Oct 2024 - May 2026Co-led the university competitive programming club. Mentored students and led problem-solving workshops, and built and shipped the club's website, including the app that ran its raffle.
Stilo
Mobile app that builds outfits from your own clothes using AI. Includes a colorimetry module that finds your most flattering palettes, a RAG pipeline that turns plain-language prompts into coordinated outfits, and an interactive canvas for drag-and-drop editing.
Contributions
- Designed the recommendation pipeline that interprets prompts, finds matching clothes, and assembles outfits.
- Built the multiplatform app with a custom drag-and-drop outfit canvas.
- Provisioned cloud infrastructure on Azure using Terraform.
Technologies
Search engine for NASA's space biology research. Ask questions in plain English and get answers with citations to real NASA publications.
Contributions
- Built the backend — chat, history, users, and RAG orchestration with Vertex AI.
- Developed frontend features: interactive knowledge graph, article favorites, and chat integration.
Technologies
IoT water monitor for regions where the supply is unreliable. An Arduino reads the tank level every minute, the dashboard shows it live, and email alerts fire before you run dry. It has been running on my family's tank for over a year.
Contributions
- Designed the full system — Arduino firmware, a Go Lambda for sensor ingestion, the NestJS API, and the React dashboard.
- Trained an LSTM to forecast when the tank would empty, measured it against the latency it added, and switched it off.

Havi
Proactive banking copilot built in two days for the Hey Banco datathon. I built the mobile client: 8 screens, a shared component library, and a typed context layer that falls back to mock data when the backend is down.
I discovered my passion for programming at 16 through Arduino projects, which sparked my interest in software development. This early experience taught me the importance of problem-solving and creative thinking in technology.
When I'm not coding, I enjoy gaming, spending time with friends and family, reading, and playing guitar. I'm always eager to learn and chat about new tech.
