About

Backend and full-stack, owned end to end

I'm a senior software engineer based in Lahore, Pakistan. Over the past four years I've built and shipped backend services, full-stack web platforms and mobile products for companies including Blue Horn Technologies, SolutionWin Technologies, Technotz and Teraception. I like owning a feature all the way through — schema design, the API contract, the client application, and the deployment.

On the infrastructure side I run the production stack for my own SaaS myself: a multi-stage Dockerfile behind Nginx and Supervisor, a Docker Compose stack with MySQL and Redis on a private bridge network, TLS terminated at the proxy, and every credential externalised to environment variables. I've also moved live applications between hosting environments — shared hosting to VPS to AWS, including DNS cutover, SSL certificates and transactional email — and that work is the part most teams underestimate.

Lately I've been building AI-backed features into production systems: retrieval-augmented generation pipelines and Model Context Protocol (MCP) integrations, wired into real application workflows rather than demo scripts.

What I do

Where I add value

A senior engineer who can carry a feature from architecture through deployment, and who is comfortable owning the infrastructure it runs on.

Backend

API & service development

Laravel and Node.js/Express REST and WebSocket APIs. Token and OAuth authentication, payment gateway and third-party integrations, background jobs and scheduled work.

Mobile

Flutter applications

Android and iOS clients with Firebase backends, offline caching, push notifications and provider-based state management, shipped with a test suite.

Infrastructure

Docker, CI/CD and hosting

Docker and Docker Compose, Nginx reverse proxying, Linux server administration, deployment pipelines, hosting migrations, DNS, TLS and transactional email.

Design

System and database design

Monolith or microservices, scalable database schemas, query optimisation, and service boundaries chosen for the team that has to maintain them.

Integrations

Identity, payments and enterprise tools

Microsoft Entra ID (Azure AD), Microsoft Teams workflow and notifications, payment gateways, web3 wallet support and email routing for system alerts.

AI

AI inside real products

Retrieval-augmented generation pipelines and Model Context Protocol integrations, built into application workflows with evaluation and cost in mind.

Selected work

Projects I've built

Products I designed and shipped. Public repositories are linked where the client has allowed it; for commercial and NDA-covered work I can walk through the architecture on a call.

EquiSplit

Laravel 12 · Flutter · Docker

Expense splitting and group management, end to end. Sanctum token auth, Fortify 2FA and Google sign-in on the API; balances recalculated automatically and broadcast live over Soketi WebSockets, with push through Firebase Cloud Messaging. Runs on MySQL 8 and Redis behind a production Docker stack — PHP-FPM behind Nginx with Supervisor, and Compose services for MySQL, Redis and the websocket server on a private bridge network. Every credential is externalised to environment variables and the stack fails fast when a secret is missing.

Client app →

Bunny Doku

Flutter · Dart · Hive

A puzzle game built end to end: a constraint solver and level generator that produce 1,000 boards where the bundled solution is provably the only rule-legal answer, the runtime rules engine, a scrollable level map, rewarded and interstitial ads with tenure-based cadence, in-app purchases, and a remote-config content pipeline so new levels ship without an app release. Analyzer clean, with a unit-test suite covering placement validation and the bundled level pack.

Repository →

Showroom & Fleet ERP

Flutter · Firebase · Riverpod

Dealer and agency operations platform for a vehicle showroom. Inventory with fresh and used-bike document fields, sales with profit and dealer commission calculation, dealer and agency management with role-scoped access, and Hive offline caching. Around 67 Dart files, with tests covering the profit, commission and validation logic.

Repository →

Polus Network

Laravel 9 · Inertia · Vue

A Laravel platform served through Inertia and Vue, covering the full account and money-movement surface: deposits and withdrawals, currency swaps, subscription plans and their lifecycle, platform settings, and an admin dashboard over the whole thing. Sanitary API, token auth and a deployable Docker Compose stack.

Repository →

Otomo

PHP/Laravel · Node.js · Async pipelines

Automated marketing creative engine that generates video and banner advertisements. I built the backend and job-orchestration layer: asynchronous render pipelines, failure isolation per job so one bad render never stops the queue, per-tenant quotas, and the media processing and delivery path. The client is under NDA, so there is no public demo or code link — happy to walk through the architecture on a call.

Car rental & fleet SaaS

Laravel · MySQL

Cloud-based fleet, driver and booking management for a UAE car-rental group. I built the booking and dispatch core along with the fleet and driver admin surfaces: availability and scheduling logic, driver assignment, and document and expiry tracking for a regulated fleet operation. Client details are under NDA, so there is no public demo or code link.

Kiosk & repair workflow platform

Laravel · MySQL · Email routing

Operations platform managing repair workflows, technician assignments, parts usage tracking and automated system notifications. I built and extended it end to end: the repair workflow state machine, technician scheduling, parts consumption accounting, and an email-routing service for system alerts, deployed on managed Linux with DNS, TLS certificates and transactional email handled.

Sports analytics APIs

Backend APIs · Data processing

Backend APIs that fetch, process and serve sports analytics and event data to mobile clients, handling the ingestion and normalisation of upstream feeds before serving them to apps. Built for a commercial sports media product, so there is no public demo or code link — the architecture walkthrough is available on request.

WordPress themes & plugins

PHP · WordPress · WooCommerce

Themes, plugins and storefront customisations delivered for agency clients, covering template development, plugin behaviour, WooCommerce integrations and site installation and configuration on shared hosting. This was the core of my work at Glixen Technologies and it is where my PHP fundamentals came from.

Client feedback
