Petr B.

Senior Developer, Consultant

Russia - Tests: 5 - Portfolio: 2

I have strong background in UNIX/Linux software development, Master's Degree in Computer Science. I worked on Enterprise high-load distributed hosting automation systems as a Team Leader (3.5 years in SWsoft, Inc., now called Parallels). For the last 6 years I'm running my own small software development business in Russia with primary focus on Python/Django apps. Not pure Web but often involving integration with hardware (Proximity Cards, Sensor Screens) or external systems like Payment Processing, SMS Gateways, GABRIEL (Airline Reservation System), etc. I can take an idea and turn it into a working business, through all the intermediate stages. Also I have experience of investing my own funds in my projects, so I feel the difference between "perfect code" in a month and "good enough" code that increases the revenue right now. Nevertheless, my code is very good: no copy-paste, always written with performance, flexibility and security in mind, etc. On oDesk I'm looking for (and actually find :) interesting projects with a sight on long-term fruitful cooperation. I'm also open to smaller activities (e.g., consulting) where my knowledge can be helpful.

Rails dev - Linux admin

Argentina - Tests: 19

Over the past 20 years I have been involved in several large projects including both software and hardware elements. I am looking to bring my expertise to businesses that have complex needs but don't have the volume to justify the expense of in-house talent. My skills include: - Project and team management: I have led web development projects from 3 to 30 people, using RUP, Scrum and homegrown methodologies. I know how to earn trust and gain the respect of collaborators, management, peers and clients. - Rails - I love the platform and have been working almost exclusively in RoR projects in the past 4 years for several different clients. - I prefer to use Thin, nginx, haml, jQuery, Semantic UI, Webistrano, MySQL or SQL Server, RVM and Rails 4.0 for new RoR projects. - I have experience consuming services like Twilio, SendGrid, UrbanAirship, and interfacing with payment gateways (usually Stripe and PayPal). - TCP/IP networking in general and the most popular protocols: HTTP/HTTPS, SMTP, POP3, SNMP, SSH. I also have a lot of experience troubleshooting connectivity and performance problems. I enjoy working with peers, but I can also work alone as developer and server administrator in small projects.
