Mian Ali Khalid

Software engineer. Builder of Xerobit. Focused on developer tooling, web performance, and shipping things that work.

About

I'm a working software engineer who got tired of slow, ad-riddled developer-utility sites and built my own. Xerobit is the result — a focused suite of tools for the tasks I do daily: format JSON, decode tokens, test regex, pick colors, and so on. Every tool runs 100% in your browser. Every page loads in well under a second.

I care about the details that don't get surfaced on most tool sites: precise RFC compliance (URL encoding, JSON grammar), meaningful error messages, keyboard shortcuts, and speed.

What I work on

• Xerobit — this site. Every tool, every post.
• Open-source — find me on GitHub.
• Professional work — software engineering; see LinkedIn for details.

Topics I write about

• JSON, YAML, and serialization formats
• Encoding (Base64, URL, Unicode, quoting rules)
• Regex and parsing
• Timestamps, timezones, and calendar math
• Web performance (Core Web Vitals, INP, bundle size)
• Developer experience and tooling
