Hi! 👋 I'm Alisa Sireneva (she/her), a software developer and blogger from Moscow.

I specialize in performance optimization and systems programming. I also have experience with security, compression, and decentralized systems.

My primary goal as a writer is to teach the concepts I regularly apply through accessible content. You might recognize me from bangers like:

• The RAM myth
• Bad Apple!! in Minecraft
• WebP: The WebPage compression format
• I sped up serde_json strings by 20%
• Why performance optimization is hard work
• You might want to use panics for error handling

My blog is right here. If you know Russian, check out my Telegram channel as well.

Trivia

I love listening to Badflower and LukHash.

My favorite book is Worm. My favorite modern-day author is qntm.

My favorite color is #8f1fff.

I still haven't completed Celeste.

I use a basic Arch setup because I don't like wasting time.

I'm nostalgic over the good old days I've never seen and love retrocomputing.

My stack

I'm familiar with:

• Frontend: basics (HTML/CSS/JS), TypeScript, React, Vite
• Backend: Flask, Rocket, Axum
• Linux: basic sysadmin stuff, systemd, funny hacks
• Systems programming: mainly Rust, also C, C++, a bit of Go
• Low-level: Linux modules, x86 assembly, compiler internals
• HPC: experience optimising code for x86, e.g. mod2k or these posts
• Algorithms & data structures: competitions, applied and invented algorithms
• Networking: experience with ZeroNet
• Information security: CTFs and sandboxes used in production
• Open-source: contributed to Rust libraries and other projects, released many myself
