// process
How we play it.
Three phases, borrowed from the game the company is named after.
Scope fast, take the center
Establish the problem, the users, and what success actually measures — before a line of code commits you to an answer.
Build in short cycles
Ship working software on a rhythm you can see. Tactics over theory: the running system is the status report.
Convert the advantage
Iterate, tune, and maintain. A launch is a position, not a result — the value comes from what happens after it.
// operating model
Simple systems, maintained on purpose.
E4E5 LLC favors small surface area, fast-loading experiences, and focused software that stays maintainable without accumulating complexity nobody asked for.

Why “E4E5”?
1. e4 e5 is the classical reply — the most direct answer to the most direct first move. Both sides claim the center immediately and develop with purpose.
That is the operating philosophy of the company: take the center of the problem early, develop deliberately, and avoid clever complications that don't improve the position.
