Growth. Leadership. Impact.

I joined Moment in 2018 as employee #20, starting as a full-stack engineer. Over seven years, I helped shape the company’s digital presence, modernized the platform, and guided a full replatform of our tech stack as Head of Software.

I’ve worn many hats: architect, builder, team lead, mentor, and decision-maker. This case study walks through the problems we faced, what I led, and the outcomes we achieved.


The Problems

  • When I arrived, the digital foundation was slowing growth.
  • monolithic Craft CMS limited iteration
  • AWS costs exceeded $9k per month
  • Conversion rates underperformed the brand
  • Engineers lacked a modern and fast frontend stack
  • No consistent tools for documentation or product planning
  • A growing iOS app with no supporting pipeline

The Work

1. Modernizing the Frontend (Years 1–4)

Focused on speed, clarity, and consistency.

  • Introduced Vue and Nuxt for faster builds and cleaner UI
  • Led UI/UX improvements that aligned our site with product quality
  • Built a team culture of ownership and iteration
  • Introduced Notion + project briefs that became team-wide standards
  • Mentored junior engineers/designers and built a culture of ownership

2. Replatforming the Stack (Years 5–7)

From a monolith to a modular, fast, developer-friendly system.

  • Migrated from Craft CMS to Next.js + Sanity CMS + Vercel + Shopify
  • Cut infrastructure costs by 50 percent
  • Improved Core Web Vitals to all “Good”
  • Unified frontend and backend with React and GraphQL
  • Enabled the marketing team to launch campaigns independently
  • Introduced bundles that increased average order value by 175%
  • Have launched multiple products - travel, digital goods, courses, kits
  • Designed and built a majority of features in the browser

3. Moment Pro Camera

iOS at scale — then a ground-up rebuild as product lead.

Moment Pro Camera II at #1 on the iOS App Store Paid charts
Moment Pro Camera II ranked #1 in Paid Camera apps
  • Led Moment Pro Camera engineering: App Store compliance, release cadence, and roadmap — tight loops with design and product while the app held a Top 3 Paid spot
  • As the product matured, the next bet was a full rebuild: Moment Pro Camera II — new interaction model, new codebase, and since launch #1 paid Camera app on iOS (I led product and design on that chapter)

The Results

  • Conversion Rate: 0.9% → 2.5%
  • Average Order Value (AOV): +$50 baseline
  • AOV w/ Bundles: +175%
  • Infra Costs: -50%
  • Core Web Vitals: All "Good"
  • Moment Pro Camera: #1 paid Camera app on iOS (MPC II); earlier releases sustained Top 3 Paid

Reflection

What I’ve realized I enjoy most is making a product, brand, and team better. Iterating deliberately, defining processes and systems that others can build on, and elevating design and UX in tangible ways that have impact and legacy. It’s about leaving a product in a stronger, smarter, more thoughtful place than I found it.

I've also learned the importance of fusing my creative background with business and growth thinking which has made my decisions smarter, faster, and more outcome-driven.
