They need AI systems that solve real business problems, automate operations, and generate measurable ROI.
Over the last 15+ years, I've worked as a Senior Solution Architect and CTO, helping start-ups and enterprises design and build scalable software products. My expertise started with Blockchain/Web3 architecture, where I delivered secure, enterprise-grade decentralized applications and digital asset platforms.
As Generative AI transformed the industry, I expanded my focus toward building production-ready AI solutions that integrate seamlessly with existing business processes.

If you're building DeFi infrastructure, a Solana protocol, or a high-performance blockchain system โ and you need it done right the first time โ 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:
โ Substrate-based L1 blockchain nodes with custom consensus and p2p networking
โ MPC-based distributed signing and MultiSig wallet infrastructure
โ Cross-chain indexers processing high-throughput block and transaction streams
โ Solana programs, RPC integrations, and on-chain analytics pipelines
โ gRPC microservices, async Tokio APIs, and RocksDB storage layers
โ 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 โ 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.
