How do I approach a new project?

I start by identifying the constraint that cannot be negotiated — a latency budget, a security guarantee, a payment method, a network quality. The architecture follows from that constraint, never from a stack chosen in advance.

Why do I favour server rendering?

Because a page whose content only exists after JavaScript runs is invisible to some users and to most agents that read it. Server rendering is an accessibility decision before it is a performance one.

What is my stance on complexity?

An abstraction earns its place with a second real use case, never an anticipated one. I have regretted generalising too early far more often than duplicating once.

How do I work in a team?

I write architecture decisions down before the code, so they can be challenged while they are still cheap to change. Documenting a decision is worth exactly the time it saves the next person who reads it.
