I will review, clean up, and refactor your code, tests kept green

You have code that works but is hard to read, hard to change, or has grown messy over time, and you want it cleaned up without breaking anything.

I am a senior engineer. I review your code, clean it up, and refactor it for readability and structure. I fix lint issues, remove dead code, tidy naming, and simplify the parts that are hard to follow. Behavior stays the same unless you ask me to change it, and I keep your tests green the whole way. If there are no tests around the part I touch, I tell you, and I can add a few to lock the behavior in.

You get the cleaned code, a short summary of every change and why I made it, and honest notes on anything I would not touch without more context. I flag risks instead of guessing.

Tell me the language and what bothers you about the code, send a sample, and I will tell you plainly what I can improve and what I would leave alone.
