Hey — I’m Kristofer Soler, a Backend Engineer based in Oviedo, Spain with nearly 8 years of professional experience building web applications that are fast, reliable, and secure.
I work at the intersection of backend engineering, cybersecurity, and infrastructure. I’m drawn to hard problems — the kind that require understanding a system deeply before touching it.
This blog is where I share notes, write-ups, and thoughts. No corporate fluff.
