Building AI-powered, blockchain and full stack products for clients across fintech, healthcare and logistics. - Design and ship production web applications using React, Node.js, TypeScript and ASP.NET Core MVC, backed by PostgreSQL and MongoDB. - Build cross-platform mobile apps in React Native for Android and iOS, including crypto wallet and P2P trading apps with KYC and escrow flows. - Develop smart contracts and Web3 integrations — Solidity on Ethereum, Rust and Anchor on Solana — covering tokens, DeFi mechanics and NFT systems. - Build AI agents and agentic pipelines with LangChain, CrewAI and AutoGen — systems that plan, call tools and act autonomously rather than just answering prompts. - Develop analytics dashboards and reporting layers, including screening and hospital management systems with complex aggregation and drill-down views. - Build automation pipelines that connect LLMs, APIs and third-party platforms into workflows that run without manual intervention. - Handle full delivery cycle: requirements, architecture, implementation, testing, deployment and handover documentation.

Developed smart contracts and Web3 applications across Ethereum and Solana. - Wrote and tested Solidity smart contracts for token systems, DeFi mechanics and NFT marketplaces. - Built Solana programs in Rust using the Anchor framework. - Integrated wallets, on-chain reads and transaction signing into React front ends. - Worked on contract security review — reentrancy, access control, arithmetic safety and upgrade patterns — before deployment. - Built the off-chain layer around contracts: indexing, APIs and admin tooling so non-technical users could operate the system.
