AI-native engineering
Building with AI
Claude Code every day. I write agentic AI workflows that take work from ticket to merged, tested code — and I own what ships.
Plan first, then build
Agents propose trade-offs before code. I decide; they build in small steps.
Agentic workflows
Multi-agent workflows, custom skills and rule files that encode team standards.
Connected tooling
MCP links agents to tickets, designs and GitHub.
Tests as guardrails
Tests, coverage gates, CI and secret scanning on every AI change.
Human-reviewed
I review every diff. AI adds speed; I own what ships.
Helping teams adopt AI
AI workflows for iOS teams that are fast, safe and consistent.
