Senior Rust Engineer

Delivered a Substrate-based mainnet blockchain for the Liquidity platform. Designed and shipped asynchronous Rust microservices using Tokio to handle high-frequency concurrent transaction flows across distributed financial infrastructure.

Built a multi-signature wallet system with secure distributed signing workflows for multi-party transaction authorization. Developed multi-chain indexing and streaming pipelines, real-time query handling, and high-frequency REST APIs for a digital credit system.

Managed production deployments on AWS EC2 using Docker, Prometheus, and Grafana for containerization and observability.

Architected and maintained Substrate-based distributed blockchain clients in Rust across 5–10 node testnet and mainnet environments, including 5ireChain. Built transaction validation and mempool systems processing 100–500 TPS with UTXO state management under concurrent load.

Implemented libp2p networking layers with gossipsub propagation, node synchronization, and request-response protocols across multi-node clusters. Designed low-latency gRPC communication layers using Tonic and Prost for inter-service coordination.

Integrated RocksDB and LMDB for persistent state storage, created cross-chain balance synchronization and MPC-based validation services, and delivered high-throughput blockchain explorer indexing pipelines. Built CI/CD pipelines and automated multi-node integration testing using GitHub Actions and Jenkins.

Built and maintained Ruby on Rails services and REST APIs before transitioning into Rust-focused blockchain infrastructure development.

Delivered centralized cryptocurrency exchanges using Ruby on Rails and the Peatio framework, with PostgreSQL-backed application services and API integrations.

Rebuilt backend services for a healthcare platform supporting more than 10,000 concurrent users and approximately 99.9% production uptime.

Reduced API response times by 40% through backend redesign and service-level optimization. Worked across Ruby on Rails, React, MongoDB, and TypeScript.

Built backend APIs and scalable web applications for healthcare and enterprise domains.

Delivered analytics dashboards and real-time APIs using Angular frontends and Ruby on Rails backends, with MySQL data storage.

Delivered production Rust API endpoints for an Ethereum DeFi yield and liquid staking protocol.

Built asynchronous REST services integrated with smart contract interfaces, achieving sub-100 ms response times under concurrent load.

Delivered a production Hyperledger blockchain and a public block explorer deployed on mainnet.

Implemented the transaction indexing pipeline and real-time query APIs supporting live blockchain data exploration.
