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.
