You are a developer of a large legacy application, into which you are gradually introducing PHPStan. You start with level 0, which is quite challenging, but eventually you get it right.

A story from the end of 2016, when I was literally saved by a colleague: in a PHP application, you decide to check in images via a proxy script, which, among other things, can adjust their dimensions and other parameters according to the incoming request.

After 3 years, your hosting provider suddenly tells you that they are increasing the price by 50% next month due to an increase in energy costs. When you negotiate over the phone, their manager just tells you that you either accept the new terms or they will have to say goodbye. If it's just your pr…
You and a junior colleague are developing a custom e-shop as an FTFP job (fixed price, fixed time). You have all the template graphics, coded homepage and product detail ready. Junior colleague can only use Nette and Latte, the level of coding knowledge is rather average. But you heard about React a…
PHP mám opravdu rád, protože umožňuje velmi rychle dosáhnout cíle a udržovat elegantní kód. První PHP aplikaci jsem naprogramoval před více než 10 lety, a od té doby se PHP stalo jedním z mých nejoblíbenějších jazyků.
Za tu spoustu let se PHP hodně posunulo, proto na tomto webu najdete spoustu postřehů a triků, jak řešit problémy elegantně. Taky si můžete pročíst série článků, zkušeností a dobře míněných rad, které pomohou zásadně zlepšit Vaše webové aplikace.
Poslední 3 roky kariéry se věnuji převážně návrhu softwaru, architektuře, tréninku vývojářů, konzultacím a školení s cílem zlepšit návrhové vzory aplikací a odhalit úzká hrdla konkrétního projektu.
