Gateway FM provides blockchain infrastructure, RPC, validator, staking, and data-availability services. Company materials describe it as supporting dozens of chains and processing billions of RPC requests daily (raised ~$4.6M). Lead a team of 5 engineers building Go backend services and data infrastructure across multiple production projects. Design event-driven services for real-time data ingestion, transformation into execution signals, and integration with external systems. Own system design end to end: backend services, deployment, monitoring, and production support. Coordinate engineering delivery — task planning, technical specs, documentation, and code review. Selected Projects: 1. Universal Indexer Service — Designed and built a Go listener/indexer (any EVM network) using code generation. Standardized event handling and data extraction into reusable patterns, turning slow per-chain integration into a fast, repeatable process; deployed across Ethereum mainnet, Base, Arbitrum, and numerous rollups. 2. Price Oracle (Haust Network) — Built the Go backend pipeline processing external pricing inputs and delivering them to downstream consumers reliably: a pull oracle sustaining ~1,000 req/s at ~1s latency and a push oracle pushing price updates every 500 ms. Supported in production. 3. Data Provider (Flare Network, v1 & v2) — Designed backend services and submission logic for reliable, time-sensitive external data delivery in a financial context. 4. Azure Integration (Gateway Presto) — Reworked backend components to integrate the product with Microsoft Azure for cloud-based distribution.

Web3 development team delivering DeFi, payment, and infrastructure projects. Designed backend integration points and on-chain/off-chain coordination for production Web3 applications. Worked on financial application infrastructure (e.g. **Wirex Pay**) where reliability, security, and transaction correctness were central. Integrated backend services with on-chain components and frontend applications.

Developed backend microservices in Go using gRPC and REST for production systems. Designed APIs and service interfaces; contributed to backend architecture and integration planning. Built and maintained service-level documentation and technical specifications. Supported integration between backend services, databases, and external systems.
