Extracker is a cost communication platform. As the lead front-end developer, I played a key role in the greenfield rewrite of the application. To accomplish this, I collaborated with a back-end developer to migrate the preexisting PHP application to a React and Node.js stack.

Beautiful, fast, and modern front end for the most ambitious Shopify brands.

An eCommerce builder developed with NextJS to provide Shopify brands with a unique and branded website they can easily update with no code needed.


Megatrans is a real-time distributed fleet management system implemented with a microservices architecture. As a full-stack engineer, I worked both on creating microservices to implement business logic and front-end applications to interact with different aspects of the platform. One of the most gratifying and challenging tasks was the implementation of a map to track the fleet in real-time.
A no-code platform to create automation with a strong focus on Web3. The back end is coded in Python. We used Next.js for the front end and have on-chain through a bespoke delegation contract that allows our users to automate on-chain actions on Ethereum and Polygon.
