About Me
Engineer by training, builder by nature.
I graduated from Virginia Tech in December 2025 with a B.S. in Computer Science and a Mathematics minor, and I'm now pursuing a Master of Engineering in Computer Science and Applications, expected December 2026.
I have diverse experience across enterprise and startup environments — from mobile engineering at Capital One and enterprise-scale infrastructure automation at Collins Aerospace (RTX) to full-stack applications at Nora AI and Knowmadics. I'm passionate about building scalable solutions and have won two startup competitions at Virginia Tech.
Winner of the Virginia Tech Startup Sprint 2023 Grand Prize ($2,500) and the Virginia Tech Spring Entrepreneurship Challenge 2025 ($500 Grant).

Experience
Where I've worked
My journey in software engineering and business analysis across enterprise and startups.
Software Engineering Intern
Capital One ↗- Developed Android features in Kotlin and Jetpack Compose for an end-to-end physical card kiosk experience, integrating mobile workflows with backend APIs to deliver a production-style prototype within a 10-week Agile development cycle.
- Built customer-facing card issuance and replacement flows using reusable mobile components, contributing to an initiative projected to increase Day 0 card activation by 55%+ while helping reduce $11.7M/year in expedited shipping costs.
Engineering Application Development Intern
Collins Aerospace (RTX)
- Architected a MongoDB automation platform using Crossplane XRDs, Kubernetes, Helm charts, and Argo CD GitOps, developing end-to-end CI/CD pipelines that accelerated database provisioning by 80%.
- Deployed a Docker-based Borg backup service via Puppet, running daily multi-threaded MySQL dumps to Borg, cutting the backup window from 2.5 hours to 30 minutes and enabling rapid restores for critical databases.
- Executed the migration of enterprise-scale AWS infrastructure from a deprecated legacy environment to new cloud environments, establishing standardized migration patterns and documentation to streamline future application transitions.
Associate Business Analyst
Knowmadics ↗- Created detailed requirement documents for 2 flagship products by conducting weekly stakeholder interviews across international teams, resulting in reduced specification ambiguity and accelerated development cycles.
- Engineered internal automation tools that streamlined software version release processes, reducing deployment time by 25%.
Software Engineering & Product Management Intern
Knowmadics ↗- Developed automated REST API test suites for a personnel tracking system using Postman, achieving 99% functionality coverage across 50+ endpoints and reduced production bugs by 30% through C# and .NET backend enhancements.
- Created 20+ Angular.js components including dynamic data tables and interactive dashboards for improved user experience.
- Led end-to-end QA testing for web and mobile applications across 6 Agile sprints, creating structured test plans and managing bug lifecycles in Jira and Azure Boards to reduce average issue resolution time by 20%.
Software Engineering Intern
Nora AI ↗- Developed key backend features for an AI mock-interviewer platform using ASP.NET Core, including interview session management and response analysis endpoints, while creating comprehensive Swagger documentation for 20+ API endpoints.
- Converted Figma wireframes into 15+ reusable React components powering a platform used by 1000+ active users.
