Core Skills ​

Impact Highlights ​

• Led the team coding-agent toolchain, shipping 5 shared skills (adopted org-wide in DevOps, bw rolling out to the Tech team)
• Self-hosted / open-weight LLM inference evaluation (open-weight MoE on AWS GPU EC2) + an LLM-as-judge eval loop (film-brain nDCG@5 0.93 → 0.96)
• Sole owner of the GitLab → Gitea migration: hundreds of repos, the whole engineering org, < 2h off-peak cutover
• Cloud cost optimization: EC2 RIs / Fargate Spot ~20% each, MediaLive Reservations ~50%

AI / Agentic Engineering ​

• Built a knowledge-base automation pipeline (raw → digest → semantic search / NotebookLM) integrated with Jira / Notion; shared HITL practices publicly and open-sourced the ai-kb methodology
• Self-host and operate an AI platform (OpenClaw on VPS), bringing agentic workflows into production operations
• Business foundation × AI-agent governance: a management lens on multi-agent orchestration and ops decisions — guardrails ≈ accountability controls, scoped authorization ≈ delegation, harness / loop ≈ organizational design
