Agnieszka Tomczyszyn

Otwarty i wszechstronny, utalentowany umysł, olbrzymia wiedza i doświadczenie, niezwykle dociekliwy a zarazem widzący całość projektu czy systemu analityk, integrator i deweloper. Nie znam nikogo, kto by z taką łatwością poruszał się biegle (!) w tak wielu środowiskach programistycznych i odmiennych technologiach. Doskonale się sprawdza zarówno przy skomplikowanych i rozbudowanych systemach jak i przy prostych aplikacjach potrzebnych na cito. Zawsze niezawodny. Potrafi w naturalny sposób łączyć ze sobą wyzwania technologiczne i potrzeby biznesowe. Dla Grzegorza nie istnieją problemy nie do rozwiązania. Obszar bezpieczeństwa danych i zabezpieczeń, audytów bezpieczeństwa, certyfikatów - to jedno z ostatnich zainteresowań Grzegorza, a jak już coś zaczyna zgłębiać staje się ekspertem w tej dziedzinie. Pracowaliśmy wspólnie przez 7 lat, przy najrozmaitszych projektach, niezastąpiona osoba w zespole. Praca z nim to olbrzymia przyjemność i poczucie niezawodności. Prywatnie to erudyta, niezwykle inspirująca, dowcipna i pobudzająca do rozwoju osoba. Codzienny lunch przeradza się w inspirującą dyskusję i intelektualną ucztę. Polecam gorąco!

      Diverse work as Polish Tourism Organisation promotes Poland in many ways including setting up and maintaining a plenty of websites, databases, internal and external systems which form a complex network of dependencies and data flows. Also, there is quite a number of different technologies used. My main responsibilities include: * programming and administrative assistance with websites (mostly Laravel, Wordpress, Joomla sites with heavily modified core code and non-trivial customized solutions), databases (mostly MySQL and MariaDB), IT systems (diverse technologies: PHP, Java, C# and others), webservices (SOAP), REST APIs and other communication channels; * converting and uploading data between different databases and systems - sometimes semi-manual, sometimes creating apps to automatize whole process; * creating applications from scratch (PHP, C/C++, VBA); * technical expertise in public tenders (including preparing product specifications, analyses of many kinds, business process modelling, IT consulting, court attendance in case of tender conflicts). * administering and maintaining Linux servers (Debian, CentOS) and services on these servers (web servers, databases, docker and other container services, and many others). Some notable things about my work or systems I work with: * websites, systems and databases I work with are all processing data with very variable and complex structure, multilingual (up to 16 different languages) and "fuzzy" content which leads to some interesting challenges in areas of data ETL, duplicates removal and data correction; * there is a long list of different technologies I must work with and this is a great experience to witness pros and cons of merging them all to attain the chosen goals.
