Who I am

I'm a software engineer who likes taking an idea from a blank editor to something people actually use. Right now I build software at NuvertOS — Angular on the front, Node.js and PHP over MySQL behind it.

Before that I shipped Flutter apps: a campus-fest app on the Play Store and App Store, hackathon products, and a handful of side projects. I care about the details that make software feel fast and considered.

Open to work and collaboration. If you're building something interesting, let's talk.

Things I've written

System Design·1 Aug 2026·8 min

Content Delivery Networks, from scratch

Why CDNs must exist (it comes down to physics), how a request finds the nearest edge, how caching and invalidation really work.

Saga Orchestrator·25 Jul 2026·8 min

Chapter 1 — The Solution: The Saga, and the Questions I Answered First

You can't make cross-service work atomic — so instead of one big transaction, you run a sequence of local ones with compensations: a saga. This chapter is that solution, and the five design questions I had to answer before writing a single line of SQL.

Saga Orchestrator·25 Jul 2026·7 min

Chapter 0 — The Problem: When One Order Isn't One Transaction

A batch of orders from a CSV looks like a trivial import — until you notice each order spans four services and there's no transaction to make it all-or-nothing. This is the distributed-consistency problem in full, before any solution.
