Here is a summary of some of my wins, projects, and achievements for the year 2025:

🛠️ Coding & “Vibe Coding” Projects

Check my public repositories at github.com/jooray

My (public) Projects

  • Worcoder Ecosystem: Developed the full stack for word-based encoding (human-friendly data representation), including the main library, worcoder-js, theworcoder-pwa, and theworcoder-desktop. Just a fun thing - you are not supposed to transfer data, only human voice over some frequencies. So let’s turn data into human voice and read the words!
  • AI & Data Tools:

    • venice-image: Created a Python tool for batch and interactive image generation using the Venice.ai API.

    • datasetgen-ng: Built an AI training dataset generator featuring parallel processing, approval workflows, and RAG support.

    • rag-backend: Developed a Retrieval Augmented Generation backend with FAISS vector storage and conversation history.

    • video-summarizer: Created a tool for intelligent video content summarization using chunk-based processing.

    • signal-summarizer: Built a tool to summarize Signal conversations from desktop exports.

    • rss2podcast: Released a tool to convert RSS feeds into podcast audio format using text-to-speech.

    • markdown2audio: Developed a converter for markdown documents to audio with PyTorch compatibility fixes.

    • reformatter-translator: Created an AI utility for reformatting and translating OCR’d books.

  • Payment & Voting:
    • Anypay.today: Built a web app allowing users to pay (almost) any crypto QR code using a Lightning wallet via Trocador swaps. PWA.
    • d21poll: Implemented the D21 voting method as an in-chat WEBXDC app to show how easy it is to develop. WEBXDC is a standard for apps that live inside a messaging group.
    • funding-rate-tools: Updated my crypto perpetual futures funding rate tracker to support multiple exchanges. I use it to monitor hedged staking positions (to hedge shitcoin risk)
  • Home Automation:
    • ha-simplex: Integrated Home Assistant with SimpleX Chat messenger.
    • simplex-ws-docker: Dockerized the SimpleX WebSocket server.
    • PulseLibre: open-source Pulsetto app
  • Nostr:
    • nostr-scripts & nostr-contact-form: Created utility scripts for protocol operations and a decentralized contact form.
