    Alex S.

    Programmer / Developer

    Russia - Tests: 9

    I'm awful at selling myself, it gave me a headache just to write this text. Someone called me a superstar, when I passed the screening process for a Python developer position, to this day I still laugh about it. No, I'm not bad by any means, I'm probably better than average, but I'm certainly not Guido or Armin Rigo. My skills and experiences, I have a wide range of those, from your typical web development to computer vision and genetic algorithms in context of game development, but most of it is on the jack of all trades level, definitely not an expert. I suppose my forte is Python backend development, but I've done frontend work as well (AngularJS). I'm currently trying to get into MEAN stack, since it seems to be popular nowadays. As for workflow and methodologies, I double check my commits and try to write the code as clean as possible, I follow TDD when possible, and prefer an uncluttered text editor and terminal tools as my IDE.

    web development / net presence

    Australia - Tests: 2 - Portfolio: 4

    After graduating in computing, I spent a year developing interfaces and APIs for financial transaction devices in Windows before moving into an area that had more appeal for me : system level communications and messaging, largely focused on a C++ / Unix / Oracle platform. I spent six years mostly juggling messages and communication channels between databases and queues. But I got tired of living in big cities, and hatched an escape plan. I started doing short term contracts for web projects using a range of scripting languages at the server, and AJAX in the browserI began with various short term contracts for web interface development using content management systems and frameworks including Drupal, Django and Node, programming in languages including PHP, Python and Javascript/Coffeescript. I've moved on to building web apps with rich client side frameworks, often with a full javascript stack including mongodb.

    Hungary - Tests: 6 - Portfolio: 9

    I have been developing applications for 4 years in C#, ASP.NET MVC, Android, Java and C/C++. During this time I managed to get skills to write robust and optimal code in these languages and frameworks. I have a deep knowledge in networking concepts, protocols, VoIP technology and different database systems. I have worked with different Linux/UNIX systems and Windows so far. I used design patterns several times in practice, used TDD principles, set up continous integration and builder systems for larger projects. Why hire me: work efficiently, deliver on time, write maintainable code, provide good code analysis, learn new things fast.

I have a good experience in the development of multithread client-server applications, windows services, dll-s and cross-platform libraries. One of the specific features of my job was writing readable and easy-portable C-code covered with tests.Another interesting feature is working in small groups dealing with frequently changing goals. The major benefit of this style of work is a great experience on all levels of software development process (from project design and requirement development to final tests). Besides, I have a great interest in the research of new technologies and IT science related fields.

    +5 years exp in hosting industry; NIX/WIN servers config/tuning

    Ukraine - Tests: 10 - Portfolio: 1

    During the last 5 years I have been working in a company that provides a full range of hosting tech support. What does this mean? - quick and complete resolution of your problem. Why quick? - because a customer wants their site to be up and running 99.9% of the time. Why complete? - because if the issue is half-fixed now it may arise in the future and the customer will have to move to another provider who can solve the problem (you know hosting is a highly-competitive marketplace). All these factors are forcing me to have (or gain as fast as possible) a wide range of knowledge in system administration, programming, code debugging and customer relationship.
