My profile is forever under construction ....I'm a passionated for declarative languages during the past 30 years with experience in programming for AI. At the beginning, I falling in love with Prolog, as my first serious programming language that I learned by myself. During this period, I taught several CS courses in many universities in Brazil. Recently, I got involved with Constraint Programming (CP) developing experiments with declarative programming languages. Additionally, I experimented with many tools for CP, finding a perfect match with languages like PICAT, MINIZINC, HASKELL, etc. Others classical programminglanguages, such C, C++, Python, et all, I have some knowledge to become anexpert.During this year, I am preparing for my retirement from UDESC. I am so proud of my career during these 35 years working for many industries and universities. By the way, I am still felling with good energy to work with certain activities. Although I am almost 60, my health is fine, since I'm used to swim in many open water competitions (from 3000 up to 8000 meters).This way I am ready for new challenges in programming and research: combinatorial problems, declarative programming, programming in logic, constraint programming, and so much more!Any proposal in Brazil or abroad are wellcome, as well as a "home office" work issuitable for me in this moment. Finally, some jobs in these areas as freelancerare also wellcome.There is a bit timid blog in: https://claudiocesar.wordpress.com to contact me, et all.
