I develop distributed systems frameworks and solutions, game server software and solutions, and cross-platform middleware for game servers and clients. I also build runtime libraries and developer tools.
I work with C++, Rust, Go, Lua, JavaScript, TypeScript, and Java.
- Maintainer of @atframework and @xresloader
- Member of @open-telemetry, Approver for OpenTelemetry C++
- Based in Shanghai, China
- Writing notes, deep dives, and engineering case studies at owent.net
- Distributed systems & cloud-native infrastructure: server frameworks and deployment solutions, communication systems, gateway services, service discovery, topology-driven routing, and automatic reconnection
- Game server development & solutions: backend architectures, stateful object routing, write-ahead logging (WAL) based distributed transactions and message queues, and reusable components for rank board, chatting, friend, guild, matchmaking, teams, High-performance player-to-player (P2P) marketplaces(support search across multiple attributes and tags, exchange-style trading with dynamic pricing, and direct-trade modes for competitive order claiming, flash sales, and auctions), Unreal Engine Dedicated Servers supporting/optimization and etc.
- Cross-platform server/client middleware: communication libraries, RPC frameworks, protocol integration, client SDKs, shared gameplay components, and configuration/data loading pipelines
- Runtime & concurrency: coroutine libraries, task scheduling, channels, and low-overhead components
- Observability: OpenTelemetry integration, metrics/tracing pipelines, diagnostics, and performance tuning
- Build & engineering: CMake toolchains, CI/CD workflows, configuration/code generation, data export pipelines, and game server/client build, packaging, and deployment tooling
