Hey there! I’m Juan Manuel, an Argentine physicist with a Ph.D. in Astronomy. I’ve spent much of my career in academic research, including postdoctoral work, and I genuinely enjoy tackling complex problems. - I specialize in R and its scientific ecosystem, particularly the tidyverse. - With more than 12 years working with academic documents in LaTeX, I’ve contributed to theses, research papers, and scientific publications. - I have extensive experience with Inkscape, including refining publication-quality scientific figures and conference posters, integrating LaTeX, and automating repetitive SVG workflows through scripting. - I’m skilled at optimizing scientific code, improving both execution time and memory usage through profiling and efficient algorithm design. - I believe that clear and consistent communication is key to delivering top-quality work—let’s keep the conversation going! - My combined expertise in R and Fortran allows me to develop robust, efficient solutions for applications ranging from statistical modeling to numerical simulations. -N8N: My combined experience in programming and editing allows me to build clear, efficient, and reliable automations. I create smart workflows using n8n, designed specifically to meet real business and project needs.
