I build working software from one studio and ship it on naibl.ca. So far that means demand-driven concerts, a music workbench, karaoke, a free research lab for stocks, multiple dropshipping stores, — all on one account, all things I needed myself. I also consult on AI implementation and best practices and deliver 0 fee custom websites for clients.

Spearheaded the 0-1 launch of RainBarrel to deliver a privacy-compliant audience graph, scaling the engineering team from 2 to 7 while leading cross-functional alignment across engineering, design, and sales.

Additionally, drove market adoption by translating complex technical capabilities into customer-focused solutions at the North51 Conference.

Directed operations for over 200 associates, consistently hitting productivity targets to secure the #1 quality metrics across all North American fulfillment centers in 2020. Leveraged Python and AWS CloudWatch to build real-time analytics dashboards predicting a daily flow of 250,000 units, while driving process improvements that reduced incidents by 80% and saved $20,000 in monthly labor costs.

Developed and shipped Objective-C features for the Ericsson Indoor Planner iOS app, enabling critical 5G small sales. Designed and implemented robust test automation frameworks using Jenkins and Selenium, increasing overall web application reliability and deployment efficiency.
