Open to Opportunities

Calin Gabriel

I build distributed systems that handle real complexity — payments, energy, e-commerce — for companies like Scout24, RWE, and NETS.

From Galati at 16 to DAX-listed enterprises. 6+ years of shipping scalable backends, test-driven, across Europe.

The Story Behind the Code

Where I started

From Galati at 16 to enterprise systems

At 16 I won an internship contest competing against college students in Galati. That firm hired me, and I learned Linux and web development hands-on before most people pick a major. I then moved to Cluj-Napoca for a Computer Science degree at Babes-Bolyai University — building the formal foundation under the practical instincts I already had.

Where I am now

Fixing hard problems at scale

After graduating I worked with progressively larger companies — culminating with DAX-listed enterprises like RWE and Scout24, and major EU and US players. I'm a generalist by pedigree but a specialist where it counts: performant, scalable distributed systems. I iterate with tests, automate relentlessly, and use AI tooling to accelerate workflows — not to replace thinking, but to spend more time on the problems that actually matter. Currently focused on payment services, with strong experience across energy and e-commerce.

Where I'm heading

Building what matters, with teams that think

I want to keep refining distributed systems that handle real complexity — not just traffic, but domain complexity. I'm looking for inspiring, smart engineering teams across Europe where high standards are the baseline and the problems are worth solving.
