Backend developer building scalable APIs and services with Node.js, TypeScript, and PostgreSQL. I love building things that live on the internet and sharing what I learn along the way. Based in Dharan, Nepal.
Follow me on Twitter for hot takes and half-baked opinions, stalk my code on GitHub where the real work happens, or connect on LinkedIn if you enjoy professional small talk.
Microservices-based chat application backend with 4 independent services: API Gateway, Auth Service (MySQL), User Service (PostgreSQL), and Chat Service (MongoDB + Redis). Polyglot persistence for optimized data handling.
More projects coming soon...
A lot of ideas are actively being designed and built right now. New open source projects will be added here soon.
Snapshots from my LinkedIn feed — quick notes, experiments, and lessons.

Most ORMs give you one way to query. Drizzle gives you two.
The 𝗦𝗲𝗹𝗲𝗰𝘁 𝗔𝗣𝗜 is explicit. You describe exactly what SQL you want. It offers full control, but you end up writing manual joins every time related data is needed.
The 𝗤𝘂𝗲𝗿𝘆 𝗔𝗣𝗜 is declarative. You define relations once and then just say what you want back. Drizzle figures out the SQL for you.

Starting a new project - Blogify, a blog platform built on Hono + Cloudflare Workers.
Before writing any code, I designed the full database schema. Every table has a reason.

𝗣𝗮𝗿𝘁 𝟮 of migrating my Express + Render API to Hono + Cloudflare Workers.
Part 1 was about implementing AES-256-GCM encryption using the Web Crypto API.
This one is about routers/routing in Honojs.

Most of us write fmt.Println("Hello World") or printf("Hello World") ,and assume magic happens. But under the hood, there’s a fascinating "Game of Thrones" happening between your compiler, the OS, and the Kernel.

After weeks of focused development, I’ve built a great backend system for a notice board application — designed to handle real-world complexity, not just CRUD.
Late 2025 was the start of my backend journey using Express and TypeScript.
Started building backend APIs with Express
Applied TypeScript across server-side code
Focused on architecture, API design, and clean project structure
By mid 2025, I doubled down on JavaScript and began learning TypeScript seriously.
Early 2025 marked my pivot to JavaScript, and it quickly became my main area of focus.
Late 2024 is where it began with my first Hello World and early practice projects.
