Summary

For more than 12 years I’ve been working mainly as Backend Engineer in different projects. The majority of projects were based on Java & Spring. My last experiences have been focused as Software Architect and I figured out is the most I like. I love solving complex problems, looking for the best solution possible, improving the performance of an application, designing a solution using best tools and other topics related to architecture stuffs.

I believe that collaborative work is the only way to have best result. I like to help to my workmates, contribute based on my experience and learn from them.

In spare time I’m interesting in Crossfit and cycling with my mountain bike. Also I like to play with personal projects with Arduino, IoT, Raspi, RPA. More in my personal site frandorado.github.io
