• English became my daily work language.

About the company

Emarsys is a world leading provider in email marketing. Ebay chose us as we are capable of sending 50 million emails in an hour to its registered users. The company brought its development to Hungary, paying the highest attention to proper quality software development methodologies.

Experience and goals achieved

• I earned a lot of experience about Agile methodologies.
• We worked in XP (eXtreme Programming), full time TDD (test driven development), and pair programming.
• I’ve learnt a lot about continuous integration, frequent builds, working in SCRUM, planning stories, dividing them to 1-2 hour task cards, estimating required task times.
• We created a modern graphical interface to set up highly customizable email marketing campaigns with a lot of filter options, timings, reactions to the user reactions, where the client could drag and drop the various events and plan the whole life cycle of the users.
• We had to develop in a legacy environment with full time TDD, testing everything necessary that we touch, making it sure that when our clients press the red button, 50 million emails don’t go out to their clients with corrupt data or bad format.
• I made and demonstrated an alternative way of handling client/user data with MongoDB instead SQL, reducing server load, reducing development time and complexity.

Technologies used

PHP, MySQL, Yii framework, MxGraph, Linux (Debian and Ubuntu), Phing, Sinon.js (unit test framework), JUTE (Javascript Unit Test Environment), js-test-driver, jQuery, Xdebug, eXtreme Programming, SCRUM, Agile, TDD, pair programming.

About the company

Sanoma is a multinational company present in 17 countries in Europe. In Budapest, it employs 700 people and has contracts with a lot of suppliers.

Experience and goals achieved

• As my most exciting role, I was the Lead developer on the PPCS (Product Price Comparison System) project for the Sanoma companies (across Europe), developing olcsobbat.hu and kirakat.hu.
• I coordinated two internal developers and two external development companies.
• I gained more experience with PHP, Yii framework, Git, MongoDB (noSQL database), Redis, MySQL, Node.js, nginx, Graylog, Gearman, Membase, Memcache, apache, Linux.
• I worked close together with an editorial staff. I was in a daily touch with 20 people collecting ideas and making them happen. I enjoyed this role pretty much.
• In my dev team I forced bug tracker usage (ActiveCollab), IDE for everyone (PHPStorm), enhanced processes, introduced a Kanban board, new code review rules, new deployment rules.
• I started to hold retrospective meetings and made continuous optimizations in the development and deployment process.
• I introduced unit testing using PHPUnit and automated acceptance testing using Selenium and Jenkins. Many problems/bugs were solved quickly by putting effort into these tools after hunting the bugs for a month or even more in the old system. Our deployments became much safer.
• I optimized a lot on the old site before the engine switch using Xhprof, Xdebug, query log, slow query log, munin, jetprofiler, mysql explain, sphinx, memcache, and a lot of refactoring. On my first work day I got the site in a state where it was simply showing a blank white page sometimes during daytime, not even at the peak load, and I could successfully get it ready to handle the highest Christmas shopping traffic and ad campaigns.
• I worked close together with the Sanoma system administrators to get experienced with the latest technologies.

About the company

EPAM is one of the largest multinational outsource companies employing 600 people in Hungary. We were delivering updates for the Venere project, which is the largest online room reservation system in Europe (www.venere.com).

Experience and goals achieved

• I had to analyze and understand the business process of the onboarding (with no documentation from the previously dismissed development team), registration and activation of a hotel and its rooms, and refactor it to satisfy the needs of the new owner of Venere (Expedia) by introducing internationalization, localization and templating into the communication process with the customers.
• I also had to work on the rewrite of the room type handling system, which included user interfaces (optimised the user experience via replacing the backend validation on the client side and creating a richer user experience using JavaScript, generating dynamic page elements and forms in real time) while keeping the compatibility with the existing database structure.

Technologies used

Experience and goals achieved

• After 3 months I made proposals for enhancing the work processes of the company, many of them were brought to live.
• After 6 months I got my own project to start from scratch using any technology that I find useful.
• After 9 months they were completely satisfied with my work and I got promoted with a 75% salary raise. At that time I already had offers from large development companies to be a lead developer at them. I wanted to stay as I loved my work, it was my hobby and my life.
• I gained insight into JAVA/J2ME and NFC technologies (mobile applications), my company sent me to a personalized NFC technology inspection to the Software Park at Linz/Hagenberg.
• In the main product of the company I have introduced AJAX based ideas and have done several significant performance optimizations (like optimising the parsing and building of 50 MB XML files, and reduced the number of database queries, making memory consumption from 500 MB to almost 0).
• My own project replaced legacy extraordinary event / accident listing services at Hungarian Railways. It had 4000 simultaneously logged in users. I designed the whole architecture of the system. The goal was to enable users to add new events happening on the railway without creating duplicated reports and allowing users to view the version history of an event. The system featured a powerful search engine and extensive reporting capabilities utilised by the government.
• I participated in the migration from MSSQL to Oracle.

Experience and goals achieved

• During my studies in 2007 I was asked to give lessons of Computer Laboratory 5 to groups of third year Software Engineering university students about Oracle, SQL, XSQL, XML, XSLT, JDBC and PHP.

Since 2003 I have been developing my own blog engine as a hobby, which provides me continous positive feedbacks. This allows me to experiment with cutting edge technologies and to try out upcoming ideas.

In 2000 I assisted the founding of HWSW (the largest Hungarian IT related portal), while running a column of index.hu by the request of András Nyírő (founder of index.hu, the most visited Hungarian online magazine).

In 1998-2002 I was the head and programmer of the online news paper called Internews. I was leading a group of 20 authors who were publishing on the site as a hobby. I managed to get the latest hardware from IT distributors for my staff to test it and write reviews about them. Our staff was invited to the European introduction of Intel Pentium 4, Microsoft Windows 2000 launch, and many other bigger events. Many partners realized how young I am only when they met me in person.

In 1997 I put my homepage online, which was has been even mirrored for offline reading in a magazine called CD-MAX, to show offline users what they could found nowadays on the internet. It was the recommended site of the week on Hungary’s largest online magazines (Internetto and Index.hu)
