Worked for 10 years in a developer and then software architect role, building high-performance mission critical systems for the largest telecommunications company in Romania.
Java has been the main trade, but have gone through C++ / Python / Perl / PHP projects along the way, and have built a couple of domain-specific languages to facilitate customizable solutions.
The startup I developed (http://umbrella4jane.com) got me the experience I needed in the Web world, and I currently have very good client-side experience with Javascript (JQuery, Ember.js), HTML, CSS.
Java stack: Java, Spring, Spring MVC, JSP, Thymeleaf, Spring Boot, JPA, JNI Interfaces (C -> Java, Java -> C), JUnit, Mockito Ruby on Rails stack (beginner / intermediate)
Web Client Side: Javascript, CoffeeScript, JQuery, underscore.js, Ember.JS, HTML, CSS Databases: Oracle (5 years), Mysql (3 years), SQL Server (less than 1 year)
Other languages: Python (intermediate), C++ (intermediate+), Clojure (exploring as a hobby) Other skills: DSLs, Multithreading (Java, C POSIX), high-availability systems, Unix system administration, a bit of shell scripting IDEs: IDEA Intellij, PyCharm, RubyMine, Emacs (-)

Umbrella 4 Jane January 2013 - October 2014 As founder and sole developer, I designed and developed the platform - website, back-end processes and got the infrastructure up-and-running. Got a lot of experience in client-side development during this process (a previously shady area for me), finally ending up with a stack based on Ember.js / JQuery on the browser, with a Spring MVC / Hibernate-JPA back-end;
MySQL as the database server of choice; Redis for back-end messaging to pass asynchronous jobs. Gained experience with setting up server-side Linux services / back-up facilities / etc.
