Harsh Kathiriya  • Peerlist

Taught an AI to master Flappy Bird using deep reinforcement learning in PyTorch. I went beyond a basic implementation to explore advanced techniques for more effective learning. • Core Algorithm: Deep Q-Network (DQN) with Experience Replay. • Advanced Enhancements: Implemented both Double DQN (to reduce value overestimation) and a Dueling DQN architecture (to improve state evaluation). • System Design: Engineered a modular agent with a YAML file for easy hyperparameter tuning and experimentation. • Tech Stack: Python, PyTorch, flappy_bird_gymnasium

Flappy Bird DQN - AI Agent

Spaced-repetition vocabulary app using the SM-2 algorithm, AI flashcard generation, and Anki deck import. A cleaner, more polished alternative to Anki for language learners.

Fluently

In-browser, AI-native Lottie animation editor with real-time multiplayer. Every action runs through one command pipeline, so an AI agent can call around 70 tools to operate the whole editor by chat. The most ambitious app I have built on the SDK.

Lotion

A bundle of Jackbox-style party games that friends join with a single room code. Built on real-time game rooms with server-authoritative scoring.

Party Pack

Real-time multiplayer quiz game in the style of Kahoot. Players join a live quiz from their phones with a room code, and scores update instantly. Questions can be AI-generated from any topic.

PopQuiz

LaTeX-powered resume builder with AI customization. Tailor your resume to any job description in one click, choose from multiple templates, and export clean PDFs.

Resume Builder

Live polling app, an open-source take on Slido and Strawpoll. Ask a question, share a link, and watch results come in live across multiple question types.

Tally

AI-native real-time collaborative LaTeX editor with Yjs CRDT sync, a Tiptap editor surface, and live PDF preview. Runs on the same TeX Live container infrastructure I built at DeepSpace. Think Overleaf, but with AI baked in.

TexPal

Turns a two-character dialogue into a captioned vertical video reel with text-to-speech voices, character portraits, and animated captions. I used it to make Peter and Stewie voiceover reels and grew an Instagram account to nearly 1,000 followers.
