New markets, strategic partnerships, and revenue channels you haven't tapped yet. I help you identify growth opportunities and build the relationships that turn them into real business.

Dashboards that tell you what to do, not just what happened. I turn your raw data into clear, actionable insights — so every marketing decision is backed by evidence, not guesswork.

Reaching 2400 Bullet on Lichess — and Beating a 3000+ Rated Player
I have been playing chess online since I was 13. I am 38 now, so that is 25 years of online chess across platforms like Spelpunt.nl, Playchess.com, ChessCube, Chess.com, and Lichess. For most of that time I played casually — fast games, lots of bullet, always enjoying it but never thinking too much about ratings. Then recently two things happened that I feel compelled to write about: I hit <strong>2400 bullet on Lichess</strong>, and shortly after I went <strong>2-2 against a 3000+ rated bullet player</strong>. I still can't fully believe the second one happened.

Multi-Tenant SaaS with Supabase: How Row Level Security Replaced My Custom Auth Middleware
When I started building the Webfluentia dashboard, my first instinct was to handle data isolation in application code. Check the user's role, filter queries by client ID, add middleware to every API route. It worked, but it was fragile — one missing filter and a client could see another client's data. Then I discovered Supabase Row Level Security (RLS), and it changed how I think about multi-tenant data isolation entirely. Instead of trusting application code to filter data correctly, the database itself enforces who can see what. Even if my code has a bug, the wrong data never leaves PostgreSQL. Here's how I implemented it and what I learned.
