ABOUT ME
Java, PHP, Scala developer
Java, PHP, Scala developer
I have been a Software developer for two decades now. While in touch with the latest frameworks, I always put emphasis on fundamental concepts and best practices in code writing first. I strive to write maintainable code and follow a strict separation of concerns. Duplicate or dead code is not an option. I follow a client-oriented approach, understanding that the client's success is my own success.

I have been developing various Java back-end solutions since 2004. I have strong experience with profiling and performance of JVM. I have been working on plain vanilla Java projects, back in days of Java4 and Ant and I have been in non stop contact with Java during arrival of generics, Maven, Spring and streams.
I have worked on huge and complex projects, containing 10000+ classes. I can confidently handle such complexity by utilizing correct modularization, separation of concerns and following DRY principle.
Influenced by Scala, since 2006, I have been promoting functional programming style in Java too. This allows me to fully utilize Java compiler, avoid unnecessary errors and enable constant refactorings.
I have strong experience in batch data processing and reporting systems.

I have worked on and off with all major databases. With MySQL however, I've had the most experience. I have also worked with Enterprise edition of MySQL, setting up clusters, data replication and data retention.
I have strong understaning of database transactions and I can effectivelly apply them in both of my major programming lanaguages, Java and PHP.
I also have strong experience with reporting applications and I understands importance of efficient table structures. This includes suitable data types, indexes, compression.

PHP was my first programming language, which I used in production environment back in 2004. I became a Java programmer instead, but a recent project lead me back to PHP.
I developed a complex online casino software. We successfully used PHP for an enterprise grade application and processed real money financial transactions in very large volumes.
My unique contribution was ability to apply all enterprise patterns from Java. This includes proper handling of database transactions and static analysis of PHP code.
I have production experience with Zend Framework, but I can quickly pick up any modern major PHP framework too.
