Driverless Kart

Building a practical outdoor testbed for autonomous driving algorithms

Converted a competition kart into a modular autonomous vehicle platform using ROS, computer vision, and custom control systems. Created the first outdoor testbed for researchers to validate self-driving algorithms in real-world conditions.

Tech: ROS, Computer Vision, Autonomous Control Systems

Cyberwheel

Designing an open-source electric unicycle that prioritizes safety and repairability

Developing an EUC that "never cuts power" - addressing critical safety concerns in commercial products. Features sealed electronics, crash-resistant design, and open-source hardware/firmware for a repairable alternative to proprietary systems.

Tech: Embedded Systems, Mechanical Design, Battery Management, Motor Control

Systematic Investment Analysis Framework

Building an AI-powered, systematic approach to stock analysis and valuation

Created a configuration-driven investment framework that eliminates bias through consistent methodology. Features an LSTM/Transformer neural network with 78.64% accuracy, analyzing 500+ S&P 500 stocks with multiple valuation models (DCF, RIM) and a static HTML dashboard.

Tech: Python, Machine Learning (LSTM/Transformer), SQLite, Pandas, Financial Modeling

Partle - Local Product Discovery

Community-driven platform for finding products in local stores

Full-stack web application solving the frustration of searching multiple stores for specific items. Features passkey authentication, interactive mapping, Elasticsearch-powered search, and community reliability ratings. Helps users find products instantly while supporting local businesses.

Tech: React/TypeScript, FastAPI, PostgreSQL, Elasticsearch, Leaflet, Passkeys (FIDO2)
