Systems & Software Architect · Aviation & Defense Systems · Mobile, Web & Cloud

Systems and Software Architect with 20+ years of experience building mission-critical real-time simulation, high performance software, and high fidelity avionics software.

Driven by relentless curiosity and an obsession with how complex things work under the hood. Whether it's dissecting flight dynamics, writing low-level code, or building hardware with my own hands, I thrive on hard problems, unfamiliar territory, and the challenge of making things run faster and better than expected.

My engineering philosophy is simple: don’t fear mistakes, just make sure to make better mistakes next time. Roadblocks are inevitable, but I live by the reality that:

for every complex problem there is a solution that is simple, fast and wrong.

Early Explorations & Undocumented Archives

DOS · Windows 3.1 · OS/2 Warp · Windows 95 · Early Explorations
Pre-2008

A significant portion of my early engineering journey remains undocumented or lost to time. Starting from the MS-DOS era, Windows 3.1, OS/2, and Windows 95, I built countless utilities, simple games, and creative weekend experiments that have since vanished with legacy magnetic media and aging hard drives. While the vast majority of these programs were authored in C and C++, I also programmed extensively in Pascal, developed commercial business software using Borland Delphi and C++Builder, crafted Java applications for university demonstrations, built numerous web projects in JavaScript, and tinkered with hardware interfaces and x86/x64 assembly. Alongside these were several custom 3D game engines that were never finished—each serving as an invaluable sandbox where I honed my understanding of low-level systems, mathematical modeling, and deterministic real-time execution from first principles.
