What I'm looking for

I'm looking to build production full-stack, Web3, and AI/LLM applications end-to-end, including backend APIs, integrations, smart contracts, and AI-powered solutions.

I've built production web, Web3, and AI/LLM applications at Web3Citadel, including multi-tenant SaaS products with authentication, subscriptions, scheduling, analytics, and Stripe/Razorpay payments. I also designed smart contracts and blockchain applications across EVM chains and Solana for trading, launchpads, NFTs, tokens, staking, swaps, and DeFi.

As an independent developer, I build end-to-end full-stack, Web3, and AI/LLM solutions. My work includes ForgePlace, a unified NFT, token, swap, staking, and launchpad platform, plus a legal-document RAG application for natural-language Q&A over PDFs.
