Hi, I’m Yan.

Yanbao Li Yan

Open to software engineering and applied AI roles

Information Systems student at Stony Brook University. I build local-first desktop apps and explainable AI services, and I’ve shipped Windows and Android previews, public web demos and data-driven modeling work.

Selected projects

Software I’ve designed, built and released.

C# desktop media workflow

VideoHarvester

Released · Windows

A local-first Windows app for authorized YouTube and Bilibili downloads.

Orchestrates yt-dlp and FFmpeg asynchronously, with preflight checks for quality, size, disk space and destination.
Playlist-aware queues, platform-ID deduplication, persisted history and recovery of unfinished tasks.

Explainable video-ad decisions

AdMind

Public demo · Web / API

A public three-scenario demo and Fastify API that decides where long-form video ads can go, and explains why.

Normalizes Zod-validated TwelveLabs evidence and combines it with player and campaign constraints in a typed, deterministic policy engine.
Browser-side MediaPipe scores four pause-ad positions and returns auditable reasons, including when no safe area exists.

Cross-platform local-first media

Sona

Preview · Windows & Android

A local-first Flutter / Dart music and music-video player, released as Windows and Android previews.

One SQLite core for the offline library, playlists, queue and history, with SHA-256 content deduplication.
Layered metadata matching with MusicBrainz and an optional Chromaprint / AcoustID fallback, plus optional Supabase sync.

Research & modeling

Competition and lab work in optimization and machine learning.

Lead programmer · Optimization2025

CUMCM · Drone optimization

Owned programming and optimization modeling for coordinated drone deployment: built the geometric model, then tuned simulated annealing, Bayesian optimization, genetic algorithms, island models and NSGA-II for multi-objective strategies.

About & education

I’m Yanbao Li, and I also go by Yan. I care about clear system design and features that stay useful after the demo.

I study Information Systems at Stony Brook University, after transferring from Anhui University where I studied Digital Media Technology.

My recent work spans C# media workflows, Flutter / Dart local-first apps, TypeScript / Fastify services, and multimodal model experiments involving data preparation, tuning and evaluation.
