20 Years of Frontend Lessons: Architecture Decisions That Actually Matter

The Commit Your Code Conference (CYC '26)

Capital One Campus, Plano, TX View Slides (PDF)

Abstract

After two decades building frontend systems across airlines, healthcare, financial services, and government — the lessons that matter most aren't about frameworks. They're about judgment. This talk shared the architecture decisions that consistently separate systems that scale from systems that struggle: when to abstract and when not to, how to design state management you won’t regret, how to earn trust from backend teams and stakeholders, and how to lead technical direction without losing your team along the way.

Talk highlights

  • 01

    Change

    Design for the next change.

    Map likely change paths and keep their blast radius small, even when launch pressure is high. Clean code is not the same as cheap change.

  • 02

    Abstraction

    Wait for the pattern. Then abstract at the seam.

    Use real examples to discover what varies, and place the abstraction where systems change independently — not at the center.

  • 03

    State

    Keep state local and make it honest.

    Promote state only for real coordination, and model mutually exclusive states explicitly. If the model allows nonsense, the UI will eventually produce it.

  • 04

    Trust

    Trust grows when surprises shrink.

    Share risks and tradeoffs before implementation locks them in. Good direction needs trust, not just authority.

  • 05

    Leadership

    Lead with constraints, not control.

    Make the why and the non-negotiables clear, and let the team shape the how. Direction without autonomy becomes dependency.

  • Synthesis

    Architecture is the cost of change.

    Code change × coordination × confidence — five judgment calls that outlast frameworks.
