Web Development and Data Science

[Web development] My expertise is in developing custom dashboards, applications, components, and data visualizations (including GIS-based visualization). I am an expert at building custom visualizations using D3. I also have experience with many other JavaScript visualization packages such as Mapbox, Chart, Highchart, or Leaflet. I love designing custom applications and components that solve complex problems or automatize intricate processes. Whether you need a custom environment to manage your data, optimize an industrial process, or automatize a repetitive IT task, I have practical, robust, flexible, and scalable solutions for you. I routinely integrate data visualization into pre-existing applications relying on a variety of web frameworks. I have particular expertise creating and integrating components into React applications. I also have experience with Django and the Phoenix Framework. [Data Science] I specialize in data collection, cleaning, visualization, and analysis. I am an expert R and Shiny user and I also work extensively with Python. I have experience in Statistical Analysis, Machine Learning, and Optimization. I’ve taught Probability, Statistics, Machine Learning, as well as Data analysis and visualization in several top U.S. Colleges. Count on me to deliver industry-grade products while adjusting to my audience and understanding the needs of users with varied levels of Data Literacy.

Testimonials

Endorsements from past clients

"Martin worked with us to automate data reports for our clients' deliverables. He was phenomenal to work with. From communication to understanding the goals of the project to exceeding what we had envisioned, Martin saved my team weeks of work. He not only managed the goals of the project and kept me informed of progress but also implemented an incredibly strong QC process to ensure the final product was exactly what we needed. The reports he automated contained data from a national survey with over 100 questions. It was a complex job. I highly recommend working with Martin and hope we can partner with him again on future projects."
