I am a programmer located in Poland. I (try to) develop: cool websites using modern frameworks like Vue, weird Python bots and scripts. In my free time I like to pretend that I own a company.

About my (non-existent) company

  We here at jcubed have come to know that it is better to reintermediate nano-strategically than to embrace nano-micro-intuitively. We pride ourselves not only on our back-end, intuitive, viral feature set, but our simple administration and simple operation. Your budget for growing should be at least one-third of your budget for engineering. We apply the proverb “Like father like son” not only to our synergies but our power to optimize. If you revolutionize compellingly, you may have to streamline iteravely. If you synergize mega-holistically, you may have to facilitate robustly. Do you have a scheme to become user-defined? Imagine a combination of HTML and COBOL. We will visualize the term “bricks-and-clicks”. We have come to know that if you iterate globally then you may also architect super-ultra-mega-virally.
