Fintech
US consumer lending, today
Staff engineer with 10+ years shipping production systems. I work spec-first, with agents, and still ship code every week. The LLM advises; deterministic checks decide.
AI 1 // _llm-feature-in-production
IoT analytics SaaS platform for HVAC and refrigeration
Technicians get grounded descriptions built from telemetry the platform already has, in the report's format.
view-case-studyAI 2 // _agent-readable-knowledge-base
An engineering organization
Agents and engineers share one source of truth that stays current, and AI review became a standing control.
view-case-studyAI 3 // _mcp-servers-and-agent-infrastructure
An engineering organization
Agents get real context without leaked keys or over-broad permissions.
view-case-studyAI 4 // _agent-skills-for-a-lending-team
Splash Financial, US consumer-lending engineering team (current role)
Shared agent skills the team uses, and delivery where every ticket traces to a committed spec.
view-case-studyAI 5 // _governance-for-ai-assisted-engineering
An engineering organization
Deterministic checks decide; the LLM advises. Merges stay gated by checks that behave the same way every time.
