Managing Pay with PayPal, Pay with Venmo, and Digital Wallets teams.

Tech lead for wallet integrations. I build and maintain backend integrations for PayPal, Apple Pay, Google Pay, Venmo Pay.Mostly Ruby on Rails, with occasional forays in Java, iOS, Android, and Javascript.

I helped build the Climate iOS app from (almost) Day 1.As a part of the Climate Basic team, I published an open-source library for building animated map overlays, designed how to decompose the app into separate modules using Cocoapods, and delivered features like future radar, push notifications, and scouting pins.

● Enabled end users to securely upload DICOM portable media to cloud servers via HTTPS with a ClickOnce­-deployed WPF application that preprocessed images and reports to minimize back­end processing time and resources● Created multithreaded back­end service to provide concurrent processing of DICOM data uploaded to cloud servers● Decreased DICOMDIR creation time by up to 50% by creating C# plug­in DLLs to augment product’s legacy code, which eliminated a performance bottleneck, enabled support for larger jobs, and prevented a major code rewrite● Designed and implemented a feature to synchronize user account credentials between multiple networked devices, which helped reduce support call volume and streamlined the account administration process

● Eliminated most incidences of database corruption on the PacsCube by creating an automated database maintenance and repair service written in C#, which drastically reduced a frequent cause of support calls● Overhauled the product’s configuration backup/migration process by porting 20k+ lines of VB6 spaghetti code to C#, which reduced backup sizes by up to 90% and eliminated● Improved RMA turnaround times by automating many parts of the build process with command­line utilities● Created a support training program and internal support wiki
