Full-Stack Engineer · Devtools Builder · Webhooks/API Tooling · AI-Agent Workflows · Automation Systems
I'm a full-stack engineer and solo builder focused on developer tools, agent systems, workflow automation, webhook/API infrastructure, and performance-conscious software.
My work sits at the intersection of:
- Webhooks and API tooling: capture, inspect, replay, forward, validate, mock, and secure traffic.
- AI-assisted development workflows: reusable agent assets, host-aware activation, MCP/design-to-code workflows.
- Automation systems and internal tools: practical utilities that remove workflow friction.
- Reliable product engineering: understandable architecture, security-sensitive defaults, and performance-aware UX.
- Open-source launch proof: docs, technical writing, HN/Product Hunt surfaces, and useful public artifacts.
