Álvaro in wenigen Worten

I'm a technical consultant (Technikerberater) and Backend developer, dealing with different programm languajes like Java (including spring framework), Javascript, Node.js... in the daily basis.

I have more than 10 years experience working as IT technical guy (developer, level 3 support, consultant, etc.). In my last project (for almost the last 4 years) I was in the Technical Experts team, which gave support to several other teams in the technical topics like: development of some applications/tools, analyzing problem and solving them, defining APIs, implementing some of them (mainly the ones close to the security topics), ethical hacking support and vulnerabilities analysis, helping in the integration of the different pieces in a cloud environment, etc. I've worked also as technical architecture.

My strongest characteristic is not what I know currently but what I'm able to deal with. I'm not afraid of learning new things, tools, platforms, etc. and I do in short time. I'm also good analyzing problems, not stopping just in the current error itself but trying to find the root of it. Due to those characteristics I've been usually a cross actor in projects, acting as developer, integrator, issue analyst, security adviser and developer security pieces, technical support, etc.

Since I don't speak German fluently, I'd rather prefer to work in projects in English.
I could work onsite (Frankfurt and nearby) or on remote with punctual travels if needed.
