Work Experience

L2E (Learning to Earning) Corporate System Engineering Intern

Accenture (via eTeam) · Minneapolis, MN

Jun – Aug 2025
  • On a 5-person team, built SQL ETL scripts and stored procedures that decided which of 3,000+ Power BI users to migrate and what permission level (RBAC) each received on the new enterprise platform; all 3,000+ users moved on schedule, with every change passing supervisor code review.
  • Owned the ~50 admin accounts that needed department-specific access (Receivables, Payables, HR, Invoicing), migrating and verifying each one individually.

Software Engineering Intern

New Visions Foundation · Minneapolis, MN

May – Aug 2023
  • Wrote Python scripts that automated applicant screening, checking each application against the program's eligibility rules (county residency, age limit, program fit) and advancing qualified applicants to interviews; the review cycle dropped from over 3 weeks in 2022 to 9 days in 2023.
  • Built the applicant filters in the selection team's admin dashboard, matching the screening scripts' eligibility rules, and improved the dashboard's UX/UI for reviewing and advancing applicants, trading peer code reviews with the other software engineering interns.

PulseCheck

Deepfake detection with pulse signals

A tool that aims to identify deepfake videos by checking for a real pulse. A live face shows tiny skin-color changes with every heartbeat (remote photoplethysmography, rPPG), which manipulated faces may not reproduce consistently. PulseCheck measures that pulse in several face regions and checks whether they agree, and it says "inconclusive" instead of guessing when the signal is too weak.

Multilingual AI Front Desk Assistant

A voice-activated, multilingual front-desk assistant for the non-profit CLUES, in daily use since October 2025.

  • Designed and deployed a voice-activated, multilingual front-desk assistant on a Raspberry Pi, integrating the Gemini REST API with push-button activation; in daily use since October 2025, handling 50+ interactions per day.
  • Iterated on prompts to reach an 85% form-completion rate, measured from the kiosk's logs of completed forms.
  • Built the full hardware/software stack with a custom 3D-printed enclosure for ~$70 in parts, a fraction of the cost of commercial self-ordering kiosks.

School Management REST API

A cloud-hosted backend for managing a school's students, teachers, courses, and enrollments.

  • Built a Flask REST API backed by MySQL to manage student, teacher, course, and enrollment records.
  • Designed the relational schema and CRUD endpoints, writing the SQL to create, retrieve, update, and delete records.
  • Deployed to Railway, delivering a reliable cloud-hosted backend for real-time school data management.
