About

I’m Simon Aron, a full-stack software engineer focused on building B2B products and AI systems end-to-end. I work primarily with Ruby on Rails, React, TypeScript, and PostgreSQL, and I enjoy owning features from early product decisions through delivery, testing, and iteration with direct client collaboration.

In my recent work I’ve built AI-first systems such as sandboxed AI agents with tool execution, retrieval/agent workflow improvements, and low-latency real-time messaging. I also implement practical engineering concerns like RBAC, approval flows for state-changing actions, and efficient integrations—turning AI capabilities into reliable, production-ready products.
