Selected Projects
Event Copilot AI Platform (v1–v3)
Featured at IMC2025, AIImpact 2026, and IEW2026 | Tech: NestJS, Next.js, Gemini, OpenAI, PostgreSQL, Streaming RAG | 2025-2026
- Built a Copilot AI platform across three major versions on a NestJS monorepo, using Gemini and OpenAI for event search, conversational assistance, and grounded AI responses across CMS and attendee workflows.
- Added a Next.js frontend for attendee-facing Copilot experiences, supporting natural-language event interactions, smart recommendations, and UI flows for AI-driven assistance.
- Integrated profile matching for personalized recommendations, enhancing user relevance and experience.
- Designed the backend around reusable libraries for auth, database, Redis, sockets, S3, notifications, and configs, enabling a scalable architecture across administrative and user-facing services.
- Used streaming RAG protocols and prompt-engineering layers to keep responses grounded in event data and suitable for real-time interaction.
Event Database AI Agent
Tech: AWS Lambda, API Gateway, JWT, Claude Bedrock, PostgreSQL, MySQL | 2025-2026
- Implemented a secure, serverless Event Database AI Agent using AWS Lambda, API Gateway, and JWT-authenticated requests that translate natural-language questions into safe SQL over PostgreSQL/MySQL event databases.
- Designed a modular agent runtime with dedicated database tools and a Schema Workflow Manager, backed by a workflow metadata PostgreSQL DB storing frozen schemas, prompt registry, query audit logs, and conversation history.
- Added strong guardrails and observability: read-only source DB access, automatic LIMIT injection, destructive-SQL blocking, Chart.js-ready outputs, and structured logging for workflow/tool behavior.
- Built a Dreamcast analytics harness that runs scripted question batches against live event data, compares environments, and produces QA reports on attendance, multi-day visitors, peaks, and schema drift.
Agent Website Creator
Tech: Next.js, FastAPI, LangGraph, OpenAI, Gemini, DeepSeek, MCP | 2025-2026
- Designed an AI-powered website creator with a Next.js 16 frontend and FastAPI/LangGraph backend that analyzes prompts or uploaded documents and generates working sites through a multi-step pipeline.
- Built a two-step generation flow: analyze a prompt/doc into a draft PRD, then generate the site by skipping redundant reasoning when the PRD is already filled, saving time and improving reliability.
- Added pluggable model routing across OpenAI, Gemini, and DeepSeek, letting the system choose the right provider for thinking, planning, content generation, and engine selection.
- Integrated MCP-based tools like Silex, Stitch, and Playwright, along with document extraction and canonical data processing, to convert PDFs and prompts into production-ready site outputs.
AI Photobooth Identity System
Tech: Buffalo_L (Backend)
Developed photobooth software that utilizes the Buffalo_L framework for the backend side to handle the embedded machine learning model for real-time facial scanning, enabling accurate identification and grouping of photos belonging to the same individual.
