Co-Founder, VP of Software
A Health Tech startup that manufactures devices that measure the quality of the environment and stream that data to the cloud. The data is presented to users with two products:
- A monitor installed in ICUs shows real-time information and is powered by a Flutter app running on a Raspberry PI
- A mobile app and website that extends the above and allows managers to get complete reports and insights.
- Defined the architecture of frontend and backend applications
- Guided team on following best practices
- Implemented first versions of the monitor and the backend
- Implemented lambda functions for data analysis using Python and Pandas
Senior Mobile Engineer
The UK’s leading innovator in smart EV charging. They manufacture EV chargers and provide a companion app for customers to monitor and control their devices. Their app had a serious problem keeping its state in sync with the server. That meant, for instance, that the app would show the charger idled when it was being used and vice-versa. Lucas was brought in to help solve the problem.
- Analyzed the entire codebase and found problems with the architecture
- Wrote an architectural proposal and oversaw the initial phase of development
- Implemented a new package for managing web socket communication. This package had features like an automatic reconnection, Internet awareness, and backoff strategy, besides following the json rpc protocol correctly

- Single-handedly implemented CI/CD pipelines, using GithubActions and Fastlane, that resulted in weekly releases and, therefore faster time-to-market for features and bug fixes
- Mentored junior developers regarding code quality and the importance of unit tests
