πŸ‘‹ Hey there! I'm LSZ

Welcome to my GitHub profile! I'm a full-stack developer, creative coder, and digital tinkerer with a deep appreciation for open-source, expressive interfaces, and all things experimental. Here's a bit about my tech journey πŸ‘‡


πŸš€ About Me

  • 🧠 Started out with Discord.js bots back in early 2018 β€” music bots, chatbots, and moderation tools.
  • 🌐 Played around with hosting platforms like Heroku, Glitch, Replit, and learned the ropes of cloud deployment and sandbox environments.
  • πŸ€– Dabbled in early chatbot AI using Brainshop, sparking an interest in neural networks.
  • πŸ›’ Built personal websites and academic projects β€” including a flower bouquet marketplace (no real flowers, just virtual charm πŸ’).
  • 🧬 During the 2021-2022 NFT & crypto wave:
    • Deployed custom smart contracts on Polygon (Matic) and testnets.
    • Used IPFS for decentralized file storage.
    • Minted and sold NFTs on Opensea, Foundation, and WazirX (~$100 in NFT sales).
  • 🎨 I'm also a digital artist (real art, no AI slop).

πŸ’Ό Work Experience (Tech-Focused)

  • πŸ”§ Migrated legacy apps from Struts to Spring Boot, and tested multiple application instances.
  • 🧩 Worked on JBPM-based Spring Boot backend modules, including building backend flows, demos, and collaborative presentations.
  • 🐳 In a new project, explored:
    • Docker for containerized development.
    • Hyperledger & CredoJS for blockchain-based credential systems.
    • PostgreSQL, Express.js, Sequelize ORM, and TypeScript backend stacks.
    • Android Studio, building wallet apps based on Bifold to test with agents.

πŸ§ͺ Latest Interests

  • πŸ”Š Exploring Automatic Speech Recognition (ASR):
    • Tools: Whisper, Vosk, Kaldi.
    • Working on domain adaptation under tight computational constraints.
    • Gaining deep familiarity with speech tech pipelines and acoustic models.
  • 🎨 UI Experiments: Rebuilding the Twitter UI using React + plain CSS.
  • 🌐 Revamped personal site, now live at: lsz.varnexo.in with custom subdomains, deployed on Vercel.
