PROFILE I'm a passionate geek and an experienced full stack developer with more than 10 years of code craTing. I love neat soluUons for both high scale infrastructures, big fishes in the industry as well as small MVPs which has to be great, shiny and be ready for "yesterday". During last 5 years Ruby was my naUve language and Ruby on Rails was my best friend along with Git, Bootstrap, AngularJS and EmberJS fellows. During my adventure as a developer I also was a BOFH (*now known as DevOp, previously as SysAdmin) so I enjoy providing scalable soluUons for running the code I write. During my 10 years adventure I've learned how to effecUvely manage my Ume (it was not so obvious at the beginning aTer all) and that being agile is a key to both mine and yours happiness. ignacy.co https://github.com/ignacykasperowicz http://www.linkedin.com/in/ignacykasperowicz EDUCATION TRAININGS Masters degree in Control Engineering University of Technology – Gdańsk Graduated 2010 Ruby Master Path at Codeschool (including courses like: Rails for Zombies, Rails for Zombies 2, Ruby Bits, Ruby Bits 2, Rails 4 pamerns, TesUng with RSpec) - 2013 Report Card Codewars - 4 kyu http://www.codewars.com/users/usecide Construx – SoTware EsUmaUon in Depth May 2011 SQAM - Manage team of test engineers February/March 2011 VMware - vSphere 4.1: Install, Configure, Manage January 2011 SoluUon Technology - In-Depth Serial Amached SCSI (SAS2) 2010 Infotraining - Programming in Python 2010 SKILLS Programming Frameworks Libraries Paradigms Plaporms Tools Storage Cloud Management Languages EXPERIENCE Ruby, Python, C, Bash, TCL/Expect Ruby on Rails, Sinatra, Django, AngularJS, EmberJS Bootstrap, jQuery Test Driven Development, Agile development Linux (Ubuntu/Debian) Git, Emacs, Sublime, Vim Percona Xtradb, MySQL, MongoDB, Redis, Memcache, Varnish, Sphinx, GlusterFS, PostgreSQL AWS, Heroku, ShellyCloud Chef, Capistrano English - fluent Polish - naUve AIR Project - upwork.com - Full Stack Developer (June 2015 - July 2015) • Prepare an MVP for digital currencies management web applicaUon • Integrate external APIs in AngularJS applicaUon • Technologies: AngularJS, Bootstrap 3, Grunt, Yeoman getsafe.de / teon.co - RoR Full Stack Developer (October 2014 - July 2015) • Mentoring, teach junior developers • ApplicaUon architecture design • Code reviews • Technologies: Ruby on Rails, Rspec dinneria.pl - RoR Full Stack Developer (March 2015 - May 2015) • Extend applicaUon features for both frontend and backend • AdministraUon uUlity for admin users • Develop unit tests for both Rails and AngularJS • Refactoring • Technologies: Ruby on Rails, AngularJS, Gulp, Rspec • Services: MySQL, Codeship, Shellycloud highskillpro.com - RoR Full Stack Developer (July 2013 - unUl now) • Extend applicaUon features • Add unit tests • Refactoring • Technologies: Ruby on Rails, Rspec • Services: PostgreSQL, Shellycloud eOasia.com - RoR Full Stack Developer (February 2014 - March 2014) • RoR applicaUon maintenance, bug fixing • implement new features (discounts, frontend UI improvements) • Technologies: Ruby on Rails, Rspec • Services: PostgreSQL tripsta.net - DevOp / Sysadmin (May 2012 - December 2013) • Maintain applicaUon cluster consisUng of 45 servers • Design and implement applicaUon stack with Varnish, HAproxy, Nginx, Apache2, Gearman, Sphinx, Percona Cluster, MongoDB, memcache • Cluster monitoring with Munin, Nagios, Pager Duty • Services redundancy with failover • Automate cluster management using Chef • Write custom cookbooks/recipies/extensions for Chef • Technical support for developers • 24h on-call duty • Technologies: Chef, HAproxy, Varnish, Percona, Nginx, Apache2, Memcache Intel • • • • - FW soIware engineer (May 2011 – May 2012) Design and implement power limiUng firmware features for Intel chipsets Fix client and plaporm issues, customers support for Dell Bug tracking Technologies: Embedded programming, C Intel • • • • - ValidaKon Team Leader (April 2010 – May 2011) Lead and plan work for small validaUon team (5 team members) Create tesUng policy and schedule for Intel products Provide Intel SoTware RAID support in ESXi VMware OS Technologies: ESXi drivers, RAID, C Intel • • • • • • - ValidaKon Engineer Tests design and implementaUon for Intel SoTware RAID Create test framework for tests execuUon automaUon in Python Execute unit tests, regression tests, report results Contact with open source community (Red Hat) Design hardware test tools – detect LED colours/blinking frequency Technologies: TCL/Expect, Python, Bash, Perl, PCB design, Sprint Sp.
