I am a software engineer who likes understanding systems deeply, from AI agents and product workflows down to computer fundamentals such as compilers and operating systems. My work combines production engineering, high-performance systems, and long-form technical research.
- Current work: AI Agent engineering. I build production-grade LLM applications, with a focus on agent runtime architecture, memory and context systems, planning, evaluation, observability, and workflow reliability.
- Previous experience: Data R&D and data platform engineering for large-scale user profile systems, covering high-throughput backend services, data pipelines, permission systems, and platform reliability.
- Research interests: AI Agent systems, programming models, context engineering, memory systems, LLM product architecture, compilers, operating systems, and how software engineering changes with AI.
- Writing: I publish public essays on AI engineering, Agent design, programming languages, and the evolving craft of building software.
