I really miss working with Steve! His main software projects were clients of my APIs... we disagreed once in a while, but we were always able to explain our reasoning to each other in a constructive way to come up with solid system solutions. Steve has an amazing grasp of object-oriented software analysis and design - I am envious! He was a dedicated and hard-working employee who was always a a team player and always easy to get along with. Steve always worked hard to make sure that his software was complete, worked as designed, and was delivered on time.

It was an honor working with Stephen.
He was not only good technically but had excellent people skills and a pleasure to work with.
I highly recommend Stephen for both his technical abilities and people skills.

Pat Farina

I had the pleasure of being Steve's manager a few years ago and gained a lot of respect for his technical abilities, for his attitude and for his leadership qualities.
Steve was the kind of guy who when given an assignment strived to develop the BEST solution to the problem, solving both near term tactical and long term strategic solutions.
Steve approached every task like that, and created some really useful and elegant solutions to his tasks.
He developed a generic, reusable services for imaging code that was being developed on a large project for MBNA, something that was not envisioned by the team's architects, but was eventually enhanced to become the basis for a whole suite of imaging services that was put in place at the bank.
The thing I liked most about Steve was his energy and enthusiasm for creating really excellent solutions, in fact his commitment to excellence is the thing that stands out after many years have gone by.
It's been a while, but I hope to have the opportunity to work with Steve again in the future - it would be a lot of fun to do so.

Stephen is a highly skilled software developer. His attention to detail, time management and overall personality made it a real pleasure working with him on many projects over the last 10 years. His vast knowledge of various software languages makes him easily adaptable. Not to mention his drive and determination make him a valuable asset in any organization!

Steve is an enthusiastic, motivated and highly skilled software developer that I have had the privilege to work with twice now. Unlike many other skilled developers, he always has the customer in mind, whether that is the actual end user or another developer / development team he is interfacing with. Steve's code is clear, well documented, and guaranteed to function. He also has the highly rare quality of unit testing and system testing everything he does before he calls it done, so you know it actually is done and will work. I cannot recommend Steve highly enough and I would not hesitate to work with him again in the future.

Stephen is an experienced developer, always willing to learn more and go the extra mile. He was able to help us migrate off of legacy systems and transition into developing new features and projects that we would not have been able to do without him. In addition to the skills he was able to bring, Stephen is a great guy. He was a pleasure to work with and a valuable member of our team.

Steve's passion for software development is only rivaled by his drive to create the right solution for the problems at hand.
He is one of the few people who is able to work with end users, understand their needs, and then translate those into functional software.
