I'm a passionate Web3 FullStack Developer and AI Enthusiast specializing in Solidity, Solana, Next.js, LangChain, and blockchain integrations. With over 7 years of experience in software development and a strong background in decentralized applications (dApps) and LLM-based tools, I build secure, scalable, and intelligent digital solutions.
🔹 Expertise in:
- 🛠 Smart Contracts (Solidity, OpenZeppelin, ERC20, ERC721, ERC4626, Vaults)
- 🛠 Programs (Solana, Anchor, Rust, SPL)
- ⚡ Web3 Frontend Development (Next.js, React.js, TypeScript, UI/UX)
- 🔗 Blockchain Interactions (Ethers.js, Web3.js, DeFi protocols, CLMMs)
- 🤖 AI & LLM Tools (LangChain, LangFlow, RAG, OpenAI, Claude, Vector Stores, AI Search Agents)
- 🔐 Security & Optimization (Gas efficiency, smart contract audits)
- 🏗 Backend & DevOps (Node.js, NestJS, databases, cloud deployment)
Decentralized Vault System: Implemented ERC4626 vaults for native BERA tokens, ensuring seamless staking and yield optimization.
Revolutionary Payment Wallet: Build on Solana, RUST, Anchor
Blockchain Betting dApp: Designed a smart contract that enables users to place bets on cryptocurrency performance.
NFT Smart Contracts: Developed and deployed custom ERC721 contracts, integrating with frontend for seamless user experience.
Exploring Berachain DeFi: Research and implementation of Concentrated Liquidity Market Makers (CLMMs) for yield optimization.
Retrieval-Augmented Generation: Built an intelligent RAG-based AI system combining LLMs with custom document knowledge bases using LangChain and Vector Stores.
AI-Powered Search Agent: Developed a LangChain-based agent for multi-step reasoning and smart querying over custom data sources.
