Frequently asked questions
What clients ask before hiring me, and what developers ask about the services and free tools on this site.
Hiring and working together
What services do you offer?
I build full-stack MEAN applications: server-rendered Angular front ends, Node.js and Express REST APIs, MongoDB data models, e-commerce platforms with Stripe checkout, real-time features over WebSockets, Ionic hybrid mobile apps, and the Docker and nginx setup to deploy them. See all services.
Which tech stack do you work with?
Mainly the MEAN stack in TypeScript: Angular (SSR, NgRx, RxJS, Angular Material, PrimeNG, Tailwind CSS), Node.js with Express and Zod, and MongoDB with Mongoose. For mobile apps I use Ionic and Capacitor; for payments and maps, Stripe and Google Maps.
Are you available for freelance projects?
Yes. I take on freelance and contract work, from new builds to features for existing Angular or Node.js apps. Send a short brief through the contact form and I usually reply within a day.
What time zone do you work in?
I am based in Pakistan and work on Pakistan Standard Time (PKT, UTC+5). I already work with clients abroad: the serves a city in Connecticut, USA. I communicate in English by email and chat.
Can you take over or modernise an existing project?
Yes. Several of my projects were rebuilds: Wavy Cables was a near-total rewrite of a 2024 build on Angular 21 with SSR, and AA Bridal Studio was redesigned from a 2024 build onto Angular 21.
How do we get started?
Send a short description of what you need, where the project stands today and any deadline, through the contact form or by email. I usually reply within a day, and we agree on the scope before any work starts.
