I help blockchain projects, startups, and validators deploy secure, high-performance node infrastructure — including validator nodes, RPC endpoints, and indexers — with reliability, monitoring, and long-term scalability. Whether you are launching a network, running a professional validator, or scaling your dApp backend, I deliver production-ready Web3 infrastructure built on DevOps best practices. Services Included: Validator Node Setup: Full node sync, token staking, custom commission setup, anti-slashing architecture, and uptime optimization. RPC Node Infrastructure: Full node and RPC endpoint deployment (public or private) featuring high availability and fast state sync. Blockchain Indexers: Custom indexer deployment (The Graph, Subgraphs) for filtering blockchain events, transactions, and dApp backends. DevOps & System Admin: Advanced configuration using cloud instances (AWS, Google Cloud, bare metal), Docker, systemd, automated backups, and Prometheus/Grafana monitoring alerts. Supported Blockchains: Ethereum & EVM networks, Solana, Cosmos SDK, Polkadot, Layer-2 chains, and custom testnets. Message me before ordering to confirm your project requirements and hardware needs.
