When an Agent Should Ask Instead of Acting
Autonomy is not a single setting to turn up. A useful agent knows which decisions it owns, which ones it can reverse, and which moments need a human before the next step.

Tools Are Part of the Agent's Intelligence
An agent cannot reason about information it cannot reach, and a vague tool description turns a precise capability into a guessing game. Tool design is not plumbing around the model. It is part of how the agent thinks.

The Context Is the Product
A capable model with the wrong context is still a bad agent. The useful part of an agent is not the model in isolation, but the project knowledge, rules, tools, and decisions that shape what it can see before it acts.

I share frontend news and the reasoning behind it throughout the day. Pick the language that feels natural to you.
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.
