About Me

People first,
code second.

My experience has been based on listening and understanding the needs, actively talking to people to create meaningful solutions. I am at my best when listening to high level ideas, engaging with them to extract insights, and translating them into tech.

At Duke, I could engage with Computer Science through a human-centric lens. With an arts and sciences education, I gave myself time to explore the technical and social implications of technology. I want to create technology that serves a purpose and scales as a difference to someone's daily life.

My internships at BTG Pactual and Duke Code+ reinforced this. Whether shaping the auth of the bank for small and medium businesses, or collaborating with the Facilities Department of my University, I found purpose in the work I did through stakeholder vision and technical execution.

Things I've Built

🏋️

RepSense AI

Rep counters don't say much to users. So I built an ESP32 workout coach that calls the OpenAI API in real time, returning streams of bench press exercise sensor data for on-device feedback (rep count, imbalance, tempo, rest quality), emphasizing UX, reliability, and human-readable insights on the device display.

MealPilot (Microsoft AI for Good Hackathon)

Built a Copilot Studio extension using Azure Maps Search/Routing to return geo-personalized healthy-meal options across NYC; pilot with 28 students achieved 80% task success in 45s vs 5 min (85% faster), targeting areas with >30% food insecurity.

Mini Amazon - Database Systems

Full-stack e-commerce platform built for Database Systems. I owned the seller side: inventory CRUD, order fulfillment flow, and stock management; plus the UI/UX design across the app. Five-person team, Flask backend, PostgreSQL with complex queries, and a storefront that handled search, carts, and checkout end to end.

CNN Waste Classification

Deep learning model for automated waste classification using Convolutional Neural Networks. Trained on diverse waste imagery to accurately categorize recyclables, organics, and landfill items, promoting sustainable waste management practices.

This Portfolio

The site you're on right now! A portfolio I made with things I love in the sites I visit on the internet, such as the grain background, animations, and glassmorphism UI. Version-controlled with a main/prod branch strategy and semantic versioning (v0.x.x), deployed via CI/CD to Cloudflare Pages.

How it was like to intern at BTG Pactual Bank

Pactual. BTG. Better Than G... You name it. The people I worked gave all the names possible to BTG - they were fun, smart, and always ready to help. That made all the difference!

Lessons from My First Internship, the Code+ Program at Duke

Campus Space and Management! That was the name of our super-very-nice-to-work-with group! Really. I could learn more than I expected from our coexistence that summer.
