about
Who I am, short version.
Javier Sikora. Student. Based in Spain. Builds things on a Pi.
I go by Ekisde online. I'm a student who's really fucking bored The usual mix Python for nearly everything, some JavaScript when the browser can't be avoided, a bit of C++ when I want to feel things more directly, and enough x86 reverse engineering to be considered a skid
The thing I'm most into right now is AI that's actually useful tools trained on personal data, with the plumbing to put them in front of real users. That means bots that do one specific thing well, scrapers that feed them, and a small licensing system so I can share them without them walking off.
Security is the other half of my brain.
CTFs, reverse engineering, understanding how software breaks. At some point I wrote a full CS2 cheat from scratch which, no, is not going on a CV, but taught me more about memory manipulation and Windows internals than any textbook would've.
On the web side, this site is the project.
Ekisde.dev is a Flask app that self-hosts 24/7 from a Raspberry Pi two feet from my bed. Every tool you see around here the vault, the casino, the API, the key auth system, the fun pages, the admin I wrote because I wanted to learn how it worked. It's a junk drawer with a lot of care put into it.

things I've made
- This site full-stack Flask app self-hosted on a Pi. Vault, casino, API, key auth, fun pages, all from scratch.
- AI tools custom-trained models on personal data, with a licensing system to distribute them.
- Security / RE CTF writeups, reverse engineering, and low-level memory work in C++ and Python.
- Automation scrapers, bots, and scripts that handle the boring stuff so I don't have to.
