Austin, TX | Get in touch through
Hello!
I am veteran in the software development field with over 30 years of experience. Using a variety of computer languages and databases, I have built software for various environments - from software for handheld devices to scan blood samples, to a system that controls access to a nuclear power reactor, to a system that sends millions of notifications a day.
I started programming, by accident, when I was 17 using a package called dBase III+. By the time I turned 20 I had already completed three paid projects - enhancements to an inventory system, enhancements to a payroll system - written in Lotus 123!, and a brand new system to track concrete deliveries.
Although I very much enjoy the programming experience, what drives me is solving problems, and the satisfaction to know that what I do helps others.
I never claim to be an expert on anything, but these days I’m very proficient using the JavaScript/Node.js and C#/.NET Core stacks. I’m also proficient using PHP with WordPres. I have worked with other languages too such as Python and C/C++, but since async/await was added, JavaScript/Node.js has become my preferred tool.
I’m also proficient in SQL in general, and the main concepts behind database performance - index vs. clustered index, for example. Since 2017 I have worked with two non-SQL databases: MongoDB and CouchDB. Non-SQL databases are awesome but are not silver bullets, and new concepts and partterns must be learned before using them efficiently.
I can work as a developer on a team, a lead developer, senior developer or even as a technical product owner.
I don’t consider myself the most eloquent communicator, but I have worked hard in developing people skills, so I can be effective translating between business and technical teams. When communicating with peers and clients I try to be empathetic and put myself in their shoes. Every day I remind myself that we all come from different backgrounds and carry different badges. I have the utmost respect for my clients because without them I would not be where I am today.
My objective is to use the whole of my experience to help your business do better. I strive to find simple solutions for complex problems by combining “what works” with shiny new technologies - where it makes sense.
