A DEVELOPER WHO SPEAKS HUMAN.
My name is Mariusz Kardaś, I'm a frontend developer - Rescoder is my company. I design and build web apps, mobile apps and business websites: I run the project from requirements analysis all the way to production, so responsibility for the result always stays in one pair of hands.
Code is half the job. Before writing anything, I break your problem down and tell you straight what actually makes business sense - no jargon. I work remotely, on invoice (B2B): you need an app, you get a working app.
And when a project needs backend work - a CMS, a configurator, API integrations - I deliver that too, without handing the work off to someone else.
