Hi. I'm Jason - an experienced (25+ years) software architect and engineering professional involved in all parts of the SDLC (Waterfall, Agile and Hybrid methodologies).
With a wealth of experience across industries such as commercial aviation, banking (real-time payments processing & FX), 24/7/365 manufacturing lines, e-commerce, and public transport (smart card), I will bring a passion for delivering elegant and reliable solutions to your project. I will work with you (and your team) to provide the best possible technical solution to your business problem.

This is what my 25+ years of experience bring you: honest, robust, and intelligent solutions to see you succeed.
When asked to build software, I deliver high-quality server-side C# .NET software solutions that give what you need: Software engineered to be robust, scalable, and designed to exceed your business expectations.

⭐️ Clear, effective communication
⭐️ Precise, quality recommendations to ensure success for your project
⭐️ A focused, collaborative approach to work with you and your team
⭐️ A no-nonsense, results-focused approach that delivers value to your project
For example, this are what a couple of my clients had to say:
❝Jason is by far the best architect I have ever worked with. He displays extreme ownership of his work and it's incredibly refined. Every deliverable was on time or ahead of time. Not only did Jason provide an incredibly performant and scalable architecture, the documentation he provided was top notch.
I will forever keep Jason and my goto for any and all technical and solution architectural needs.❞
Cade - VP Engineering - US Software Company
❝Jason helped get our team on our feet for doing proper documentation and much more, actually. He helped improve the engagement of our team members and how they work together. If we can, we will surely ask for his help again in the future. I can only give high praise of Jason's quality of work. We highly recommended for documentation and general architectural design work.❞
Alexander L - Acting CTO - Global On Media
