Work Experience
Principal
Bamboo Software, LLC
- Developed and launched a greenfield cloud-native web application from scratch using Angular and .NET Core, hosted on Azure, using GitHub Actions for CI/CD, while guiding the client through the development lifecycle in a project management capacity.
- Architected a lean microservice solution using .NET Core and Google Cloud Functions to analyze stale products in the client's Shopify store.
- Designed and implemented a new microservice process and internal tool for the client to integrate, manage, and track their Just-In-Time inventory system with their largest customer, integrating with the client's legacy ASP.NET Web Forms solution.
- Created and implemented a language-agnostic centralized CI/CD system for several old and modern projects, using GitHub Actions for automated builds and tests and Octopus for managing deployed versions and rollbacks.
Software Developer
New Innovations, Inc
- Implemented the team's first .NET Core Web API with an Angular front end, simultaneously introducing the team to automated unit testing at both the back-end API and front-end UI.
- Spearheaded an initiative to migrate legacy code via domain-driven design principles away from the legacy transaction script architecture, leading event storming sessions to begin modeling the domain.
- Embedded Angular Elements into legacy Web Forms pages to begin migrating away from old technology with minimal impact on the current system.
Quantitative Strategist | Developer of Operations and Post-trade Technology
BlueMountain Capital Management, LLC
- Implemented support for new asset classes (mortgage TBAs and bond futures) in our proprietary domain model using DDD and event-sourcing.
- Revamped the firm's fund accounting NAV and returns data system, backed by extensive regression tests, to decommission a number of legacy spreadsheets by converting them into first-class C#, AngularJS, or SQL applications.
- Developed an internal trade/position automated reconciliation report that reconciles the universe of the firm’s trades and positions to a separate querying database to ensure adequate consistency at a point in time with a given time lag threshold.
- Automated a number of formerly manual monthly, quarterly, and annual reports while building out an API that would later prove useful for other teams and reports.
Associate Developer (Asset Backed Securities)
Societe Generale
- Developed and deployed a REST ASP.NET Web API to serve as the team’s primary data source, using SQL, Unity Dependency Injection, NUnit/NSubstitute, Swagger, IIS, and TeamCity.
- Designed and developed a user-authorization system for the team’s web-based systems using C#, SQL, ASP.NET, Angular, Bootstrap, Swagger, IIS, and TeamCity, which was the first Angular project for the team.
- Developed a web-based monitor and manager of all the team’s automated data integration processes using Node.js on the back end and AngularJS for the UI.
- Created a report generation framework in C# and Bootstrap to standardize the reports that the team sent internally and externally on a daily basis.
Associate (Structured Products Marketing)
Societe Generale
- Developed marketing slide-decks, brochures, and other documents describing exotic derivatives products covering multiple asset classes, including Equities, Fixed Income, Forex, Volatility, TRS, and Credit.
- Maintained a large repository of marketing communications, following strict requirements to obtain and manage Series 3/4/24 approvals, as well as Legal & Compliance approvals where necessary.
- Developed tooling for Excel and PowerPoint via VBA to automate aspects of the approval processes for marketing documents.
- Developed tooling for Excel and PowerPoint via VBA to automate aspects of updating large data-heavy slide-decks and other marketing materials.
- Created automated template files for legal and sales departments to use to generate pre-approved marketing materials for certain medium-volume processes.
Experience
.NET Field Level Encryption Extension for Newtonsoft and Utf8Json
https://github.com/Burwin/JsonCryptionETL Process on Shopify's API using .NET Core and Google Cloud Functions
Just-in-time Inventory Management Integrated with SAP
- Multiple jobs that run periodically (every few minutes or once per day)
- Some jobs poll internal SharePoint locations for new XML files to ingest (purchase orders, shipment receipts, client inventory levels, etc.)
- Some jobs check internal data models for business objects that need to be turned into XML files to distribute back to the client (advanced shipment notifications, order confirmations, etc.)
- Custom web views were created for internal users to manage various parts of the process, using the client's existing ASP.NET WebForms solution and adding bootstrap styling for a better user experience
- Created a CLI to be used by internal power users to run for special cases, which were ultimately used to trigger the jobs themselves
CI/CD Pipeline Framework for Multiple Project Types
The pipeline was completed with significantly reduced deployment errors, more joy for the developers, and much greater developer efficiency and deployment frequency.
HallPass.dev
The project also has a lightweight web portal for registering for the free trial. The web portal uses Vue3 with TailwindCSS for the front end and NestJS and TypeScript for the back end.
Finally, to perform adequate load testing, I designed and deployed a simple rate-limited API using NGINX deployed to a standalone Google Cloud VM, explained here: https://github.com/BambooSoftwareLLC/ratelimited.dev.
