My role of choice in a project is the primary surgeon if it is something considerably small and involves no rocket science, or I also can work as a surgeon assistant on something complicated where an architecting of a system involves specific uncommon knowledge; still, some more simple areas could be covered by any qualified programmer. I love learning from people who know more than I do and have skills I do not have or am not good at. I am comfortable both working in a team and doing tasks by myself. Usually, I do not need much supervision. In most cases, I can understand tasks in business terms and ask all necessary questions to complete technical design and implementation.
I am not comfortable managing people unless it is a tiny group of close colleagues who are pretty independent and responsible but occasionally need some pure technical consultations or help with resolving non-trivial issues.
I value the most honesty, open-minded attitude, commitment to agreements achieved and hanger to efficiency in my colleagues. My primary work style is being an innovator. I love resolving non-trivial issues and tasks demanding out-of-the-box thinking. I better like a startup-like project management style than an enterprise with complicated rules and restrictions. I am looking for remote positions only.
PS If you are ready to try me as a Golang programmer, I would be thrilled. I love the language and want to try it in commercial development, but I haven't had an opportunity yet. I am a quick learner, but I learn much faster by immersion than by reading books or taking courses.
2019-2021 C#, ASP .Net Core, Web API, Azure
– Developed code generator library emitting code of a couple of languages (including C#). Using an Objective-C parser (developed by a colleague) translated quite a big project from Objective-C to Oxygene (Pascal-based object-oriented language).
2013-2014. .Net, Oxygene
– Developed and implemented the most complicated area of data migration solution for a significant Western European Telco provider
2004-2007. Oracle, PL/SQL
– I do not want to work on an old project with a lot of legacy code unless I am allowed and encouraged to introduce new technologies and refactor old code ruthlessly but carefully
– I do not want to work in the gambling industry
– I do not want to be just another brick in the wall; it might be something small, but it must be valuable
– If you do not think you could ever trust me, please do not hire me
– Currently, I am based in Kyiv (Ukraine), and I do not want any relocation.
