If you are reading this, it probably means you are one of the two frequents who keep running across the profiles maintained at this site. 1) the person who wants to know what a killer profile looks like. 2) the seeker of an equal, if not a better, to tackle that pile of responsibility towering ahead of him/her, so s/he could, let me guess, watch that new video of a cat in action or catch 'em pokemons? Congratulations, if you are one of the two! You have just uncovered the real deal and by suffering this far along, shown a great deal of endurance to my cocky sense of humour. The future hirers would, by now, be wondering if I am actually that good and not wasting their time. If good highlights the fact that I have a command over English language, then I'm better. If good demands prior experience in writing, I can present to you a pyramid of job well received from my past employers. It includes an array of responsibility, however, revolving around writing and editing. It also includes a panel of platforms ranging from blog writing to creative writing and everything in between such as article writing, technical writing, travel writing, and business writing. If good requires me to be a trusted partner, I can deliver. Professionally, I am a software maker and technical writer. I know that business needs more than words to foster. It needs ideas. Not overdone or dull. But simple and electrifying. If you choose me, I will make sure that your business grows beyond par with my sorcery. If you are asking can all this magic actually be affordable, you bet, it can. And, if you are still figuring out the spells that I can cast, would you hire a sorcerer without checking out the spells they can cast? Here is a list of my spells. I. THE INFRASTRUCTURE (Docs-as-Code) Workflow: Git-based workflows (Pull Requests, Reviews, Merges). I treat words like code. Editors: Whatever IDE your devs live in.

FLUENT IN (Domain Expertise) The Tech: Observability, AI / LLMs, Cloud Computing (Azure/AWS), Cyber Security. The Code: I read Python, C#, and VB well enough to explain it to humans. IV. THE "KEEP YOU OUT OF JAIL" SUITE (Compliance) Standards: ISO 27001, SOC2 preparation, and general regulatory compliance. The Goal: Auditors love me. Developers tolerate me. I have been active in industry standards activities, and my research and consulting has specialized in software portability and interoperability. I have experience in a broad variety of domain areas including betting systems, retail logistics, enterprise architecture, legacy applications, security, operating systems, AI systems and reporting systems. Besides my profession, I enjoy movies from around the world. I also consider myself a great Batman: Dark Knight aficionado and after a hard day's work, find great satisfaction in playing guitar to a baby turtle. One final note: I don’t charge for the bad jokes. Those are on the house. And now, before I loose you, allow me to end this rendezvous with a question so that we have something more to our relation if we get the wheels turning. Who would win - the Dead or the Zeppelin?

Senior .NET developer with 25+ years of hands-on experience working on real production systems. I help companies stabilize, modernize, and extend desktop and legacy .NET applications, taking ownership of existing codebases and delivering clean, maintainable solutions that work reliably long-term. Most of my work involves improving existing Windows desktop applications rather than building throwaway prototypes. I regularly take over mature or poorly documented systems, identify structural and stability issues, and extend functionality without disrupting production workflows. Clients usually come to me when a system is business-critical and needs careful, senior-level handling. My core expertise is in Windows desktop development using C#, WPF, WinForms, and the .NET Framework. I also have extensive experience supporting and modernizing legacy systems built with VB.NET, VBA, C++, and Delphi, including Office automation, custom installers, file system integration, and data-processing tools. For modernization and supporting services, I work with .NET Core, ASP.NET, Razor Pages, and REST APIs, which allows me to evolve legacy desktop systems, build internal web tools, or deliver complete end-to-end solutions when needed. I follow proven architectural practices such as MVVM, layered design, version control with Git, and predictable deployment processes. I’ve completed 120+ projects and 37,000+ hours on Upwork, working primarily on long-term and technically demanding systems where reliability, clarity, and ownership matter more than quick fixes. If you’re looking for a dependable senior .NET developer who can take responsibility for an existing system or build a stable desktop application from scratch, I’d be happy to discuss your project.
