I build backends end-to-end — distributed systems, LLM gateways, middleware automation, and the infrastructure that keeps them reliable. Backend developer focused on microservices, cloud architecture, and open-source work in the AI tooling ecosystem.

Maintainer @ InfiniFlow — dedicated maintainer of the MinerU PDF/layout parser in RAGFlow (90K+ GitHub stars). Own MinerU-related issues and PRs; contributed MonkeyOCR as a dedicated PDF backend (#19044).

Products & systems

• OPENINFER — self-hosted LLM gateway with routing, guardrails, retrieval, budgets, tracing, evaluations, and an admin console. Includes oi, a hardware-aware CLI for finding and running local open-source models. Live at openinference.tech.
• netsuite-middleware — AWS middleware automation. Microservices with gRPC, event-driven workflows, PostgreSQL, Redis, and RabbitMQ for NetSuite integration at scale.
• netssuite — production-ready AI knowledge-base assistant for NetSuite. Multi-client deployment with dynamic URL generation and an embedded chatbot layer.
