Keeping a UI Kit Updated Across Apps: Versioning, Contracts, and Trust

A shared UI kit does not fail because the button component is hard to write. It fails when five applications are afraid to upgrade it. Versioning, contract tests, release channels, and migration paths are what turn a component library from a dependency into a product people can trust.

Changing a Component Everyone Uses: Deprecation, Codemods, and No Big-Bang Rewrites

Writing the new version of a shared component is the easy 10%. The other 90% is the hundred call sites that already depend on the old one — and the fear of touching them. Here's how I change a component everyone uses without a month-long rewrite that breaks the day it lands.

Headless Components: Give Away the Behavior, Keep None of the Markup

The most reusable UI code I write renders nothing at all. Headless components, render props, and hooks-as-API are three names for one idea: separate what a component does from how it looks — and hand over the behavior without a single opinion about the markup.

Architecture-first approach

Build scalable foundations with thoughtful design patterns and clear technical direction.

Scalable UI foundations

Design systems, component libraries, and patterns that grow with your product.

Strong code quality + DX

Type-safe, tested, and maintainable code with excellent developer experience.

Team leadership & mentoring

Guide teams through technical challenges and help engineers level up.

How I work

Architecture

I start by understanding constraints and tradeoffs. Choose patterns that fit the problem, not the hype. Focus on maintainability and team velocity.

Quality

Type safety, testing, code reviews, and clear documentation. Ship fast, but ship right. Build systems that teams trust and enjoy working with.

Delivery

Break down complexity into shippable increments. Unblock teams, reduce friction, and keep momentum. Balance perfect with done.

Team

Share context, mentor actively, and foster ownership. Good code is a team sport. Invest in people, not just systems.
