Data Analyst & R Developer
Finland
I'm a data analyst and R developer who loves exploring data, creating visualizations, interactive applications, and sharing what I learn along the way. I work primarily with R, Shiny (for the apps), and the tidyverse ecosystem (including ggplot2 for data visualization). I also work with Power BI (including DAX, M, and the rest).
Finnish library opening hours on a map, with open or closed status that updates every minute, nearest-open-library search, 240+ service filters, shareable links, and service statistics. Data is refreshed nightly from the Kirkanta API into Turso (cloud SQLite)
Nearest Helsinki and Espoo city bike stations with live bike counts, on a list or a map. Search, favorites, directions, and color-blind-friendly status colors
A new AI-generated image every day, inspired by a real event from that date in history. Events come from Wikipedia's “On this day” list, written up with GPT-5.6 Luna and drawn with GPT Image 2.5 Sunburst. Full-screen lightbox and arrow-key browsing
Your Spotify listening habits: top artists, tracks and genres for various time ranges, recently played, and all your playlists (thousands are fine). Create playlists from your favorites and download shareable stats cards
Describe the music you are in the mood for and get an artist recommendation: OpenAI (GPT-5.4 nano) understands the request, Spotify supplies the artist card. Honorable mention in the Posit 2024 Shiny Contest
