Developer Spotlight: Robert Perona, Staff Engineer at Ellie Mae

Hi blog readers! I’m happy to announce that beginning today, I’ll regularly share stories – right here on our developer blog – about developers who are creating some amazing integrations using DocuSign APIs. Our DocuSign Developer Spotlights highlight the plethora of industries and companies that use our APIs, as well as the varied use-cases they support. For this first post, I’m beginning with Robert Perona from Ellie Mae.

Robert is a Staff Engineer with the Document Platform team at Ellie Mae, a software company that processes 35% of mortgage applications in the United States. A self-trained software developer who started his professional career automating business processes at retail companies, Robert joined Ellie Mae almost three years ago as a Software Engineer. Today he works primarily on the secure document delivery system behind Ellie Mae’s Encompass Lending Platform, which uses the DocuSign eSignature REST API to provide signing functionality in conjunction with Connect Webhooks to provide near real-time updates to Ellie Mae customers, trigger notifications, and load data based on recipient signing. According to Robert, “The comprehensive APIs have been great in allowing us to optimize the creation process using multi-part requests and streaming posts for envelope creation.”

Also of great importance to Ellie Mae’s integration is DocuSign’s comprehensive audit information, which it leverages for compliance tracking and integrations as evidence. Robert has worked closely with the DocuSign API team and has seen his feedback integrated in each iteration of the documentation, which has quickly evolved into a robust source of information where he rarely has to ask additional questions.

In his free time, Robert enjoys ice skating, playing games with his family or on the Nintendo Switch, playing volleyball with his teammates, learning new things about physics and science (currently quantum computing, and (or course) coding. You can find him on LinkedIn.

If you have deployed solutions using the DocuSign eSignature API and you’d like to be considered for a future Developer Spotlight, please send me an email to with information about your solution and a bio.
