Approach
What I bring to a team
I work spec-first and AI-native: coding agents generate code and tests from the spec, and I own the architecture, the review and the quality of what reaches production.
Architecture and delivery
Full-stack TypeScript with NestJS, Vue and React, and data models built for multi-tenancy, payments and real time. Scope turned into shipped product.
AI systems in production
LangGraph agents, retrieval on Qdrant, tool calling over MCP, fallback across model providers and token costs measured per customer.
Engineering leadership
Roadmaps from business requirements, code review, zero-downtime releases, security audits and incident response.
