- Designed and built a distributed system of services in Rust that is used to generate business critical manufacturing insights about 3D CAD files. The system coordinates different services and resources to perform file conversions and computational geometry operations.- Worked closely with DevOps team to provision service infrastructure in AWS using Terraform.- Rearchitected job processing system to use AWS SQS to process jobs asynchronously and remove high volume of HTTP request time-outs.- Benchmarked Rust computational geometry code to identify performance bottlenecks. Refactored and optimized our medial axis algorithm implementation to exploit parallelism and reduce runtime by more than 70\%. - Wrote an image renderer for 3D meshes in Rust that renders thumbnails of customer-uploaded CAD files.- Used React and BabylonJS to construct an interactive 3D real time renderer for CAD files in the browser.- Rebuilt signup flow for customer-facing web application in Elixir to reduce friction towards acquiring new users.- Implemented the ability to import CSVs containing manufacturing quotes from third-party suppliers.- Organized a back-end guild for engineers to share knowledge and best practices and to grow professionally. - Provided on-call support to internal users of our quote and factory management software.

- Worked concurrently on multiple projects for different state governments, and interfaced with business and technical analysts to understand client requirements.- Developed an ETL tool in C# that reads data from an Oracle database, transforms the data so that it fits a new database design, and writes it to a SQL Server database.- Used F# and SQL to identify potential duplicate addresses in a SQL Server database.
