Hi, I’m Randy Karels.
I’m a data analyst and web developer
from Minneapolis.

Data Analysis & Information Design

I create clear, compelling reports and graphics that solve people’s problems. I love information design and finding the best combination of text, tables, charts, and maps that most effectively illuminate trends in the data. I am proficient at querying databases and transforming raw data into useable data. I am comfortable designing for the boardroom, printed materials, web sites, or simple pdfs and spreadsheets.

Web Design & Development

I focus on web standards, clean code, and uncluttered layouts. I’ve designed and developed a wide range of sites for commercial, non-profit, government, and art clients. These have spanned from simple marketing brochures to sites with 1000’s of pages and years of archives. My designs have ranged from punchy photographic layouts to sophisticated data-heavy internal dashboards and tools. I’ve used a wide variety of off-the-shelf and custom content management systems, and I take pride in working closely with my clients to build successful sites that meet their needs and put the user first. My experience includes:
