Skills and Recent accomplishments
Most recently, for the last year I have been working in rust designing and developing a backend api.
Enabled analytical instrument communications by designing a client side C# framework using Visual Studio. Framework embodies an instrument abstraction that allows client developers to easily access an instrument. Work extensively with Linux command line to build and troubleshoot instrument communications.
Designed instrument user interface in Java 1.7 and using Netbeans IDE 8.02. Framework allows instrument developers to create instrument specific user interfaces that encapsulate consistent behavior and company branding.
Design and prototype instrument enterprise communications that incorporates a message broker ( NATS.io ) and protocol that allows for instrument and lab equipment discovery, identification, and addressability. Wrote reference class libraries in C# that encapsulate design and protocol.
Develop prototype full stack web application to access instrument using enterprise communications comprising of node.js libraries on the backend ( NATS.io client, feathersjs services ) and react.js and vuejs on the frontend.
Develop prototype iPhone and tvOS applications in objective-c and swift. These applications demonstrated how to interact with instruments using enterprise communications.
Part of an ongoing effort to provide scripting abilities to our flagship application using google blocky and python. Interface consists of a C# api and generated python code to script the application. Responsible for the python code generation in javascript and general python coding and investigation.

I worked with Steve at TA Instruments as a fellow software engineer. I benefited immensely from his deep knowledge of software engineering and his willingness to share such knowledge with his fellow engineers. Steve is extremely competent in a myriad of programming languages and frameworks. He was the technical lead in several .NET, Java and iOS
projects we had at TA Instruments. He will be a great asset for any organization.

Amazing Software Engineer who is extremely enthusiastic about his work! I have had the pleasure of working with Steve for the 3 years I was at TA Instruments. He is a brilliant engineer who is customer obsessed and focuses his energy to delivery high quality products that are designed with the user in mind. He is constantly trying to innovate with new technologies to improve our services. I have always admired Steve for the energy he brings to room and his work ethic. He is super helpful and has always given me good feedback on my work and helped me debug some hard problems. and He is an excellent team player and an amazing person to work with.

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.

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.

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.
