Dhruv C.

I build production-grade software — clean backends, modern frontends, and blockchain systems that are secure, scalable, and ready to ship. Most recently, I worked as a contract code reviewer for Anthropic, one of the world's leading AI companies, validating model-generated code across Python, C++, Rust, Ruby, and C for production AI training datasets. Before that, I've shipped across the full stack — from REST APIs and real-time WebSocket systems to DeFi protocols and on-chain programs. What I build: Backend & APIs — Scalable Node.js/Express services,.NET and C#, tRPC, authentication systems, database architecture (PostgreSQL, MongoDB, Redis), real-time systems with WebSockets, and Go-based backend services. Frontend — Modern Angular, React and Next.js applications with TanStack Query, Zustand, Redux, TailwindCSS, and ShadCN UI. Focus on performance, clean architecture, and maintainability. Blockchain & Web3 — Full-stack decentralized applications, DeFi protocols, ERC20/ERC721 systems, NFT platforms, upgradeable contract architectures, Merkle airdrops, and oracle integrations using Solidity and Foundry. Solana programs via Rust and Anchor. AI & Developer Tooling — LLM-integrated systems, agent infrastructure, and developer tooling. I've implemented core ML algorithms (e.g. BPE tokenizer from scratch in TypeScript) and reviewed AI-generated code at production quality standards.
