About Me

University Graduation
My journey began over a decade ago when I entered university, immediately gravitating towards the realm of theoretical computer science (TCS). During those formative years, I was involved with a graphical Petri-Nets engine for modelling concurrent applications. This foundational experience set the stage for my academic endeavors.
Venturing into the depths of algorithm design and concurrency, I found my passion for languages like Go. In September 2015, I played a pivotal role in bringing to life a Kubernetes-based micro-service deployment, right after K8s came out of Public Beta.
Concurrency
Security
My fascination extended to communication security and system stability, stemming from my roots in distributed systems. With a focus on Blue Teaming and Site Reliability Engineering (SRE), I've spent roughly five years delving into the realms of Cyber Defense.
Yet, my true calling lies at the intersection of security analysis and systems design. Today, I specialize in holistic cloud architecture and reviews, boasting proficiency with many public cloud environments. Armed with extensive coding experience across a spectrum of modern languages, I embody a unique blend of engineer and architect.
