#015Web · Done
Base64 Asset Bloat
Learned: A single embedded image can 30x an HTML file's size — always ship binary assets separately, never inline.
#014Web · Done
P2P Multiplayer for RPS
Learned: Two players who are both online at once barely need a server at all — a direct peer connection is enough.
#013Web · Done
Cipher Machine Simulators
Learned: Rotor-stepping logic is the entire trick to a working Enigma sim — everything else is just UI around it.
#012Web · Done
Icon System Without Images
Learned: Ten hand-built inline SVGs load faster and theme easier than any icon font or image sprite.
#011Web · Done
Offline-First PWA
Learned: A service worker makes "works with no signal" a real, testable claim instead of a nice-to-have.
#010Web · Active
Shared Hosting Quirks
Learned: Free hosts can silently drop oversized files during extraction — always verify what actually made it to the server.

About
Hi, I'm Makan.
I'm MAKAN — I build Android apps and web tools, mostly solo, mostly at night.
I like software that does one thing well: fast to open, honest about what it does, and built without unnecessary dependencies. Most of what's on this site started as a problem I wanted solved for myself first — a conversion I needed, a cipher I wanted to understand, a game I wanted to finish.
