Experience

Clak.me

https://clak.me

Clak.me is a link in the bio website builder. It's an iOS app (Android coming soon) that lets you create a simple website with all your important links in one place. It also lets you sell digital products and get paid and offers analytics. It is VC funded by Village Global and Unusual Ventures.

I served as CTO of Clak and was personally responsible for coding a lot of the technology components of the app, the APIs, the website, and the infrastructure.

Blink API

Built an API that allows developers to quickly prototype and deploy production-ready cloud functions with no credit card required. Ideal use cases include building chatbots, cron jobs, or any other cloud function. It also offers persistent storage and the ability to schedule functions.

Tavaga

https://tavaga.com

Tavaga is a robo-advisory app for personal investing. I led the team that created the entire product, including the APIs built on Node.js, the infrastructure on AWS, and the mobile apps built using Java with Android and Swift with iOS. The app received a positive response on launch and is currently used by thousands of users for their investment needs.

The app has remained pretty much unchanged since I created it back in 2015.
