Anuj K.

If you're building DeFi infrastructure, a Solana protocol, or a high-performance blockchain system — and you need it done right the first time — read on. I'm Anuj, a Rust blockchain engineer with 12+ years of engineering experience and 6+ years shipping production Rust systems that handle real transactions, real money, and real scale. Not side projects. Not tutorials. Production mainnet systems. Here's what I've actually built: — Substrate-based L1 blockchain nodes with custom consensus and p2p networking — MPC-based distributed signing and MultiSig wallet infrastructure — Cross-chain indexers processing high-throughput block and transaction streams — Solana programs, RPC integrations, and on-chain analytics pipelines — gRPC microservices, async Tokio APIs, and RocksDB storage layers — Full production deployments on AWS, Docker, Kubernetes with Prometheus monitoring Previously: 7 years at Antier Solutions building blockchain infrastructure. Contract work for Satschel Inc, Texas — a US FinTech company building distributed financial systems. My clients don't come back because I'm cheap. They come back because the systems I build don't break. If you have a serious blockchain or DeFi infrastructure challenge — let's talk.
