Hi, I'm Maciej 👋
Software Engineer and Security Researcher focusing on AI, and Security. Happy reading! ðŸ¤
About
I'm passionate about building innovative AI solutions and finding security vulnerabilities. I've discovered 8 security vulnerabilities in Google Chrome, earned over $23,000 in rewards and ranked in Google's top-100 security researchers. I'm currently focused on developing JsonGPT, an AI-powered API that provides structured JSON outputs, and have also participated in Google AI hackathons.
Featured Projects
I build projects from 0 to 1, turning ideas into reality. Take a look at some of my favorite projects below.
JsonGPT
A simple API that helps developers generate structured JSON data from AI models like OpenAI, Gemini, Meta LLama and more. Features include JSON validation, caching, streaming, and a free playground to test prompts.
DarksAI: Mystery Stories Mobile Game
A mobile mystery game powered by Gemini AI for story generation and interactions, ElevenLabs for voice synthesis, and Runway AI for visuals. Players solve cases through voice or text chat by interacting with an AI Agent.
TableByAI - No-Code AI Tables
An AI-powered application that automatically extracts and organizes data from uploaded files (images, videos, audio) into structured table records. Built during Google AI Hackathon, it uses Gemini/Vertex API to analyze media and populate customizable tables that can sync with Google Sheets.
Loothunt
Loothunt was a player-to-player marketplace that enabled gamers worldwide to trade virtual goods and services across multiple online games. The platform successfully served over 10,000 users before being discontinued.
