforms, with different payout rules. StreamStash acts like a financial command center for creators. What It Does Unified Creator Dashboard Creators can connect multiple income platforms and view: Total earnings Pending payouts Monthly revenue trends Platform performance Estimated future income Faster Access to Earnings One of the platform’s goals is reducing the long wait creators face before getting paid. StreamStash is designed to support: Instant payouts Early payout access Revenue advances Flexible withdrawal systems Especially for independent creators who rely on consistent cash flow. AI Financial Assistant A future-facing part of StreamStash is AI-powered creator finance support. The AI layer could: Forecast upcoming income Analyze spending patterns Suggest budgeting strategies Predict slow revenue periods Recommend growth opportunities Help creators understand taxes and business finances Not replacing accountants — more like giving creators a smart financial operations assistant. Why It Matters Most creator tools focus on content creation. StreamStash focuses on the business side of being a creator. That matters because a lot of talented creators: don’t understand cash flow, get paid inconsistently, struggle with taxes, or can’t scale because their finances are fragmented. StreamStash aims to make creators feel less like freelancers surviving month-to-month and more like actual digital businesses. Positioning The platform sits somewhere between: creator economy tools, digital banking, creator analytics, and fintech infrastructure. Think: “Plaid + Stripe + creator analytics + AI finance copilot for creators.” And frankly, the creator economy still has a giant hole here. Everybody wants creators to make content. Very few companies are helping creators build financial stability.
