Card Game Crafter – Full Stack Dashboard & Card Management Platform
Designed and developed a modern full-stack web application for a custom card game platform. The application allows users to create, manage, and organize game cards through an intuitive dashboard with a responsive user interface and seamless user experience.
Nice work. The real strength of a dashboard like this is how quickly users can organize and find their cards, reducing management time is just as important as adding features.
Just shipped: a trilingual AI dealership platform for a used-car dealer in Spain.
One connected system, built and run end to end:
A site in Spanish, Romanian, and English. Their customer base is mixed, and no local competitor serves the Romanian community in their own language.
Carmen, a voice and text AI assistant that answers questions and captures leads 24/7, then emails and Telegrams the owners the second someone is interested.
A self-serve inventory panel: the owners add, edit, or sell cars themselves, and the site and the AI update in seconds, no developer in the loop.
Local SEO built to be cited by both Google and AI answer engines.
The owner works the service bay himself and had no time to run a website. So I built one that runs itself.

I built OmniBot AI, a full-stack dashboard designed to simulate and test automated WhatsApp Business workflows powered by AI. It bridges the gap between raw data storage and real-time LLM grounding.
Key implementation details:
• Knowledge Base Engine: Implemented a system context pipeline that allows users to write dynamic business rules/FAQs and sync them directly into vector context for the bot.
• Bilingual AI Support: Integrated Gemini AI with explicit prompt routing to automatically detect, process, and reply in both English and Arabic.
• Live MongoDB History Stream: Built a real-time JSON log viewer on the frontend that streams database updates, tracking session language, token usage, and cache success states.
• Infrastructure Analytics: Developed a monitoring component to track total synchronization logs and calculate average API response latency (optimized down to 1.2s).
Tech Stack: MongoDB, Express.js, React, Node.js, and Google Gemini API.
