Andrey N.

An experienced pythoneer and web developer

Thailand - Tests: 3 - Portfolio: 2

I'm a Russian expat currently staying in Thailand. Before I decided to move abroad and work as a freelancer, I used to be a programmer and CTO, so I have deep knowledge of both business needs and appropriate technical solutions. I also have a great understanding of low-level computer principles and codes; I have been writing some C++ and x86 assembler codes for a few years. I've been coding since I was 14. As a student, I took part in an IT competition and won 3rd place in my city. Most of these competitions strongly relies on algorithms and mathematics, so I do have knowledge of programming patterns and algorithms as well. I switched to Python as my main programming language more than 5 years ago. I found it simple, clean, reliable and powerful. Soon after that, I noticed Django and started using it when it was an early pre-release version. Whether you need a complex, corporate-level solution such as a social network, or just a small script performing a simple task - I will do it quick and efficient. How a good IT solution should look like? It must be: - reliable: I always test my code; - solid: I think through all the important details and features before typing any symbol of code; - complete: my solutions will satisfy your business needs for 100% and even more; - high-quality: forget about stupid or unclear code - I follow all the theoretical and practical principles of writing code (including standards such as PEP8). The list of technologies and programs I worked with: ★ Python, Django, Flask, many external Python libraries ★ CSS, HTML, Java Script (including libraries such as jQuery) ★ MySQL, PostgreSQL, MongoDB, SQLite ★ Lighttpd, Nginx, Apache, Cherokee, Tornado ★ High-load optimization (including creating the appropriate project architecture, database design, code refactoring, choosing right tools etc.) ★ Selenium ★ Git, Mercurial;,, ★ Many data formats and files, such as binary, graphic, audio, plain-text, CSV, XML, OpenOffice and MS Word formats ★ Mac OS, Linux (including console and server administration), Windows, iOS, Android ★ PyCharm, Sublime Text, Text Mate, nano, vim; intermediate Photoshop skills

Tomislav Rupcic

Python/Web developer/Data Mining

Croatia - Tests: 6 - Portfolio: 1

I started programming computers when I was ten years old, and, over the last 18 years, I've realized that I am, well, a programmer. That said, I do have the "people skills" necessary to remain competitive in the world of programming. When needed, I'm a "sit in the corner and program til the wee hours of the morning geek"... otherwise, I'm just a "fun to talk to, easy to get along with normal person". I have always enjoyed the challenge of creating interactive software. With the birth of the modern Internet, I found a new love in web development and web programming and data mining. I face every new piece of code as a fresh new beginning... a chance to do it even better, while, still using "what works" from the past. My objective, here at oDesk, it to provide potential employers with my expertise in the field of website development, and programming.
