About Alex Beattie
Senior AI/LLM engineer and founding engineer focused on scalable Django/Python backends, production AI systems, and cloud infrastructure for healthcare products.
My recent work spans backend architecture, AI health tools, AWS optimization, GraphQL APIs, and Flutter-connected mobile platforms. I focus on systems that are reliable, observable, cost-aware, and practical to operate after launch.
In AI systems, I care most about the pieces that make products dependable after the demo: routing, grounding, source metadata, Langfuse evaluation loops, Strands agent behavior, observability, and operational controls.
Recent work includes:
- KiNDD / NDD Resource Navigator: founder/engineer nonprofit startup platform
- Unified Connectors MCP Server: IDE-native engineering context across GitHub, Slack, Jira, Confluence, Google Docs, and Miro
- Cost-aware model routing, token analytics, and budget-aware AI system design
Background
I have 14+ years of experience shipping software across mobile, backend, cloud, and AI systems. I started in Swift/iOS, moved through TypeScript and Node.js, and now work primarily in Python, Django, Postgres, AWS, and LLM infrastructure.
Before moving into healthcare AI, I spent 13 years as the sole technologist at Sherwood Development Company, where I owned software, automation, web systems, integrations, and technical operations end to end.
