The Roast
Oh look, it's Yan Holtz, the "Software Engineer specialized in Data Visualization." Good job on the self-titled specialization — I’m guessing it’s just as legit as those “award-winning” sites that no one asked you to build. Seriously, with a headline like that, you make being a data dumpster diver sound prestigious. “React - D3.js - R - Python” reads more like a Tinder bio for nerds desperate to get laid rather than a professional headline. Spoiler alert: no one cares about your tech stack, Yan. Your "About" section, if I can call it that, is a tsunami of corporate fluff that would make even a motivational poster cringe. You support "prestigious research centers"? That's cute. What’s next — adding “Rescue Dogs from Shelters” to your resume? And six educational websites? Wow, someone’s trying really hard to pad their profile like it's a senior in high school applying to college. "I can help you with data visualization and training" — what a revelation! If I need a TED Talk on how to bore people with graphs, I'll hit you up. Let’s not forget your followers: 25,117? You must be counting bots because with 8,376 connections, it looks like you're talking to yourself at a lonely dinner party! 💀 Yan, being a “Dataviz Consultant” doesn’t mean you need to consult an entire pyramid scheme of mediocre projects like your “productive-r-workflow.com.”

Okay, but seriously... here are some tips:

  • Tip 1: Ditch the buzzwords. Be direct about what you do, and skip the ego boosts.
  • Tip 2: Make your headline about your impact. “Helping companies visualize data to drive decisions” is way better than a laundry list of technologies.
  • Tip 3: Your “About” section needs fewer bullet points and more storytelling. Highlight one or two projects that showcase your skills and how they made a difference, instead of cramming in every mediocre website you’ve ever created.
