Backend Software Engineer - Pex (June 2022 - Now)
Golang Developer, Backend Systems (June 2022 - Now)
Currently a member of the backend developer team working on improving systems that serve different products at Pex
Software Engineer - Mile Two (2020 - May 2022)
Golang Developer, Command-Line Dev Tools (March 2021 – May 2022)
As a member of a the data team, I worked on improve the data workflow of AI/ML engineers. The data command-line tool helps AI/ML engineers, and data scientists with data versioning, management and cloud transfer. The data is tracked locally, and transferred data in a docker registry for efficiency.
My first project on the team was to developed a way to record and visualize the tool’s CPU usage and memory consumption. I used Python (psutils) to capture the app's metrics, and create visualizations using Dash with Plotly for the results.
Later, I added the capability for the tool to give line specific feedback when users mistakenly adds invalid entry to configuration files (yaml, and json).
Currently, I am working on a tool to generate test datasets to exercises the features of the data catalog (an internal data sharing platform).
C++ Developer, Adobe Plugin (Jan 2020 – Feb 2021)
For my first project as a full-time developer, I created a prototype plug-in for Adobe Acrobat to increase the productivity of analysts processing redactions for multiple FOIA (Freedom of Information Act) requests.
Analysts process dozens of large PDF documents a week, and wet (ink) signatures require them to comb through a document page by page to redact them. I worked on a prototype application that enabled a set of features that would speed up their workflow. The notable features of the app are:
- Automated search of wet signatures within a PDF, previously a manual process, using OpenCV.
- A flexible redaction label manager. Instead of only applying one label to one redaction, the analyst can set labels to redaction in a one-to-one, one-to-many, many-to-one, and many-to-many in a single step.
While trying to achieve those results, I encountered a few problems. One of them was that signature lines led to many false negatives. So, I added a preprocessing layer to remove the lines before the search. The added layer reduced false negatives in search results by over 90% in cases where lines were present in the original selection. I also updated the app's architecture from single to multithreaded (along with the necessary data structures), which improved app UI responsiveness by pushing heavy computation to separate worker threads.
I led product sprint planning sessions by contributing issues and scoping features to implement within sprints.
Tools: C++11, Acrobat SDK, Visual Studio 2019, CMake
Aviation Systems & Electronic Hardware Engineer - GE Aviation (2014 - 2019)
Electronic Hardware Test Engineer (Jan 2018 – 2019)
I designed, built, and tested an electromagnetic interference tolerant interface box using optical isolators and fiber-optic cables. The interface was used to obtain data for Federal Aviation Administration qualification procedures for the hardware we built. I also wrote and executed test procedures for the qualification of flight-ready electronic hardware and designed printed circuit board test adapters using Altium Designer to facilitate test procedures.
Avionics Systems Engineer, Power Conversion (July 2015 – Dec 2017)
I researched, analyzed, and validated the protections devices we used on various circuits for the hardware we were producing at the time (Note: for the curious, look up transient suppression diodes). I used MATLAB to compute energy absorbed by the device and accounted for environmental factors such as temperature and altitude. I also analyzed the impact of a lightning strike on aircraft electrical sub-circuits.
I also wrote and managed the hardware requirements document for the 777X Backup Electrical Power System (BEPS) converter using DOORS.
Avionics Systems Engineer, Aircraft Health Data (Aug 2014 – July 2015)
I wrote and reviewed requirements for the aircraft health management unit. I also developed and executed test procedures for the aircraft health management unit.
