    Full-stack engineer / Python Developer

    Lithuania - Tests: 4 - Portfolio: 3

    Previously: Dell inc. as Senior Software Engineer, Barclays as Senior Cloud/Unix Engineer. Disclaimer: oDesk is not perfect. Sometimes you've got a client with low response rate, when project goes for months, and in the end, client appears to be doesn't know difference between backend and front-end and API terms.. And we ended up with a work which client didn't intended me to do. He didn't check my results even once during 1 month period! I'm trying my best, but sometimes there's conflicts between which technology to use, while I've been hired to code with flask framework, client requested to use other framework which I've been not familiar with. It's no problem to learn it but, I'm not into legacy stuff so I've refused to processed, at least because, as always, I'd be the one to blame, when their proposed solution, would fail their expectations. This would end up in blames regarding my competence in my field, although the solution was not meeting our use-case :) Please choose technology responsibly, and only if you're an expert in that field, and not because "you've heard it somewhere" :) If you're a client who wants a time saver in your team, a guy who knows his field as best as he can, a person who will bring you valuable solutions, I'm the one to go with. But all above works only when you trust me and you'll communicate with me constantly. Specialties: High Availability Systems, Clustering Environments, Cloud Computing, Unix environment Primary Skills: Development, Scalability, Deployment in other words SOA and REST is everything in IT. 3 Years python/django developer with 7 years of PHP background. 10 Years of Linux administration. 1 Year of Openstack development, deployment Some technologies which I've been using recently a lot: ansible, chef, saltstack, mongodb, cassandra, redis, rabbitmq, celery, node.js, angular.js, ceph, nginx, gunicorn, zeromq, sensu, logstash
