Free SAT + ACT prep game for iOS · no ads, no paywall

• Duolingo-style progression: a skill path, XP, streaks with freezes, weekly leagues, daily quests, chests and gems
• Elo-based mastery per skill drives adaptive question selection and a predicted score
• Server-authoritative game economy in Cloud Functions; Firestore rules block clients from writing progress
• Content pipeline: Claude-generated questions are blind-solved for verification, then human-reviewed before publishing

Built with Expo, React Native, TypeScript, Firebase (Auth, Firestore, Cloud Functions), EAS

• Background job syncs every user every 30 minutes with incremental fetching

Built with Firebase Auth, Firestore, Docker, Caddy

Hardware · field-tested on a tree farm

Designed and built a drone that holds two gallon drums and sprays liquid.

• Designed the power system end to end
• Built ground-station control in place of a conventional RC link
• Debugged failures by bisecting the stack
• Real-world testing on a tree farm
• Future use: window cleaning for office buildings

24/7 automated phone receptionist for businesses

• Handles inbound phone calls with conversational AI
• Designed to scale with SMS/email confirmations, Google Calendar scheduling and daily summaries

Built with n8n, Vapi

MIT 16.412J Cognitive Robotics

• Simulated autonomous drone agent that picks up packages, avoids obstacles and manages battery constraints
• Implemented the decision-making logic and environment interaction

Built with Python

Machine learning for time-series forecasting

• Enter a stock ticker and the model predicts price movement over the next 50 days
• Monte Carlo sampling for uncertainty quantification

Built with Python

A 60-day case study on strength, body composition and joint pain in an adolescent male

Designed and ran a 60-day controlled experiment comparing high-volume and low-volume training. Low-volume protocols achieved equal or better outcomes with reduced injury risk.

• Formulated the hypothesis and controlled for nutrition, sleep and exercise selection
• Collected daily quantitative data across multiple metrics
• Identified the limits of bioelectrical impedance measurement and applied statistical corrections
• Wrote a formal paper covering methodology, results, discussion and practical applications
