Hire the Best Mathematica Specialists
in Venezuela

I'm a text translator and editor, I am a Spanish native speaker and I am fluent in both English and French (I study these languages in an institute and lived abroad) I have ten years of experience with the English language (Translating and teaching) This enables me to do both edition and translation projects satisfactorily and five as a French speaker. I've completed many projects over the last five years in text translation and edition in an independent way and all my clients have ended up satisfied with the outcome. Quick note: I study both Physics and Philosophy, the study of these particular subjects allows me to do projects in both areas with sufficient precision and knowledge. _______________________________________________________________________ Thanks to my career I have advanced level skills in Latex, more than 7 years, a time where I developed strong knowledge about it. My experience covers: • Word, PDF, Excell, handwritten to Latex. • Beamer. • Tikz. • Geogebra, WolfFram. • Overleaf. • MathJax. Furthermore, I have a high level in Word, Excel, and PowerPoint. I can code .tex to use it in WordPress, HTML, and other platforms with a mathematical environment. Now I'm working as a teacher assistant in the Physics school at Carabobo's University which is known as one of the top universities in Venezuela.

Hello! . I am Hernando, an Applied Mathematician, Data Analyst, and Full Stack Developer. With 26 years of experience as a university professor of mathematics (specializing in algebra, calculus, and applied statistics at the Universidad del Zulia) and as the founder of the consulting brand Guzmathic, I bridge the gap between deep academic rigor and practical, scalable business solutions. Beyond coding, my core strength lies in algorithmic thinking. As a Venezuelan National Chess Master, I bring a high level of strategic planning, logical optimization, and foresight to every dataset I analyze and every architecture I design. I don't just write scripts; I build robust mathematical models tailored to your specific technical or financial needs. My core technical stack and expertise include: Programming & Full Stack: Python, JavaScript, MATLAB, R. Data & Analytics: Advanced Excel (VBA, macros, dynamic dashboards), SQL Databases, Statistical Inference, and Predictive Modeling. Mathematical Modeling: Optimization algorithms, Bayesian conditional probability, linear/multiple regression, and numerical approximations. Academic & Technical Writing: LaTeX, Overleaf, and the creation of highly technical documentation or competitive syllabi. Recent real-world applications of my work include: Designing and deploying quantitative portfolio backtesting tools in Python using historical corporate fair value data and Sharpe ratios. Building complex, multi-factor Anti-Money Laundering (AML) risk matrices in Microsoft Excel for the financial sector. Developing and structuring advanced algorithmic problem sets for international mathematical Olympiads. Whether you need a full-stack data pipeline, a complex statistical model translated into efficient code, or a flawlessly typeset LaTeX manuscript, I deliver precise and mathematically sound results. Please feel free to review my GitHub portfolio to see my algorithms in action. I look forward to bringing decades of analytical expertise to your next project.

The main research and teaching areas in which I have been working for more than 20 years are: Calculus, Numerical Analysis, Partial and Ordinary Differential Equations, Numerical Solution of Differential Equations, Fluid Flow Simulation Models, Discrete mathematics, Topology. In addition to programming language: Matlab, excel, C, C++, Verilog.

I am a native Spanish-speaking with a Doctoral Title in Theoretical Physics. I have more than 30 years of experience in teaching Physics, at the undergraduate and postgraduate levels, and as a scientific researcher. Since I work in theoretical Physics, I have an excellent background in mathematics. I am fluent in English (Bilingual) since I use it frequently as the common language in the scientific media. Is common in Physics to use the LaTeX editor, for writing research papers and academic documents, so I have vast experience editing texts in LaTeX, and making diagrams with Tikz. As a researcher in the field with many published research articles, and also a referee of scientific journals I have experience in editing and proofreading, technical, academic, and research writings, in Physics and other scientific or technical areas. I can ensure that any document I review or produce is done accurately, quickly, and efficiently. Any project you propose in the above areas of expertise will be managed with high-quality standards.

I am a mathematics teacher. I am trained as a researcher too. I can do jobs like writing and correcting math books, correcting books and other writings for publication, correcting theses at different levels, and suggesting improvements. However, I can help with many other tasks. I offer live online tutoring sessions via Upwork Video Chat for university-level mathematics, including Probability and Statistics, Calculus, Linear Algebra, and Differential Equations. With over 25 years of teaching experience and a Ph.D., I provide real-time support, problem-solving guidance, and LaTeX document preparation. My services can be listed as follows: 1.- Mathematics I can be a tutor for the following courses: - Calculation in one and several variables - Discrete Mathematics - Ordinary differential equations - Real Analysis - Linear algebra - Numerical analysis - Biomathematics - Probability and statistics Investigation of mathematical models described by means of systems of ordinary differential equations. Research on statistical data analysis. 2.- Mathematics Education I am also investigating mathematical didactics in the subject of Anthropological Didactic Theory. 3.- Translations - English Spanish - Italian Spanish - English Italian My skills and qualities for which to select me to do a job are, among others: I have a Ph.D. from the Central University of Venezuela. My academic profile may be seen on Google Scholar. I have been a university mathematics professor for more than 25 years. I am currently retired and have time to dedicate myself completely to potential clients. Management of Office and Google software. Management of MATLAB software. I have significant experience with the LATEX environment for writing scientific articles. I can provide services in Spanish, Italian, and English.
