(IMPORTANT FOR POTENTIAL EMPLOYERS): If I'm bidding in Your project, You can be 100% sure that i'm able to finish it in timely manner and i already have a knowledge required to make things done. I NEVER bid in projects as a part of my learning curve. Our time is really precious to us both, so, lets not waste it. I'm honest and straightforward about what i do and i require the same from my employers. (HIGHLIGHTS) I'm a highly skilled problem solver and solution architect. My knowledge comes from over 14 years of experience with development, including: - about 11 years with php/javascript/dbs (as manager and developer) - over 4 years with nodejs - over 3 years with GO - almost 5 years with freebsd - over 7 years with simple and/or distributed scrappers/crawlers (php/python/nodejs based workers) - high and low level scrappers! So i can - but don't have to - use things like selenium to scrape ANYTHING. I don't use buzzwords, so if You are not sure if i can do what You need, just ask!

He signed up for what he thought was an easy task, but it ended up being 5x harder. His creativity and resourcefulness gave him the ability to get the job done when most programmers would have failed. You will not go wrong hiring Krysztof.”
