Platform Engineering × AI: From Refactoring to Reliability

Join us for “Platform Engineering × AI: From Refactoring to Reliability,” an evening exploring how AI agents, deterministic codemods, and supervised automation are reshaping large-scale engineering workflows. Hear real-world stories of shrinking multi-year migrations into months, transforming fragile legacy code into evergreen systems, and saving hundreds of developer hours with AI-powered codemods. A meetup for engineers who want to move beyond writing code—into orchestrating intelligent systems that write and improve it.

From 8 Years to 6 Months: Orchestrating AI agents for Large-Scale Refactoring
Refactoring a massive legacy monolith is every developer’s nightmare—especially when estimates hit 8 person-years. At monday.com, attempts to rely solely on Generative AI introduced hallucinations and drift, pushing us to rethink automation entirely.
In this talk, we’ll show how we cut the migration timeline to just 6 months by building a custom orchestration engine combining agentic coding with deterministic codemods (AST). You’ll see our “Research-Execute-Review” workflow in action, where a Node.js orchestrator manages autonomous agents that validate their own code through custom validators, linters, and tests before a human ever reviews a PR.
We’ll share the governance patterns, oversight strategies, and orchestration framework that enabled us to eliminate years of technical debt in months—while maintaining full stability and zero production incidents.

Saving 1000+ developer hours with codemods
Moving from one major version to another in various repositories is a tough task that might take precious hours of your time.
To put it delicately, I hate manual work. Facing the excruciating process ahead of me, I decided to build a tool to help me in migrating huge amounts of code from one version to another. In this session I will share the reasoning for this project, the technicalities behind it, how to use AI to generate migrations, and how to use this tool for your own benefit.

From Legacy to Evergreen: Supervising AI Agents for Confident Coding
Are you spending much of your time wrestling with untested, fragile legacy code? AI agents promise an easy escape by instantly generating and refactoring code. They even seem to offer test coverage. Yet using them unchecked results in low-quality "legacy code" that is just as painful to maintain as, well, legacy code. In this talk we will talk through a "Small Step" methodology for effectively partnering with your AI agent: we'll break down complex modules into manageable chunks, guiding the agent with precise prompts to focus on the public interface and business logic, not implementation details and even a way to automatically make sure no regressions were made during a change. You will walk away with a proven, practical framework for supervising AI-driven Coding. It will allow you to confidently transform old, undocumented systems into evergreen code with a robust test suite that prevents regressions, accelerates refactoring, and dramatically boosts development velocity.
