I'm a long time programmer who have worked on many languages and technologies. I come from the fun early ages of the first 8-bit personal computers when I learned how to deliver using wisely the resources. I started with BASIC and Assembly language and along the time I accumulated a cool crazy portfolio of technologies.
Although the technology was the fun stuff I am also fascinated by using the best approach for each problem, so knowing the proper techniques and engineering tools. I take techniques seriously and love clean, organized code, easy to read and maintain. Of course, there are times it pays off to be pragmatic and just deliver, coming back later to fix the mess.
So, that's it, I'm a programmer, who loves programming and software engineering.
I have several successful projects developed with C, C++, C#, Java and Perl so those are technologies I consider myself an expert. Beyond languages I also have expertise on SQL (design and programming mainly using Oracle and PostgreSQL), UNIX (administration, shell and system programming), Windows (application and system programming), API development (from low level up to RESTful/HATEOAS ones).
("Focuses"? Yeah... I have this problem with focus: I want to learn everything)
There are some really old technologies I am good with I wouldn't mind having to deal with them again:
