Portfolio

I’ve been building software and shipping products for over 20 years. From ocean prediction systems for the Canadian Coast Guard to running a $2M/yr beverage company with just 2 people, I’ve worked across the full spectrum – mobile apps, web platforms, e-commerce, AI automation, open source, and physical products.

Here’s the highlight reel.

Psychedelic Water, 2021-Present

Companies I’ve Built

Psychedelic Water

Co-Founder & President | 2021-Present

Functional beverage company selling online and at retail across the USA. I built the Shopify store, run the Amazon channel, and manage every technical integration – sales, marketing, CRO, analytics, subscriptions. $2M/yr in revenue, operated by 2 people. That only works because I’ve automated everything I can: order consolidation across 6 sales channels, ETL pipelines with Apache Airflow, inventory forecasting, and AI-assisted email marketing.

Women’s Pro Baseball League (WPBL)

EVP | 2024-Present

One of the initial team members bringing professional-level baseball to women. I launched the website, set up social media, run the e-commerce store, designed the initial logo, and built the tech stack for live-streaming events. Custom tools for inventory monitoring and financial reporting. Built custom WordPress Gutenberg blocks for draft picks, player profiles, and video stories. Flutter mobile app for schedules and player data.

Pro Padel League

IT Lead | 2023-Present

The premier padel league in North America. Built the original website, managed the team that rebuilt it, then brought it back in-house. I run email marketing, set technology guidelines for team franchises, and handle YouTube live streaming during events.

Programmatic Content Platform (~2012)

A platform that managed hundreds of WordPress sites across a network of servers, populating them with content at scale. Had paying clients within days of launch. Google’s Penguin update wiped out the entire category overnight. I’ve revisited this idea multiple times as the tech improved – most recently with an AI-powered version using ChatGPT that generated real traffic across several WordPress sites including Kavakis.com.
