Hi there! If you’re reading this, you’re likely considering me for a position with
your team. Thank you! Here’s a little more about me. I come to you with over 25 years of development experience, including tenures in executive and supervisory positions, project management and product ownership skills in Agile, Scrum, and other methodologies, and an extensive software architecture background. I’m also an expert marketer and writer, an experienced OEM manager, a competent salesperson, and a decent human. I’m searching for an opportunity to make a huge impact for an organization that will value me as much as I value it. I prefer to stay with companies for the long haul, learning every role in the company that I can and pairing that knowledge with my experience to identify clever solutions and deliver a ridiculous amount of value. Pretty much every organization I’ve worked for has promoted me, often to newly-created positions crafted around my unique skill set, for one simple reason: I am constantly seeking opportunities to do more to help my team win. I’m a master of PHP, Java, and SQL, with a fair amount of experience in C++, familiarity with several other languages, and an eagerness to ninja-quickly absorb other technologies as warranted. I’m a strong advocate of clean and LEAN code, standards compliance, security- and best-practices-first architecture, and API-driven design. Unlike most developers,“docs” is not a four-letter word to me, but “impossible” is. I thrive equally as a lone developer or part of a Scrum team, and I’m no stranger to thought leadership. To me, every feature request is an opportunity to better understand and evolve the application by resolving the “root why” of the request rather than just mindlessly doing the bare minimum to close the ticket. I do my best, in everything I do, to embody the Scrum values of respect, openness, focus, commitment and courage, whether or not I am actively working on a Scrum team.
With me on your team, you will immediately feel my impact as a vocal advocate for doing things right the first time and building things that last, and you’ll quickly see me leading by example on those fronts. Together, we’ll find new and creative solutions to the problems you’re trying to solve. I’d welcome an opportunity to interview with you at your earliest convenience, so you can tell me about the kinds of challenges you’re facing and we can formulate a strategy for combining my experience, passion, and talent with your existing team in order to crush your backlog.
As someone who has made a career out of automation, I appreciate more than most just how precious human bandwidth is. Thank you for spending some of yours looking over my application and credentials. I look forward to making that investment pay off for you soon.

What My Teammates Say…
Danny Lott Reports to me add63v@r.postjobfree.com
“Matt is one of the most ambitious, industrious, and straightforward people I have ever had the pleasure of working with. If he believes in an idea he will not stop until that idea is the best reality it can be. Matt is a direct communicator. He gets to the heart of an idea as neatly and directly as the code he writes. There is no one in this world I would trust to find any inefficiency or error in anything I’ve created more than Matt. As a supervisor, Matt is understanding and compassionate. He sets reasonable expectations, provides the resources needed to meet them, and is encouraging without being encumbering. You always know where you stand with Matt and know that he will do whatever it takes to help his team achieve their greatest potential.” Woody Hutsell Customer / guild member add63v@r.postjobfree.com I met Matt through my involvement in the board gaming community and Matt has selflessly guided our business through some difficult choices. What is more impressive, is that he provides these same services to hundreds of other independent game developers. He has done all of these things in his spare time while serving full-time as a software developer. You can see examples of his development skills on the website for the indiegamealliance.com.If you are looking for someone with commitment, integrity and dedication I could not imagine a better option.

Joe Still Direct Supervisor add63v@r.postjobfree.com
“I enjoyed my time working with Matt, and have always been fascinated with his experience and side projects. He is a valuable asset with a wealth of experience from past work and his side business, basically single-handedly generating a complete digital experience platform to empower board game creators to deliver their work. He is honest, with himself and others, dependable, and really cares about his work. He is vocal, offering constructive criticism of solutions to ensure they do not compromise effective security or performance considerations.
Along with his undeniable talent, Matt has always been an absolute joy to work with for me. He developed additional skills during my leadership, is a true team player, and always manages to foster positive discussions and bring the best out of other employees. He wants to do things the right way and not cut corners or compromise on what is possible or necessary to solve the real job to be done.”
Robert Schwyzer Peer (Solutions Architect) add63v@r.postjobfree.com
“In every conversation and interaction, Matt fully demonstrated his vast knowledge of software engineering and how his role relates to the larger business and towards improving customer satisfaction. Matt made proactive recommendations and intently participated in discovering as much as he could about the situation, the customer impact, and the business goals to further productive collaboration. also appreciated Matt's architectural expertise and emphasis on component modularity. Matt did an excellent job identifying maintainability and expandability problems with the legacy systems handed to him, and he designed and enacted team execution on excellent plans to address these concerns. This made Matt's productive collaboration even more valuable as it enabled us to ensure the solution followed his larger design goals so the solution could benefit down the road from those maintainability and expandability improvements. You would be hard-pressed to find a more valuable addition to your software development team than Matt.”

What My Teammates Say…
Jason Clark Peer (Database Administrator) add63v@r.postjobfree.com
“I have known Matt for a number of years, we became acquainted while working together at Smartwerks. Being in the data space (Database Administrator), I leaned on him heavily to understand the application side of development and operations. I can without a doubt say that insight like that has helped me further myself in the IT industry. In his career, Matt has designed everything from video games to Internet applications. His passion for technology, gaming, and often a combination of the two, is commendable. In the years we worked together not only did he excel at his duties as a developer within the company, he also excelled at developing a company and online community (in his free time) that assists an ever-growing amount of struggling board game developers finish their vision. Drive like that is not easy to come by.”
