Marek Bogatek

Fullstack developer with inclination towards non trivial problems

Poland - Tests: 9 - Portfolio: 1

I am a wizard. Seriously. I use rare combination of talent, skills and hard earned knowledge and experience to solve others' unsolvable problems. Wonders and miracles done immediately, impossible stuff with minor delay. Upwork is an opportunity to learn more and faster, and get myself involved in much more interesting, diverse projects that I would thought possible previously. Such cases were, for example, helping Panama based company OSOP with systems they use to predict (and provide warnings for) earthquakes in mid-America region; or a web crawling problem that was neglected by everyone passing through the Chegg Courserank project (creating the general solution for this took me to senior engineer position... and further, to team management); lately I was able to provide candidate and code reviews and design basic specifications for entirely novel software - and surely, such contracts showed up as well. You can see some of my previous private/hobby projects on github: ... and some social programmer activity at stackexchange sites under the same 'zencodism' login. So far, I've created numerous utilities and scripts (C / C++ / Python), a complex image manipulation and postproduction suite (C++ / asm / CUDA, worked on this as a member of a team), some visualisation software: for custom equipment (Java) and voice emotion recognition (Node.js), and a few web based projects (Python with Django, PHP, Perl, Groovy - working with a team on huge CRM system) including also long term contract regarding Java-based web scraping suite I both developed and managed the team involved. Further down the road I'm turning to web applications along with their server counterparts - everything from designing communication protocols with cryptography and some redundancy to a space simulation game I'm writing as a hobby. I can work in and administer various operating systems (Windows, Linux, *BSD, Solaris... this came in handy lately when web development job turned into disaster recovery of remote server), use several databases (mySQL, PL-SQL) and quite a few programming languages; even created one myself, just for fun. What will be next, may be up to you. Feel invited.
