Umar Hashmi
Founder & Editor, VNHAX · Full-Stack Web Developer & UI/UX Designer
About Me
I'm a full-stack web developer and UI/UX designer. I have worked as a freelancer since 2018, building websites and web apps mostly with React, Next.js, Node.js, Express and MongoDB, and designing the interfaces for them.
Since 2022 I have been building AI-powered tools and automations with the OpenAI and Gemini APIs, and I use AI coding assistants and editors such as Claude, Cursor and Windsurf in my daily work.
I started VNHAX in October 2026 to explain new AI models, developer tools and open-source projects in plain English, with links to the original sources so you can check everything yourself.
My Setup
When an article says I tested something myself, it was on this hardware:
- Laptop: Alienware x15 R2
- CPU: 12th Gen Intel Core i7-12700H
- GPU: NVIDIA GeForce RTX 3070 Ti Laptop GPU (8 GB VRAM) + Intel Iris Xe integrated graphics
- RAM: 16 GB
- OS: Windows 11 Pro (64-bit)
How I Write
I base articles on official announcements, documentation and pricing pages, and link to them so you can check the details. When I have tried something myself I say so; when I haven't, the article is an explainer. I use AI tools for research and drafting, and I review and edit everything before it is published. Read the full Editorial Policy.
