Apply an AI-first philosophy to the design of architectures, processes, and tooling integration throughout the development lifecycle. Architect and integrate AI/LLM-powered solutions using frameworks such as LangGraph, LangChain, and the Anthropic and OpenAI SDKs. Define data architecture strategy across relational and non-relational stores (PostgreSQL, MySQL, MongoDB, Redis). Establish and enforce best practices for code quality, CI/CD, containerization, testing, and system observability. Drive technical roadmap planning, balancing long-term architectural vision with near-term delivery priorities. Conduct architecture and code reviews, providing clear technical guidance to development teams. Evaluate and introduce new technologies, tools, and patterns that improve engineering velocity and product quality. Collaborate cross-functionally with product and stakeholders—communicating in English when needed—to translate business goals into robust technical solutions.
