“ Piotr is a great developer and highly skilled His work is always high quality and delivered on time. It's a pleasure to work with him. ”
“ Piotra, jako programistę wyróżniają dwie cechy, które z pewnością zasługują na uznanie. Pierwszą jest szukanie najlepszego, docelowego rozwiązania. Stara się realizować zadania w taki sposób, aby przygotować funkcjonalność "na lata", nie "na chwilę". Drugą jest zrozumienie biznesu i umiejętność przełożenia technologii na biznes i odwrotnie. Serdecznie polecam Piotra, jako doświadczonego programistę. ”
