''Curiosity is the engine of achievement''

About Me

Hi, I'm Loris.

By day I wrangle data and write SQL queries. By night I'm lost in a book, a habit that's been with me since I was a kid. If you can't find me, I'm probably on the floor with my laptop. Yes, actually on the floor. Something about it helps me think. My friends call it weird. I call it productive eccentricity.

When I get deep into a problem, I tend to pace around and talk to myself like a human fidget spinner. That same energy comes out when I'm discussing books or tossing around ideas with open-minded people who don't mind the occasional philosophical tangent.

I'm a little shy at first, but once that melts away I'm the friend who checks in regularly and genuinely wants to know how you're doing. I'll even watch TV series with you, though I secretly believe books are better, after all, you can control the pace.

Lately I've been on a bit of a self-discovery journey. Like most people, I sometimes find myself wondering where I fit in and what unique perspective I can bring to the table. I don't have it all figured out (who does?), but I'm starting to see that understanding yourself is a lot like reading a great mystery: you're both the detective and the main character.

Corsica: The Other Mediterranean Jewel

Seven days discovering France's island paradise

Just returned from a week in Corsica and I'm convinced it's Sardinia's equally beautiful twin sister. The island offers everything you'd expect - stunning beaches, crystal-clear waters, and genuinely warm locals who made every interaction memorable. While the famous beaches like Palombaggia were predictably packed, the real magic happened during those spontaneous hikes that led to completely secluded coves. Sometimes the best discoveries come from simply walking away from the crowds.

Benevolenza Cosmica by Fabio Bacà

A delightful read about extraordinary luck

During my holidays I read Benevolenza Cosmica by Fabio Bacà. The story follows Kurt O'Reilly, a statistician who spends three months experiencing nothing but good luck, as if everything around him is perfectly aligned. The writing is smooth and easy to follow, the plot is funny and engaging, and the ending is surprising but fits perfectly with his journey. I definitely suggest this book if you want a break and are looking for something light and enjoyable to read.

My Sudoku Obsession

Falling down the Cracking The Cryptic rabbit hole

I've become completely hyperfixated on sudokus after discovering Cracking The Cryptic on YouTube. Watching Simon Anthony solve the most impossibly complex variant sudokus is both inspiring and humbling. I'm now attempting to solve puzzles before watching his solutions, but there's clearly a massive gap between my amateur skills and his genius-level pattern recognition. The journey from basic 9x9 grids to sandwich sudokus and killer variants has been addictive.
