Projects

TEKKAL

AI-Friendly Slide Authoring Tool

Local-first, AI-agent-driven slide platform. Visual editor backed by a JSON scene graph, where every drag-and-drop action maps to structured code.

• React 19 + TypeScript, Vite, Tailwind CSS v4, Zustand
• Monaco Editor for JSON editing, KaTeX for math, TikZ support (server-side & WASM)
• File System Access API for local project management without a backend

AsyncPair

Asynchronous pair programming for teammates split across time zones. A post-commit git hook captures development context — commits, diffs, and developer notes — at the moment of every commit. The web app turns each handoff into AI-generated scenarios that predict what your teammate will hit next, plus a contextual AI chat scoped to the full git history. Author a scenario, hand it off, and review AI-generated code changes in a side-by-side diff. The entire project was built inside IBM Bob, IBM's AI-native IDE — the premise of the hackathon.

• Built end-to-end in IBM Bob, IBM's AI-native IDE — the hackathon's core theme
• Next.js 14 (App Router) + TypeScript web app; CLI tool built with Commander, installed via npm
• `asyncpair init` installs a post-commit git hook that runs `asyncpair capture`, extracting commits, diffs and notes through simple-git
• Gemini generates handoff scenarios and powers a contextual AI chat scoped to the full git history
• Author → Handoff → Pairing workflow; review and approve AI-generated code changes in a side-by-side diff view

Flanner

Knot API track

A mirror on your delivery habits. Pulls six months of real DoorDash / Uber Eats orders via Knot API, decomposes each dish into ingredients with K2 Think V2, generates a weekly home-cooked plan respecting calendar and dietary constraints, and pushes the exact ingredients to a real Amazon Fresh cart in one tap.

• Next.js 15 + React 19 on Vercel; FastAPI on Cloud Run; MongoDB Atlas
• Knot API in production mode: TransactionLink for delivery history, AgenticShopping for real Amazon Fresh cart push (checkout intentionally stubbed)
• K2 Think V2 for weekly plan reasoning; Gemma 4 31B for photo recognition and check-in classification
• Photon spectrum-ts bridge for live iMessage orchestration during the demo

MotZip

Bilingual (EN/KO) restaurant discovery built around two ideas: voice-first filtering on a 3D map, and an AI phone agent that calls restaurants for you. Speak a query, the map sinks non-matching food into the ground; pick questions (reservations, vegetarian, wheelchair access...), click "Call N selected," and watch real Twilio calls return ✓/✗/? per question.

• Next.js 16 + React 19 + Tailwind 4 frontend; MapLibre GL + Three.js for the 3D scene
• FastAPI on Cloud Run; Google Places API (New) for restaurant data, dedup'd across 7 cuisine groups
• Voice search: Google Cloud STT → Gemini 2.0 Flash filter extraction → in-process filtering → Cloud TTS reply
• Batch calls: Twilio chained <Gather> per question, per-turn STT + Gemini parsing, streamed back as a checklist
• Graceful degradation: ElevenLabs Scribe/Turbo as STT/TTS fallback, keyword heuristics if Gemini JSON parse fails

BCI Neural Visualization System

Real-time neural activity visualization and BCI array placement guidance system. Processes live data from a 1024-channel micro-ECoG array (32×32 grid) to help neurosurgeons optimize BCI array placement during surgery.

• CNN-based denoising (ResNet U-Net with CBAM attention)
• Kalman filter and EMA-based position tracking
• Real-time heatmap smoothing with configurable web UI
• 500 Hz sampling, ~20–50 ms end-to-end latency

Trippo

Replaces the group chat for the duration of a trip. A single trip room captures plans, photos, and tickets live; chat messages drive plan updates in real time, EXIF + GPS clusters photos by place and minute, and one tap turns the trip into a 1, 3, or 5-minute vertical recap reel for TikTok / Reels / Shorts.

• TypeScript backend on @mindstudio-ai/agent for DB + AI primitives; React + Vite mobile-first frontend
• Chat is the planner: Claude Sonnet extracts plan updates from messages in real time, Haiku polishes captions
• Photo clustering by EXIF + GPS: same place and minute groups into split-screen, distinct stops become animated map pins
• One tap renders a vertical 9:16 recap reel via Creatomate for TikTok / Reels / Shorts

Zerve × ODSC AI Datathon

End-to-end MLOps pipeline as a 32-block, 42-edge parallel-converge DAG inside the Zerve canvas: schema/leakage validation → EDA + 15-stage funnel → a 5-candidate AutoML pool → drift detection → champion picked for serving → weekly retraining loop. A Next.js frontend renders the DAG and calls a deployed FastAPI for live inference, reading canvas variables in real time.

• 5-candidate model pool: calibrated XGBoost + RF + HGB soft-vote ensemble, PyTorch tab-MLP, sklearn GBM — isotonic calibration throughout
• PR-AUC 0.2645, ROC-AUC 0.812 on 3.5M rows / 17,541 users (1.84% upgrade rate, ~53:1 imbalance); top-5% precision ~9× lift
• Tree SHAP + segment-level diagnostics map top features to marketing actions
• Weekly drift watch (PSI 0.10/0.25 + KS) with append-only event store, label-stable retraining gates, would_promote_new_model flag
• Next.js 14 + ReactFlow frontend draws the canvas DAG and queries the deployed FastAPI for live PNGs and inference

Booky

Social reading platform that transforms solitary reading into a connected experience. Readers highlight passages, discuss with friends, make story-branching choices (Detroit: Become Human style), and explore an AI-generated solar system visualizing reading compatibility.

• Next.js 16, React 19, Three.js for 3D planet visualization
• FastAPI backend with Firebase Firestore and ChromaDB
• Google K2 Think V2 for AI content, Gemini 2.0 Flash for voice Q&A, Vertex AI Imagen for illustrations

SegRec

Segment-Level Video Recommendation Engine

A segment-level video recommendation engine. Paste a YouTube URL and SegRec downloads it with yt-dlp and indexes it through the Twelve Labs API, auto-generates a clickable chapter timeline, and — when you click a chapter — finds and ranks similar moments across every indexed video, jumping playback straight to them. Built for the Video Understanding AI Hackathon at Northeastern around Twelve Labs' video foundation models.

• FastAPI + Python 3.11 backend; Vite + React + TypeScript + Tailwind CSS frontend with react-player playback
• Twelve Labs API for video understanding — Marengo embeddings for segment similarity, Pegasus for chapter generation
• Paste a YouTube URL → yt-dlp downloads it → auto-generated, clickable chapter timeline
• Click a chapter to surface ranked similar segments across the whole library, jumping playback straight to each match

CoHabitAI

AI Manager for Roommate Living

An Ideathon concept for shared-living harmony. CoHabitAI proposes an AI manager that defuses the everyday friction of roommate life — chore turns, unpaid rent, clashing schedules — by distributing tasks fairly, syncing everyone's calendars, tracking shared supplies with auto-reorder alerts, and sending smart reminders so nothing slips. Presented as the team's pitch for the LikeLion US 2025 Ideathon.

• Concept: an AI agent that distributes chores, coordinates schedules, and mediates roommate disputes fairly
• Proposed features — calendar integration, a shared-supplies tracker with auto-reorder alerts, smart reminders, and a household onboarding flow
• Pitch site built with React + Vite

EchoBoard

Context-Aware Ad Virtual Camera

An AI-powered virtual camera for video calls. EchoBoard transcribes the live conversation with speech-to-text, uses an LLM to detect the current topic, and composites a matching advertisement or branded background behind the speaker with real-time face detection — so what's on screen always echoes what's being discussed. Built as a 2025 Dream AI Hackathon project.

• Python 3.11; pyvirtualcam streams the composited feed into Zoom as a virtual camera, set up through OBS Studio
• Live speech-to-text plus Google's Gemini detect the conversation topic in real time
• OpenCV face detection overlays a topic-matched advertisement or branded background behind the speaker
