Work Experience
Back-end Developer
Countifi (via Toptal)
- Planned and created the main API using AWS Lambda for high availability, Node.js to make it easier for other developers to help in the project, and MongoDB because it allowed us to quickly change the data structure as needed for each use case.
- Created a secondary API that runs over AWS EC2 to host processes that run for a few seconds and work on large datasets.
- Wrote services that run on Raspberry Pi devices installed in warehouses. The services are designed to be reliable without any human intervention and written in Go for reliability and ease of deployment.
