I built a football bot that doesn't watch football. It's #2 in our World Cup league.

The bot is sitting in second place out of fourteen. Three points behind the leader. The thirteen humans in this league watch a lot more football than I do, and the leader watches more football than most of them. The bot has never seen a match. The setup A friends-only prediction league, World Cup 2026, thirteen humans and one bot. The league is private, so I won't link it. The bot's name in the standings is "mike," same as mine, which the others find funnier than I do. I wr...

Why I'm Building a Social Media Tool After 15 Years of Coding

Here's a stat that changed everything for me: a single reply on someone else's tweet is worth 13.5x more than a like in the algorithm . Not 13.5% more. 13.5 times. I discovered this by accident four months ago. At peak, I was pulling 332,000 weekly impressions on Twitter. Zero ad spend. Zero threads. Just replies. My best reply got 1,300+ likes. Most of my original posts couldn't crack 100 impressions. The ironic part? I'm the guy building a social media tool. And I was getting more tract...

Lugn - The distraction blocker that's actually on your side

Introducing Lugn Lugn (Scandinavian for "calm") is a privacy-first browser extension that helps you build real focus habits - without the guilt. No hard locks. No punishment. Just a simple, mindful nudge: "Are you sure you want to visit this site?" Yes or no - your choice. Always. Why L...

How I killed my fragile Instagram scraper and collapsed data collection into one API call

I'm building Mimestra — it finds viral short-form videos, breaks down why they went viral, and turns that into a shoot-ready brief. This post is about one infra decision that saved the project. The cheap path that bit me For Instagram data I went the obvious cheap route: a burner IG account + instagrapi , self-hosted. Great in testing. Then, right as I onboarded first users, the account got suspended. No data, broken product, worst timing. If you've scraped IG yoursel...

How I A/B test LLM prompts without fooling myself

A while back I was building a support assistant and hit a simple-sounding question: is this new version of the prompt actually better than the old one? So I did the obvious thing. I wrote thirty test cases, ran both prompts, saw the new one score a little higher, and shipped it. I felt great about it for half a day, until the support queue filled with complaints and I was rolling the change back from a Slack thread that evening. The bump in the score was never real. The test was far too sm...

The interview questions candidates score worst on are not the ones they prepare for. Real data from 816,000 sessions explains why.

The interview questions candidates score worst on are not the ones they prepare for. Real data from 816,000 sessions explains why. Every software engineer who has spent months preparing for technical interviews knows the routine. LeetCode problems in the morning. System design walkthroughs in the evenings. Mock interviews on weekends. By the time the actual interview arrives, candidates can reverse a linked list, design a distributed cache, and explain the tradeoffs of eventual consistency...

🚀 I Built an AI Team That Finds Leads, Decision Makers & Writes Outreach While I Sleep

Lead generation is one of those tasks everyone knows they should automate… but most teams still do it manually. Every week the process looks something like this: 🔎 Search LinkedIn for companies 🌐 Visit dozens of websites 👤 Find the CTO, VP, or Director 📧 Hunt for contact information ✍️ Write personalized outreach emails ⏳ Lose half a day doing repetitive work What if all of that happened automatically? What if you woke up Monday morning to find: ✅ A list of companie...

I Measured MCP vs Direct API Calls: The Token Math No One Tells You

MCP is having its moment. Every agent framework is wiring tools through it, and for good reason: standardized tool registration, composable servers, a protocol that doesn't force you to reinvent the plugin system every project. I get the appeal. What I didn't see coming was the token bill. Here's the number that stopped me cold: for a simple SerpApi search, an MCP agent used 6,047 tokens per call . A CLI script doing the exact same job used 351 tokens . That's 17x overhead, for the same ...
