SUMMARY OF QUALIFICATIONS

I am a versatile software developer with ten years of commercial experience. Starting from the most recent, I have worked in the smart home industry developing web, desktop and backend applications. Further in the past I have acquired expertise in the niche of diagnostic systems, in particular within the marine and mining industry, implementing extensive multithreaded client-server systems and dashboard applications. Earlier, for a number of years, I was working in the oil and gas industry mainly for a field data analytics software provider, building desktop applications. I received valuable exposure to computer aided modelling (CAM) while specializing in the building information modelling (BIM) software sector and to geographic information systems (GIS) while working for a geodesy company. As an individual I am a keen problem-solver, with an eagerness to learn more and to stand out. Mastered skills starting from writing secure quality code, documenting and reviewing requirements, end-to-end testing, support and winding-up with interviewing candidates.

I continuously developed software installed on ferries, oil tankers and offshore platforms in order to accumulate and process equipment readings. This real-time software has been present on the market since 2005 and from the beginning has been built on the .NET platform. My job was to make sure our software is fast, stable and secure in terms of communication. I was also responsible for maintaining and implementing connection to the Azure cloud. For most of the time in the company I was delivering a dashboard UI for ship operators that monitors all the devices, heavily using WPF.

My daily work focused on achieving goals in two-week sprints with the help of Team Foundation Server. As part of a Scrum process, I act as a deputy of the Scrum Master by leading sprint review and planning. I am responsible for interviews and candidate selection. I oversaw a shipping of a product worth tens of millions of Euros delivered with the gate-model not only by performing code reviews but also executing user acceptance tests and managing a testing team in India. I stick to techniques to deliver quality software based on various automated tests ranging from unit tests to automated tests in virtual machines (which runs inside an engine of my idea) triggered by every code check-in.
