Technologies: Ruby, Rust, PostgreSQL
- Created an interface between FleetBoard and Salesforce for a large logistics company. Trucks in the field receive work orders as part of a manipulation that the back-office starts in Salesforce. Once completed, results flow back into Salesforce and allow for up to date reports on the company.
- Created an API to a database containing several years of unihockey player and play data. The API provides almost real-time access to summaries and statistics. An inflow of data triggers hooks, which in turn, trigger re-computation of statistics within only a few seconds of the original event. This way, tables of results stay up to date while still allowing for frequent page impressions during matches.
- Created and maintained several open source projects such as 'parslet' (Ruby) or 'bocuse' (Ruby). Parslet is a parser generator library that allows for writing parsers quickly. My focus was on legibility of error messages when the parse fails.
- Deployed software and microservices on server infrastructure, including storage and redundancy. Services deployed here include PostgresSQL HA, HAProxy, Linux Pacemaker + Heartbeat, and iSCSI ZFS ZVOLs.
