    Senior Programmer & Numerical Modeller

    Spain - Last active: 12 days ago - Tests: 4

    My name is Alvaro (nickname: varocarbas) and I am a senior programmer (+7 years), who has participated in a wide variety of projects involving custom software development and numerical modelling. I have recently reopened my 1-person company: Custom Solvers 2.0. My favourite programming languages are: - Desktop-based: C# & VB.NET (mainly Winforms); VBA (MS Office Macros) & VB6; Java and other C-based languages; FORTRAN. - Web-based: PHP & JavaScript; ASP.NET (C# & VB.NET). Customsolvers.com 2.0 references: - About me (varocarbas): http://customsolvers.com/en/pages/varocarbas_com/local/about/. - About Custom Solvers 2.0: http://customsolvers.com/en/pages/company/basic_information/. - Principles: http://customsolvers.com/en/pages/company/principles/. Mainly interested in fixed-price projects over $1000. NOTE: this was one of the freelancer-network profiles (although not precisely the most important one) which was associated with the previous version of my 1-person company (trendingIT/Custom Solvers). In 2015, I tried to create a new profile for Custom Solvers 2.0, but UpWork didn't allow me to do so (even though I proposed them different alternatives, logically by avoiding the deletion of this old account. And I certainly don't like unreasonable inflexibility...). In summary: Custom Solvers 2.0 will also be using this profile.

    E-learning perfectly combines my artistic/ creative design talent with my passion for training, development, and education. Having worked with both Instructor Led Training and Computer Based Training in my past management experiences, it is a pleasure to be on the development/ design end of production.

I consider myself fortunate to have continued to develop both areas of my passion: working with people and the arts. I have spent over 10 years in staff development, building effective and efficient teams through my roles in management. While putting a special focus on driving individual strengths and positive working environments. My experience has led me to a proficient understanding of sales, customer service, revenue management, staff development, and creative thinking.
