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 👇

• 🧠 Started out with Discord.js bots back in early 2018 — 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.
• 🤖 Dabbled in early chatbot AI using Brainshop, sparking an interest in neural networks.
• 🛒 Built personal websites and academic projects — including a flower bouquet marketplace (no real flowers, just virtual charm 💐).
• 🧬 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.

• 🔧 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.

• 🔊 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.
