Chemical Engineer, Scientist

Hello everyone my name is Luis Jiménez, I'm specialized in scientific computation, researching, development of software in science. I'm strong and highly trained in mathematics, numerical methods and probability & statistics. I could help you with coding tasks such as: * simulation of processes or some physical phenomena dynamics through differential equations (finite difference method, finite element method, etc) including stochastic systems. * statistical and sensitivity analysis of experiments or data in business in order to find the parameters of the system to obtain hidden insights. * advisory about computational chemistry, thermodynamics, fluid mechanics, heat and mass transfer, separation processes and control theory. * development of scientific software including financial or trading algorithms. * scientific writing. General topics: * mathematics, numerical analysis, probability and statistics. * chemical engineering & mechanical engineering. * data analysis, machine learning, neural networks, time series, econometrics. * finance, trading algorithms, portfolio theory. My Previous Experience: My job since very young after 2007 was practically replicate the papers that published other scientists in the area of chemical engineering and control theory in order to create my own models, the most popular jobs were develop correlations or equations of state for thermodynamic properties of fluids, improve databases of compounds, solve numerically differential equations for example develop a model of computational fluid dynamics of a geothermic reservoir with water with oxygen and carbon dioxide as diluted solutes with a heat source in some surfaces. After 2013 (up to 2022), I've participated in a large researching project about renewable energy for a venezuelan university in the field of thermodynamics where we simulated a Kalina Cycle System with our own tunned equation of state with a Helmholtz equation of state, the main objective was optimize or improve the energy utilization of the power system according Second Law of Thermodynamics. A software elaborated from scratch was necessary, that includes iterative calculations of vapor-liquid equilibrium, and several subroutines to solve the thermodynamic properties of a binary mixture and all equipment mass and energy balances. However, despite my efforts I never published a paper in a journal up to this moment, but I'm in continuous researching. In my free time since December 2017 up to January 2024, I love to work in my own financial models and trading algorithms, doing tasks such as researching, backtesting my own trading strategies and using statistics, probability, stochastic calculus to isolate signal from noise and reduce the risk as possible of a portfolio of assets, developing a trading algorithm. Software: Python (with all relevant libraries), VBA / Office, Matlab, R, Julia. Others: Javascript, SQL I can write documents in LaTeX.
