About Dennis Gaastra

I am an IT professional with 25+ years of successful software and IT projects in North America and Europe, having worked with high profile companies and forward-thinking organizations. I am a software aficionado passionate about programming, optimizing workflow processes, analyzing and solving complex problems, and finding innovative ways to assist organizations to reach their business goals.I proposed and created web-based software solutions long before they became the norm. I have always thought "outside the box" and enjoy designing creative and functional solutions that look good from the outside and inside and just work! My programming standards are high to ensure scalable long-term solutions that can grow with a company's potential future growth and needs. I am annoyed by lousy, buggy software, sloppy code, lack of documentation, and annual license fees. I am an advocate of Open Source, adherence to standardized coding practices, top-level internet security standards, and ultimately, reducing our IT footprint. I come from a family tradition of high-quality design and functionality in the bicycle industry. Our family business concepts of built-to-last, attention to detail, precision, innovation, and design elegance are also embedded in my software development and IT design philosophy. I stand behind what I create and companies that have worked with me and my team have realized one or more of the following benefits:- Reduced costs by automating routine tasks- Streamlined business operations - Improved staff efficiency through faster application run-times- Replacement of paper processes and spreadsheets through digitization- Improved reporting to meet various levels- Increased IT and data security- Reduced IT footprint- Improved communication with customers, suppliers, or partners- Continuous support & maintenance to meet current and future needsIf you are a company or organization looking for an external IT partner and interested in seeing how you can turn your IT portfolio into business success, then let's talk. It's time for companies to realize that sustainability is a key determinant of business success and should be incorporated in their IT. Let me show you how my proven analytical skills and creative flair can help solve complex design, development and deployment challenges. My personal satisfaction comes from solving problems where many others have failed before.I offer my services to you either as a consultant through my own company Gaastra GmbH or as an employee.
