I've been analyzing, designing, and developing software applications in varied environments for over thirty years. Most of these environments integrated a GUI or Web-based front-end with a relational database on the backend. I've also configured and managed systems and networks, and consulted with clients on these issues, at need. My experience in database, system and network administration help me make design choices to avoid conflicts and performance problems due to backend bottlenecks. Most recently, I've been highly involved in the development and support of multiple highly-available, web-hosted applications utilizing web, Windows, Android and iOS client devices with clustered, redundant Microsoft SQL Server instances as the data store. Backend processes were performed by T-SQL jobs and Windows services and application written in VB.Net and C#.

Solve business problems (POS, Onboarding, Payment Processing) with custom .NET C#, SQL and API integration with 30+ years of running a business. Reduce total cost by better managing the process. I solve business problems through consulting and custom software. I provide not just software development but also management consulting and project management. By better managing the project, I help you make more profit at a lower total cost of ownership. I deliver systems that work - under load, can be certified per regulations, with data security, and that users can use. And I do that at a competitive total price with fewer headaches. I've had clients repeatedly bring projects back to me to get them to work after trying cheaper people. I've taken over projects that other developers left unstable and made them stable. My goal is to provide you with the highest quality, most innovative software solutions to your business problems. I bring over 30 years of experience to bear on your problem so that you get the best solution that fits your organization. I am currently working on a forthcoming book, "Business - a Spiritual Journey". Over the last year, I reworked multiple e-commerce sites for a client, cleaning up many bugs, redesigning the codebase to support multiple groups on a single site, and finding and solving several ways that fraud had happened on those sites. Previously, I took over an Oil and Gas Investment database that was not working. I got it working again and added several functions making the team far more productive and better able to find the customers they need. In the last few years, I designed and built a debit processing web server that is being rolled out to 100's of stores. I designed and built my own Gift and Loyalty card processing system that has been sold to several clients. Since I own the IP, it is available for customization. It supports web as well as mobile and POS terminal interactions. Together with another person, we redesigned the business processes for a payroll forms processing company where we redesigned the database, rebuilt the desktop application, designed and built a remote web site that allows people to fill in the forms in the field and upload to their database, and certified a new communications channel with the state. This has cut the human work load significantly so that the company is able to go out and get new business without expanding headcount. I designed and built the interface between a POS system (Aloha) and an accounting system designed for amusement parks (Core) so that they could use their own gift cards at that amusement park. I have written numerous credit and debit applications and certified them with the various processors. Many of these were done in C# and against SQL Server or SQL Azure. I've worked with AngularJS. Yes, other people will test out better on the technical details of any language. Other people will design prettier user interfaces. I build systems that work. They work under load. They work in multi-threaded / parallel processing environments. They work in hostile environments where hackers are trying to steal data. I write simple code that solves complex problems - simple and documented code that other people can pick up, read, understand, and modify. I write reusable code for libraries and reusable systems that can help multiple clients. My (1 man) company is a Microsoft Partner and has been in business since 1991. D&B Number available on request.
