hi, I build software.
I'm Weng Jialin, a software engineer building AI Agent infrastructure and developer platforms. More about me →
The Next Layer of Agent Observability
Why agent observability needs to connect semantic traces, system-level facts, agent gateways, OpenTelemetry, evaluation, and policy into one governable trust chain.
Formal Methods × AI Coding
Why AI coding's prompt-level specs organize work but do not verify complex system design, and where system-level formal methods like TLA+, P, and runtime conformance checking fit.
Harnessing AI Agents: The Design and Evolution of Harness Engineering
A comparative analysis of seven AI Agent projects, examining the Harness design space across loops, tools, sub-agents, context management, permissions, and enterprise adoption.
The Real Bottleneck in AI Code Review
Why AI code review succeeds or fails less on comment generation and more on context supply, trust, and the shared intelligence layer between developers and agents.
