I tinker with infrastructure and development from the kernel to the browser, having spend past couple years trying to run towards the lower levels of the stack. I've worked across multiple different industries. Most of my professional time I spent across media and financial landscapes.
I largely credit Ansible with pushing me towards the more interesting problems - I discovered it 9 years ago, as a first year high school student trying to troublemake across all computers in the Linux classroom.
I was 16 at the time and it has been the "gateway drug" for anything from Linux itself, C++ and other learning choices. I could say it has saved me from a lifetime of JavaScript!
Last year, I've gotten a chance to work alongside Juno Innovations as a consultant and architect their deployment workflow - of course powered by Ansible. The bootstrapping approach is rather novel, so I thought it'd be great to share it with the community at large.

My interests have varied over the years, but tech has always been a constant. During my electrical engineering studies, I initially gravitated toward electronics. However, along the way, I discovered the joy of programming and have been immersed in it ever since.
Currently, I am interested in Nix, virtual reality, and open-source software and hardware. I’m always eager to learn new and interesting programming languages, tools, frameworks, and architectures, such as RISC-V. The only thing that limits me in this pursuit is time.
