Building Katana

I'm currently building Katana, a tool to help content creators make polished, professional video content without ever using an editor. I previously led the AI team at Hopin. Formerly CEO/co-founder of Vectorly (acquired by Hopin). US Patent Holder, Fluent in Mandarin and Spanish

Work Experience

Katana

Remote
CEO / Founder
2024 - Present

Building Katana, a tool to help content creators turn podcasts and webinars into short clips they can reuse on social media

Hopin

Remote
Head of AI
2021 - 2024

I lead the AI team at Hopin, building features like AI Upscaling and Touch Up in Hopin's livestreaming product. I do both product (talking to customers, strategy, project management) and engineering (training AI models, prototyping features).

Vectorly

San Francisco
CEO / Co-Founder
2018 - 2021

We developed and patented a novel video-compression technology called "Video Vectorization" which could compress animated & e-learning video by 10x (compared to h264) while improving video quality. We found it difficult to commercialize our new video codec and pivoted to AI Media Processing (e.g. AI Upscaling, Noise Filtering) in 2020.

Our AI Media Processing SDK was 10x more efficient than anything else available at the time, and was used in production by a number of billion-dollar companies, including Hopin, Fuze, Airmeet and Hubilo. In late 2021, we sold Vectorly to Hopin, our largest customer.

dot Learn

Lagos, Nigeria
CEO / Co-Founder
2016 - 2018

After graduating MIT, I started dot Learn as a social-impact venture, building an e-learning app with affordable, data-light video-learning courses which helped 50k+ students in West Africa study for their college entrance exams.

After failing to monetize, we rebranded the company to "Vectorly" in 2018 and focused on commercializing a proprietary video-compression algorithm "Video Vectorization" we had built internally.

Professional Skills

Top Skills

98%

AI & Neural Networks

Expert, 8 years
Several research papers & a master's thesis in AI. Developed custom NLP models (BERT Classifiers, GPT models) as well as Computer Vision models (Super Resolution, Image Segmentation and Image classification) for various AI features at Hopin.

Product Management

Advanced, 4 years
I previously ran my own company Vectorly. Our AI Media Processing SDK went from 0 to $20k MRR in 3 months of launch, and the product was good enough that we were acquired by one of our customers (Hopin). At Hopin, I launched several features including Touch Up, Background Noise Removal, which are each used by ~100k Monthly active users.
