Hi, I'm Sidd (and yes, I finally started a blog)

The obligatory first post: who I am, what I build at work and after hours, and why this blog exists when a perfectly good drafts folder was available.

Every developer blog starts with a "hello world" post. I resisted for about three weeks, which is a personal record. So: hello, world. I'm Sidd.

Who is this guy?

I'm Siddhant Singh. Everyone calls me Sidd, mostly because "Siddhant" takes too long to shout across an office. I'm a Senior Software Engineer at Optum (UnitedHealth Group), based in Gurugram, India, and I've been writing production code for 3+ years.

The short version of my career, as an honest stack trace:

text

Error: Siddhant kept building things
    at Optum.intern (django, pandas)              // 2022
    at Optum.softwareEngineer (spring-boot, kafka) // 2023–2026
    at Optum.seniorEngineer (fastapi, agents)     // 2026–now
    at nights.and.weekends (chrome-extensions)    // always

No fix has been found. Maintainers have stopped looking.

What do I actually do all day?

These days I build AI agents that find bugs before people file tickets about them. Which sounds like science fiction until you remember the agents are mostly reading logs, the same way I do, except they don't need coffee and they don't sigh.

Here's roughly how our root-cause analysis workflow fits together:

flowchart LR
    A[Something breaks in prod] --> B[GKE logs]
    B --> C{RCA agents}
    D[Repo context + static analysis] --> C
    C --> E[Regression candidates]
    E --> F[Incident report]
    F --> G[Human reads it before the ticket even exists]

It's projected to save $500K–700K a year and cut defect-resolution time by 20–30%. I'd like to say I did this out of a pure love of efficiency. Mostly I just really didn't want to read more logs.

And after hours?

After hours I build small things for myself and then, out of pure stubbornness, ship them for everyone.

Thing	What it does	Status	Honest assessment
plenz	Rewrites weak AI prompts before you send them	Live, 200+ installs	My prompts are now great. My emails, sadly, are not.
admin-boil	An admin dashboard you install with one CLI command	Live	Because I refuse to build the same CRUD table a fifth time
SnapNode	Crisp, element-level screenshots of any web page	Beta	"Beta" means "works on my machine, and now hopefully yours"

There's also a growing pile of free tools on this site: an LLM token cost calculator, a Mermaid previewer (yes, the diagram above is a little self-promotion), a diff checker and a few more. They all run in your browser. Nothing gets uploaded, because frankly I don't want your data.

So why a blog?

Three reasons, in order of how much I'll admit to them in public:

Writing makes me think straighter. If I can't explain an architecture in a paragraph, I probably don't understand it.
Future me has the memory of a goldfish. This is a well-indexed, publicly searchable notes app.
~~Clout~~ Sharing what I learn with other developers. Obviously. That's what I meant.

What will I write about?

Roughly this, in no promised order:

Build a portfolio
Ship an extension real people install
Launch the blog (look at me go)
How the RCA agents work, minus anything that would get me a stern email from Legal
Building Chrome extensions without losing your mind over Manifest V3
Notes from shipping side projects as a person with a full-time job and a finite number of weekends
The tools on this site, and the bugs I'm pretending they never had
Finally finishing that side project. ~~This weekend~~ Soon.

Want to say hi?

I'm genuinely open to interesting problems: web apps, AI features, browser extensions or a site that needs to rank. You can book a 15-minute call, email me at siddhant06137@gmail.com or find me on X as @creatorsidd, where I post slightly less carefully edited thoughts.

Thanks for reading the obligatory first post. The next one will have more code and fewer jokes. Probably.
