LANGUAGES
English Upper-Intermediate
Spanish Native
A programmer with somewhat shallow experience in a wide range of areas. Have been swopping technologies and roles a lot. Started learning deep learning full time about a year ago, by experimenting and implementing papers and variations. Have worked on a bunch of deep reinforcement learning algorithms, and some other deep learning applications such as stock market predictions, image classifications, and text completion.
I would like to help people understand ABAP and SAPUI5, as these technologies, although in great demand, present a major barrier to entry due to the expensive courses and expensive learning materials. Furthermore, I would like to be able to take part in interesting projects here in my free time in order to be able to consolidate and deepen my current knowledge.
8+ years of experience in software development and working with different Data Science teams to solve business problems. I have worked with multiple industry leaders and helped them to reach the desired goals of the organization. While in this process, I have mentored multiple candidates who dream to achieve more in their professional career. I get along well with everyone which helps me in my growth and continuous learning process.
