I’ve been working as a software developer for over 15 years, and have a strong interest in database technology.<\/p>\n
At each job I’ve held, I’ve done significant performance tuning efforts and worked on both OLAP and data warehouses in both Oracle and Postgres.<\/p>\n

Wingspan, an IQVIA Company: Life sciences Platform<\/b>
\nI’ve worked on many projects over 10 years at Wingspan. I built a data warehousing and reporting system for a Life Sciences product for a top tier Pharma, using an Oracle database.<\/p>\n
I helped migrate this application to a self-hosted SaaS product on Postgres.<\/p>\n
I made major contributions to the data architecture of the product around auditing, and invented a way to dramatically improve the scalability of ACLs using techniques based on compression.<\/p>\n
I introduced Docker to the company – writing scripts to snapshot and reconstruct internal environments.<\/p>\n
I did the backend research to add full text indexing to our Postgres database and to the processes used to index data to Solr.<\/p>\n
