Having worked as a programmer, hardware designer, and manager, I have both the technical skills and the business expertise to help you achieve your goals with a project. In addition, my years of experience have helped clients avoid the disasters that software projects can easily become. I have been involved with projects that significantly increased the number of calls a tech could handle, reduced returns by more accurately tracking similar failures and suggesting additional steps that need to be taken. Clients have seen improved profits, reduced complaints, and fewer problems as a result of software I've written. I know how to design a project from the start to reduce the overall cost, and how to analyze requirements to ensure that the software can achieve the desired goals. Major projects have included a complete Repair Tracking and integrated accounting package for a Depot Repair facility. Repair tracking, which integrated with a separate accounting package and UPS and FedEx shipping programs. A Call Log tracking and issues database for a Tech Support Center, and a Job and Services management tool for a Landscaping firm. My C++ work has included projects that interface with other proprietary hardware, printers, RFID readers, and other devices. I have also completed projects using C, Assembler, and embedded software. (My combined hardware, software, and business skills background enable me to tackle a wide range of projects.) I've been involved in more small projects than I could possibly remember. Since my first Fortran program in college (I have a BS EE from University of MO at Rolla) until now I have worked with many languages and know how to match the tools to the project to get a best fit. My skills include VBA (Microsoft Access since 1995), C++ (Since 2000), and Microsoft SQL Server. Plus, I've kept my skills updated through reading, the web, and personal study.Microsoft SQL Server Programming

Certifications: AZ-204 Azure Developer; AZ-900, Azure Fundamentals; DP-900 Azure Data With over 25 years of experience as a software developer, I’ve had the opportunity to work with .Net since its inception in 2001. Having seen the progress made in the technology along with the ability to leverage the improvements and iterations, I remain passionate about .Net technology and architecture as I continue to explore and grow in my career. Some of the technologies I use are many Microsoft Azure services, Entity Framework, HTML5, CSS3, Bootstrap, JavaScript (including several libraries), C#. .Net Framework and .Net Core, and .Net 5.0. I'm not much of a designer so I keep designers and graphic artists handy. I say stay with your strengths. My credentials include positions as architect, coder, lead developer and now a full-time freelancer. By expanding my knowledge and leading by example, I have a proven track record of getting the right results. My style is very hands-on with project management and planning using Agile. I’ve acted as a Scrum lead and kept Kanban boards up to date to create and maintain an efficient workflow. My education and business experience have provided me the discipline of having a bias towards cost-effective solutions. I have an MBA from Kennesaw State University just north of Atlanta, Georgia. Because of that, I approach all work from not only a technical side but also understand that you are a business and are looking for great value. So my approach has a business bias. I manage projects through Azure DevOps for project tracking, repositories, and builds. I would recommend that we use Microsoft Azure for hosting. You can find hosting cheaper, but you won't find a better, more diverse, or more secure platform. I'd be happy to talk to you about your project, find out your needs, and give you my two cents worth of advice even if you choose to use someone else. I have also most recently been working with Wappler and the no-code tool. I'd highly recommend that you check it out. I hope to work with you soon.
