Sterling Chin stopped thinking of AI as a tool and started treating it like a junior employee. Onboarded it with context, corrected its mistakes, and gave it writing rules.
Forty days later, MARVIN was handling 90% of his workday.
In this episode of Chain of Thought, Sterling (Applied AI Engineer and Senior Developer Advocate at Postman) walks through live demos of MARVIN, his personal AI assistant built on Claude Code. From pulling meeting transcripts and updating Jira tickets to drafting blog posts and managing his calendar, MARVIN runs as a full-time AI chief of staff.
We cover:
- How MARVIN bookends Sterling's workday from first login to the end of the day
- Personality, sub-agents, and writing rules that make MARVIN an effective co-worker
- Automating meeting notes to Jira tickets
- Why DIY assistants outperform big tech alternatives
- How Sterling onboarded 12+ colleagues at Postman, including non-technical knowledge workers
- What the compute crunch means for open source AI
