PHP

Native PHP speaker, being my first programming language I appreciate it's pitfalls and it's advantages.

Object Oriented thinking for structuring code, applying design patterns wherever is the case. Optimizing my code performance-wise (with time and memory complexity in mind), for readability and extensibility.

  • Inter-Application Entity Level Lock System (for when you want to edit the same thing in two different applications)
API Design

I have done a great deal of REST/ API's using:

  • security layers
  • memory optimized Object Oriented designs
  • incorporated validations in the API classes, both request structure and values
  • caching systems using either no-sql light databases (Redis, ElasticSearch, Apache SOLR) or HTTP cache like Varnish
Machine Learning / Statistic Predictions

As a personal project I'm using classification and regression algorithms for predictions and machine learning using the Octave/Matlab environments or in Python/Scipy libraries.
