Why I Switched from npm to pnpm (And Why You Should Too)

Fri, 03 Apr 2026 10:00:00 +0530

If you write JavaScript or TypeScript professionally, you’ve used npm. It ships with Node.js, it’s everywhere, and for years it was the only game in town. But after running npm on real-world projects — enterprise monorepos, Next.js apps, Angular dashboards, CI pipelines that bill by the minute — I can tell you: npm is holding you back.

Sat, 03 Jan 2026 10:00:00 +0530

Every developer hits the same wall eventually. You are building a webhook integration, testing an OAuth flow that demands a public redirect URI, or trying to show a client a work-in-progress without deploying it. Your app is running fine on localhost:5000, but the outside world cannot reach it.

Adding .NET Aspire to an Existing Clean Architecture Project

Sat, 20 Dec 2025 10:00:00 +0530

The infrastructure overhead in microservices projects is real. Setting up databases, wiring service discovery, getting distributed tracing working, managing connection strings across environments—this work hits before you’ve written a line of business logic. On more than one project, I’ve watched the first sprint disappear into Docker Compose files and appsettings drift.

Deploying Ollama with Open WebUI Locally: A Step-by-Step Guide

Sat, 11 Jan 2025 09:00:00 +0530

Introduction
#

Large Language Models (LLMs) have become a cornerstone of modern AI applications, from chatbots that provide customer support to content generation tools for images and videos. They power virtual assistants, automated translation systems, and personalized recommendation engines, showcasing their versatility across industries. However, running these models on a local machine has traditionally been a complex and resource-intensive task, requiring significant configuration and technical expertise. This complexity often deters beginners and even intermediate users who are eager to explore the capabilities of LLMs in a private, local environment.
