about this service
I design and build high-performance crypto applications that operate reliably at scale. With deep expertise in blockchain infrastructure and data systems, I create robust platforms that interact directly with on-chain data across networks such as Ethereum, Solana, Aptos, Starknet, Sui and Cosmos. From real-time indexers and analytics engines to staking trackers and custom blockchain APIs, I develop systems that process large volumes of data with low latency and high accuracy. My experience includes building multi-chain indexers, event-driven architectures using Kafka, and high-throughput backends powered by FastAPI, Rust, and Python. I focus on creating production-ready solutions—secure, scalable, and optimized for performance. Whether it's designing a blockchain explorer, a DeFi analytics platform, or a custom data pipeline, I ensure clean architecture, efficient data modeling (PostgreSQL), and reliable ingestion from RPC nodes and on-chain events.
