Backend Engineer

Percolate (now part of Seismic)

Feb 2015 - Apr 2019 (4 years 3 months)

* Backend engineer responsible for building and maintaining client-facing APIs backed by a distributed backend architecture (a mix of Python/Django, SQL, Elasticsearch, Kafka, Neo4j graph database, microservices etc.). * Led development on a project that will leverage a graph database for object-level access checks by representing Percolate's entire object hierarchy as a graph and querying against it instead of querying multiple SQL datastores. This will bring down the time required for access checks down from up to 500 ms to less than 50 ms - an improvement of more than 90%. Show less

* Built a backend JSON API using GeoDjango/Tastypie for MetPetDB, a web application which is used by a global team of metamorphic petrology researchers to store and manage their database of rock samples. * Reduced API response times by almost 80\% by patching Tastypie to optionally accept a list of database fields to retrieve during a GET request and ignore the rest. * Implemented authorization and authentication logic on the backend to limit unauthorized access to data.
