AI tooling

I use AI where it makes engineering faster and decisions clearer, while keeping architecture, review and product judgment human-owned

Scoped implementation, refactoring, test generation and review with coding agents

Source-grounded exploration, rapid comparison and structured technical decisions

Repeatable workflows, MCP integrations and reliable handoffs between tools

Local LLM integration, model lifecycle, inference UX and device-aware performance
