Hi, I'm Yarin Solomon

Personal job screening agent that monitors WhatsApp groups and Telegram channels for job postings using Claude Haiku via the Anthropic SDK with Pydantic-enforced structured outputs. Built on a LangGraph StateGraph with adaptive mode selection — groups automatically switch from two-call (classify → extract) to a single combined call once they exceed a 70% job-post rate. Delivers instant Telegram alerts with one-tap Block Role / Block City buttons, a daily digest, semantic similarity search via ChromaDB, and a natural-language /ask command. Includes a public Telegram bot for live querying — available when the agent is running.

Full Backgammon engine with five AI opponents of increasing sophistication: random, heuristic (six-feature weighted evaluation), depth-limited minimax, MCTS with UCB1, and a PyTorch neural network trained to outperform the heuristic (~60% win rate). Includes a tournament mode that runs any combination of bots round-robin, with per-bot parameter tuning via a setup UI — no code changes required.

Upload an audio recording and receive a full transcript, structured summary, participant list, decisions, and action items. Uses OpenAI Whisper for transcription via a provider-swappable interface and Claude (claude-sonnet-4-6) for structured summarization over SSE. Handles files over 24 MB by computing an optimal FFmpeg bitrate from duration to compress audio just under the API limit before upload. Exports results as a formatted .docx file with RTL support for Hebrew.

Full-stack playlist manager for Spotify, SoundCloud, and Tidal. Features composable shuffle algorithms (artist spread, genre spread, chronological mix), automated reshuffles via a background cron job, and tools to merge, split, and deduplicate playlists. Enriches every track with audio features and genre tags via the ReccoBeats and Last.fm APIs.

A BGU university security assignment replicating Facebook's login and registration UI. Demonstrates credential harvesting techniques, SQL injection prevention via parameterised queries, and HTTP security headers (helmet.js) — built to explore the gap between a convincing phishing interface and secure backend practices.
