What I do
WordPress plugins, themes and custom apps!
My main focus over the last 5 years are custom WordPress / Woocommerce solutions. This includes crafting themes from scratch, implementing solutions with the majority of the most popular plugins and creating custom ones, creating rest API based apps / SaaS model, doing security audit, speed optimization and reducing server recources. The list is long, so if you have something challenging just ping me.
Laravel, Codeigniter, you name it!
If you want 100% custom PHP application then using some popular MVC framework is a must. I have experience with many of those PHP frameworks, but my best bet is always Laravel.
