Cover image for Steam Market Bot is an
Steam Market Bot is an automated trading platform for the CS2 skin marketplace. It scans thousands of Steam Community Market listings in real time, detects underpriced items, and surfaces profitable buy opportunities through a clean dashboard. The CS2 skin market moves on volume and speed. Manual traders miss opportunities because prices shift in seconds. This bot solves that by handling the scanning, monitoring, and decision logic continuously. Features: Real-time market scanning across thousands of listings Live dashboard with balance, active orders, scan cycles, and bot status Configurable item filters (float ranges, sticker conditions, price thresholds) Warm-up mode to safely initialize bot sessions without triggering rate limits Live activity log so users can audit every action the bot takes Built with FastAPI, React, TypeScript, Python, Selenium, and the Steam Community Market API. Deployed with a PostgreSQL backend for trade history and analytics. This was a personal project that turned into a real tool. I built it to handle my own CS2 trading and shipped a polished version for others to use.

Cover image for MixerAI is a Chrome extension
MixerAI is a Chrome extension that consolidates ChatGPT, Claude, Gemini, and Perplexity into a single dashboard. Most heavy AI users are paying for 2-4 subscriptions and constantly switching tabs to use the right model for the right task. MixerAI fixes that. Features: Unified connection status for all major AI services in one panel Smart subscription tracking so you can see which plans you're on across providers Plan recommendation engine that suggests Free vs Pro vs Max tiers based on your usage patterns Single task input that routes your prompt to the best-suited AI for the job Built with TypeScript, React, Chrome Extensions API, Tailwind, and integrations with OpenAI, Anthropic, Google, and Perplexity APIs. This project came from frustration with my own AI tool sprawl: four tabs open, two paid subscriptions I wasn't fully using, and no system for deciding which model to ask. MixerAI is the tool I built to solve that for myself, and now I'm shipping it for others.

Cover image for Made this product video without
Made this product video without touching an editor. I recorded 30 seconds of myself talking, and a set of Claude Code skills built the rest: real product UI animated in code, the demo timed to my words, me in the corner on a studio backdrop, and music on the beat. Reply if you want to try it.
