  As a camp counselor, my main job is to look after the students and make sure they’re safe. I also help out with organizing different events and ensuring that the students get to their classes on time. As part of my role, I assist the instructors as a teacher assistant whenever they need it.

  I was also given the opportunity to be a substitute teacher for an introductory coding class and an algebra class. When I filled in, I taught the coding class the basics using Scratch, and for the algebra class, I covered formulas and concepts using Desmos.

  As Webmaster, I architect and maintain IEEE UCSD’s technical infrastructure, spanning dashboards, authentication systems, internal tooling, and self-hosted production services.

  I built the IEEE Dashboard using Convex as the backend and TanStack Start as the frontend, creating a centralized platform for event discovery, reimbursement submissions, event management, sponsorship tracking, resume database access, link sharing, user management, and analytics. I integrated Google APIs, including Google Calendar synchronization, to ensure real-time event updates and improved member engagement across the organization.

  I led the initiative to self-host IEEE’s core infrastructure by deploying our dashboard, main website, authentication services, and internal tools on a VPS environment. Using open-source tooling such as Dokploy, I manage containerized services including databases, authentication providers, and internal microservices. This increased reliability, security, and operational control while reducing reliance on external platforms.

  I implemented organization-wide authentication using Logto with OpenID Connect and JWT-based security, establishing role-based access control across all IEEE services. This unified authentication layer secures internal dashboards, project tools, and administrative systems under a standardized identity infrastructure.

  Beyond web systems, I developed the IEEE Presence Tracker using Convex as the backend and a Raspberry Pi with AstroJS as the frontend. The system leverages Rust-based Bluetooth proximity detection to automatically determine member attendance in real time. I also built the IEEE Parts Platform, featuring a 2D blueprint interface for inventory visualization and a structured check-in and check-out system powered by Convex and TanStack Start.

  As Visionarieees Coordinator, I helped oversee the strategic planning and execution of IEEE UCSD’s Visionarieees competition, a student-focused innovation and design challenge.

  I contributed to high-level decision-making for the competition, ensuring alignment between project goals, technical feasibility, and organizational priorities. I reviewed proposed material lists and budgets to ensure the event remained financially sustainable while still providing participants with the necessary resources to build competitive projects.

  I served as a liaison between faculty advisors, sponsors, and IEEE leadership, maintaining clear communication and ensuring expectations, deliverables, and timelines were aligned. I also supported logistical planning, including materials coordination, operational setup, and event-day execution to ensure a smooth experience for participants.

  Through cross-functional coordination and financial oversight, I helped deliver a well-structured and professionally executed engineering competition.

  As Vice Chair Finance, I oversee the financial strategy, compliance, and operational integrity of IEEE UC San Diego’s multi-program engineering organization, supporting competitive teams, large-scale events, and quarterly project initiatives.

  I work directly with corporate partners to ensure grants and sponsorship funds are properly allocated and distributed. I took the initiative to streamline financial operations by collaborating with platforms such as Zeffy and Privacy.com, modernizing our payment processing workflows, and improving transparency across transactions.

  I draft and manage Statements of Work (SOWs) with sponsors and partners, ensuring clear deliverables, funding terms, and accountability standards. I established structured auditing practices internally to ensure proper logging, categorization, and review of all purchases, thereby enhancing financial oversight and ensuring long-term sustainability.

  I manage all reimbursements for officers and members, ensuring timely processing while maintaining strict documentation standards. I also attend Executive Committee (ExComm) meetings to pitch funding strategy, advocate for resource allocation, and align financial planning with organizational growth.

  Through compliance oversight, structured financial controls, and corporate engagement, I ensure IEEE UCSD operates efficiently, transparently, and in full alignment with nonprofit regulations.

  As Vice Chair of Projects, I oversee IEEE UCSD’s flagship technical initiatives, supporting hundreds of engineering students across competitive robotics, high-performance computing, and hands-on design programs.

  I manage TritonBots (RoboCup SSL Division B), where I secured $10,000+ in funding to expand hardware resources, improve materials access, and fully fund competition travel. I also facilitated intercollegiate scrimmages with Georgia Tech to elevate competitive readiness and ensure the team remains nationally competitive.

  For Supercomputing, I provide technical and operational oversight to ensure milestone execution, resource alignment, and sustained progress toward national competition performance.

  I redesigned the structure of our Quarterly Projects (QP) program to improve participant retention and scalability. This included implementing formal Bill of Materials (BOM) requirements, streamlining parts allocation, and introducing stronger logistical planning to support growing participation.

  Additionally, I manage IEEE’s Project Space, ensuring it remains fully stocked, inventoried, and operational. I implemented improved inventory tracking systems and officer accountability processes, including structured logging for Open Access Hours to maintain consistent member support.

  Through strategic funding, operational systems, and infrastructure development, I focus on scaling IEEE’s technical programs while maintaining execution quality and long-term sustainability.

  As a Lab 3.0 Fellow at HDSI, I contribute to the lab’s technical infrastructure, student-facing platforms, and outreach initiatives supporting data science and engineering education.

  I developed the lab’s public-facing website using AstroJS, building a structured platform to showcase projects, events, and initiatives through Markdown-driven content. I implemented the table of contents, drafted the Privacy Policy, and ensured the site complied with COPPA standards. The platform includes dynamic member listings and is fully responsive across desktop and mobile devices.

  I also built a collaborative code-sharing and debugging platform using AstroJS and Convex to support partnerships between the lab and local high schools. The platform allows students to share and debug code online without requiring account creation. It supports versioning, structured log visualization, syntax highlighting, and diff comparison, providing an accessible and lightweight development environment for educational use.

  Building on an existing open-source inventory tracker, I am extending the system to support a graphical user interface and potential mobile integration to enable student clock-in and clock-out tracking. This improves operational visibility and simplifies administrative workflows.

  In addition to core development work, I provide technical guidance across lab projects, including UI design support, AI prompt engineering, and integration of tools such as OpenRouter. I occasionally participate in outreach efforts, assisting with school engagement activities and providing debugging support for the Robot Flower project.

  Through full-stack development, systems thinking, and educational outreach, I help scale Lab 3.0’s technical capabilities while supporting broader community engagement.
