Work History
Software Architect
TIAA
11.2021 - 06.2024
- Worked on expanding existing frameworks and creating new ones as it made sense. Resulting in a sizable reduction in duplicated code.
- Helping to facilitate new code to follow a more event-driven architecture, as well as refactoring other systems to follow this paradigm.
- On the ground for new integration points with legacy and new applications.
- Ensuring we cover all the bases on data integrity and performance between them.
- Priority in regard to security.
- Conducted system architecture reviews and provided recommendations for improvements.
- Especially in regard to our ever-growing microservice landscape, and a diverse number of ways to communicate across those services.
- I mentored colleagues both on my team and off. Helping them build the best set of skills for moving forward in their careers, and always being there to help when needed.
- I performed interviews for junior, senior, and lead developers.
Lead Developer
TIAA
11.2016 - 11.2021
- Help effectuate change in our code review practices, ensuring better code readability, quality, and, hopefully, catching simple defects or performance issues that the code may introduce.
- I wrote a diagnostics microservice that would test as many integration points as possible, both internal and external, to ensure the system is fully functional.
- Mulesoft and OAuth/security integration framework
- Migration and refactoring to adhere to a microservice architecture.
- Worked on our automated testing suite to increase performance and decrease time.
- Reviewed code written by other developers to ensure quality assurance standards were met.
- Programmed applications and tools using object-oriented languages with goals of code abstraction, stability and reuse.
- I mentored colleagues both on my team and off
- I performed interviews for junior, senior, and lead developers.
Software Developer
TIAA/Envisage Information Systems
11.2012 - 11.2016
- Worked across a wide variety of technologies and designs, with the goal in mind to make the end-user experience seamless.
- I had interactions with the clients in a variety of different capacities.
- I built a dynamic HTML generation engine for a complicated page that had to be very diverse in how and what data was shown.
- The 'workflow' configuration was stored in the database and retrieved to build the underlying HTML.
- This was done in JSF using its framework to achieve the design.
- Worked on a skunk works project involving Natural Language Processing, whose sole point was to build up a repo of knowledge in the form of questions and answers, vetted by experts.
- Any 'new' question being asked would go through and run a comparison of the question to previous ones answered with a degree of confidence that it is answering the question to their satisfaction
- If not the user could ask for more info, and it would be kicked to an expert to clarify and make the system better
- (Mind you this was pre-mainstream AI, so I realize these things are significantly easier nowadays.)
- Worked on the security end of coding and testing
- Provided technical support for users of the software system.

Additional Information
- Frameworks related to versioning, locking, caching, security, Kafka and RabbitMQ to name a few.
- Fake OAuth2 server to be able to internally check that our side of the security coding works in a simulated environment.
- I was partially responsible for the technical questions. I also ran our practical coding exercise meant to see how people think about solving a problem.
- OAuth policies Both Authentication and Authorization as well as making sure certain HTTP headers are available and passed along the chain.
- We parallelized certain tests they weren't related or required by each other and analyzed and refactored our underlying framework to allow us to tweak the system for performance.

Accomplishments
- Two 1st place finishes in a CDX (Cyber Defense Exercise) competition with 5 to 7 other financial institutions. I was on the "Orange Team" as a developer to look for security flaws in a handful applications written in different languages. Then fix the code issues and tell the other members on my team how to go about exploiting the code issue.
