    Jacek was crucial in helping us figure out our system and identifying areas for improvement. He's speed and willingness was only surpassed by his ability to code. Even though he had to leave the company, he trained another developer of equivalent skill set to replace him as Lead Developer - the replacement is transitioning well and we hope to finish the project on time and budget.
