Core Competencies
Featured Projects
Video Platform
Built a fullstack cloud native video platform enabling users to upload, browse, and watch videos with secure authentication. Implemented token based access control with Firebase Auth. Developed a containerized processing service on Cloud Run triggered by Pub/Sub events for automated video transcoding.
Web Agent
Built an AI web agent that receives natural language tasks and autonomously navigates websites to complete them. Implemented DOM based navigation with LLM reasoning and perceptual hashing for UI tracking, reducing costs 90%. Developed multi agent architecture with persistent browser sessions.
HintAI
Built a realtime coding assistant with <50ms semantic search over 1,000+ embeddings using pgvector HNSW indexing. Chrome extension streams code via WebSocket; parses structure to detect patterns. Implemented RAG retrieval with vector + metadata search; Redis caching cut API costs 65%.
NBA Point Predictor
Consolidated 10 seasons (2015–2025) of NBA data into unified dataset; engineered statistical features for training. Trained Random Forest model predicting player points; achieved 85% accuracy on hold out set via hyperparameter tuning. Created Jupyter visualizations showing feature importance.
