Freelance Data Analyst | Scientific Web Developer | Digital Nomad (SEA)

Profile Summary

I am a freelance data analyst and scientific web developer with an MSc in Applied Mathematics and over 7 years of experience in research, education, and technical projects. Currently building a location-independent career as a digital nomad based in Southeast Asia, I work remotely with global clients on scientific data analysis, algorithm development, and research-driven software tools. During my postgraduate studies, I developed and published a Python-based web application for simulating numerical solutions to differential equations. I also completed a 75-day Erasmus+ internship in Barcelona, where I worked on exploratory data analysis, scientific content, and visualization. I offer services in data analysis, scientific programming, academic tool development, and research consulting — combining analytical rigor with clear, practical output. Let’s collaborate on meaningful, results-oriented work — wherever we are in the world.
