Software development services

Reliable full-stack development for startups, SMEs and digital agencies anywhere — web apps, marketplaces, e-commerce and mobile, built and shipped end to end.

Honest positioning: Remote development, worldwide. A senior team based in Pakistan that works across your business hours, with daily overlap for stand-ups, calls and reviews. Competitive rates, senior delivery.

What I build

Web app development

Custom web applications built end to end with Next.js, React and TypeScript — fast, accessible and built to scale.

Backend & APIs

Robust REST APIs, auth, payments and admin tooling in NestJS, Django and FastAPI, with PostgreSQL and message queues.

E-commerce & marketplaces

Multi-vendor marketplaces, storefronts, carts, checkout and Stripe escrow payments — the exact stack behind Barqibazar and Afro Market.

Mobile apps

Cross-platform iOS + Android apps in Flutter, sharing one API with your web product so features ship to both at once.

DevOps & deployment

Dockerised deploys, CI/CD, Nginx, AWS and self-managed VPS setups — reproducible releases and painless rollbacks.

Maintenance & support

Ongoing feature work, monitoring, bug fixes and performance tuning on a retainer or day-rate basis.

Selected work

BarqiBazar — local shop POS → online marketplace with delivery. One platform that takes a local shop from an offline-first POS to an online store with its own delivery fleet — desktop POS, CouchDB catalog sync, customer + rider apps, and four operations portals.
Afro Market (EFG) — B2B cross-border trade marketplace · UAE ↔ Africa. A cross-border B2B trade marketplace moving real money through Stripe escrow — an 8-service NestJS backend, real-time chat, a 5-language web app and Flutter mobile apps.
Nuxused — multi-tenant school management SaaS. A multi-tenant school-management SaaS — platform control plane, per-school portals and one Flutter app for parents, teachers and students.
KhaliSeat — intercity ride & empty-seat marketplace. An intercity ride & empty-seat marketplace — drivers post their spare seats, travellers search by route, date and gender and book a ride.

How I work

Discovery — We scope the problem, users and success metrics, and agree a clear plan and estimate before any code.
Design & architecture — Data model, API design and UI flows — the decisions that keep the build fast and future features cheap.
Build — Iterative delivery in short cycles, with a shared board and regular demos so you always see progress.
Test & review — Automated tests, code review and a staging environment you can click through before anything ships.
Deploy — Containerised, zero-drama releases to AWS or a VPS, with monitoring and reproducible rollbacks.
Support — Ongoing maintenance, new features and quick turnaround on issues — across your working hours.

Ways to work together

Fixed-price project — Best for well-defined scope

A clear brief turns into a fixed quote and timeline. You know the price up front — no surprises.

Day rate / retainer — Best for ongoing work

A predictable monthly or day-rate arrangement for continuous development, features and support.

Team augmentation — Best for agencies & scale-ups

Slot senior remote engineers into your existing team and tools to add capacity fast.
