Hi, I’m Simo
I’m a Software Architect with 15+ years of experience in the trenches of backend engineering. I’ve spent my career building scalable systems and solving complex architectural puzzles.
I wrote some free courses for learning web development. On this website I share my knowlegde and everyting I have learned in programming so far.
Look bellow some of my free courses.

Preparing for a PHP Interview?
I’ve interviewed over 200 PHP developers in the last 2 years. This course is everything I ask — and everything you need to know. 1000+ questions covering PHP, Laravel, Symfony, databases, architecture, security, and more.
Preparing for a Javascript Interview?
JavaScript interviews are unpredictable. Closures, async traps, framework quirks, runtime behavior – interviewers love catching you off guard. This course covers the full spectrum: vanilla JS, Node.js, React patterns, and the tricky questions most candidates stumble on.

Symfony Bundle Features
Part 12 of 13 in the PHP Package Development series This is it – the final post.

Laravel Package Deep Dive
Part 9 of 13 in the PHP Package Development series In Part 8, we covered the fundamentals of Laravel packages – service providers, config publishing, package discovery, views, and routes. That’s enough to get a package working, but Laravel offers so much more. Facades, Blade components, custom Artisan commands, migrations, middleware – these are the…

Laravel Packages Basics
Part 8 of 13 in the PHP Package Development series For the first seven posts in this series, we built jakovic/text-toolkit – a framework-agnostic PHP package. It works everywhere: plain PHP scripts, Laravel apps, Symfony projects, wherever. And that’s the right approach for core logic. But if your users are mostly Laravel developers, they expect…

Advance Package Patterns Part 2
Part 7b of 13 in the PHP Package Development series In Part 7a, we covered the Strategy pattern, Driver/Adapter pattern, configuration objects, interface-based extensibility, and the Builder pattern. These give your package solid architecture. Now let’s make it truly pluggable with runtime extension points – middleware pipelines, event hooks, service container concepts, and a complete…
