The five pillars

Flutter for mobile, Node.js for APIs, Next.js for web, MongoDB for document data, WordPress for business sites — one engineer from architecture to production support.

Cross-platform mobile

Production Flutter apps for government, enterprise, and consumer — built with Dart, Firebase, and REST APIs. One codebase, iOS and Android.

Backend & REST APIs

API layers, Dataverse wrappers, middleware, and services — Node.js backends that connect mobile apps and web frontends to enterprise data.

Modern web frontends

Server-rendered, SEO-optimised web experiences with Next.js, React, and Tailwind — fast, accessible, and designed for real users.

Database & data modeling

Flexible document schemas, user profiles, data shapes tuned for aggregates and dashboards, and API-ready collections — MongoDB as the data layer for modern mobile and web backends.

CMS & business websites

Full business websites designed and developed in WordPress with Elementor, WooCommerce, and ElementsKit — fast, manageable, and built to convert.

Also: .NET / C# · SQL Server · Dynamics CRM 365 · Firebase · Dart · DevOps — 24 years means the supporting cast is strong too.

About me

Experience & craft

I lead technical delivery at Ajman Chamber — Flutter mobile apps, Next.js web portals, Node.js services, and a Dynamics CRM 365 integration that holds it all together. I've been in this role for 11 years, which means I've dealt with the legacy systems, rebuilt what needed rebuilding, and shipped new products alongside it. Open to Flutter, Node.js, Next.js, and WordPress roles or freelance projects worldwide — remote or on-site.

“Most developers pick a lane.
Flutter or backend. Web or mobile. Frontend or API.”

I build the mobile app, the backend API, and the web frontend.
Then I support it in production, because I've been doing this for 24 years.

Software Tech Lead

Ajman Chamber of Commerce & Industry · UAE

Flutter Dart Next.js Node.js Dynamics CRM 365 Dataverse ASP.NET / C# SQL Server Crystal Reports Firebase

  • Built the Chamber's core digital products — Flutter apps for members, a Next.js web portal, Node.js services in the middle, and Dynamics CRM 365 as the data backbone. Designed the architecture and still write a significant portion of the code.
  • Built a Node.js API layer between the frontend and Microsoft Dataverse — handling authentication, request validation, and response shaping so the Flutter and Next.js apps have a stable contract regardless of what changes underneath.
  • Firebase covers the mobile-specific work: user authentication, real-time data sync via Cloud Firestore, and push notifications through Cloud Messaging.
  • SQL Server data modelling, stored procedure tuning, and Crystal Reports outputs for finance and operations teams.
  • Team lead: sprint planning, code reviews, branching strategy, and making sure engineers understand the reasoning behind decisions, not just the task.

Software Programmer

RAK Airport · Ras Al Khaimah

ASP.NET C# SQL Server Crystal Reports REST APIs IIS

  • Built and maintained the airport's public website and staff intranet on ASP.NET with SQL Server.
  • Wrote stored procedures, tuned queries, and produced Crystal Reports outputs used daily by finance and operations.
  • Managed role-based access controls and authentication for intranet modules handling sensitive operational data.
  • Migrated legacy .NET codebases to cleaner architecture without disrupting live systems.

Assistant Manager — IT

Takaful Pakistan Limited · Karachi

ASP.NET C# SQL Server Oracle Crystal Reports Agile SDLC

  • Built insurance modules for motor, fire, marine, health, and re-takaful — covering quoting, underwriting, policy issuance, claims, and settlement.
  • Data tier ran on Oracle and SQL Server in parallel. Crystal Reports handled regulatory outputs. Business rules encoded Sharia-compliant constraints directly into application logic.
  • Worked with QA through Agile iterations: test plans, defect triage, regression testing, release readiness.
  • Built shared component libraries to speed up feature delivery across policy, claims, and accounting modules.

Senior Web Developer · Graphic Designer

eWorld (Private) Limited · Karachi

Web development Graphic design HTML · CSS cross-browser delivery client projects

  • Client websites from brief to launch — visual design and development both. Six years, many clients, multiple industries.
  • Cross-browser layouts in the mid-2000s were difficult. Built a precision with markup and CSS that still shows in how I work today.
  • Managed client relationships directly: scope, timelines, content handoffs, and revisions.
  • Server-side scripting and database work alongside the front-end — before anyone called it full-stack.

Solutions

Use cases

Representative work from discovery and architecture through delivery, quality checks, and ongoing support — across government, aviation, and insurance domains.

Ajman Chamber of Commerce & Industry · UAE · Web

Member portals & internal tooling — Dynamics CRM & modern web stack

Dynamics CRM 365 Dataverse Web API Next.js Node.js Tailwind CSS REST APIs

The Chamber portal connects members to government services. Dynamics CRM 365 is the system of record — every member, transaction, and interaction lives there. I built a Node.js API layer between the frontend and the Dataverse API: it handles authentication, shapes requests, validates data, and gives the Next.js frontend a consistent contract.

The reason for the wrapper: Dataverse is unpredictable if you hit it directly from the client. The Node.js layer absorbs that complexity. The Next.js frontend stays simple and fast.

Ajman Chamber of Commerce & Industry · UAE · Mobile

Chamber mobile apps — Flutter & Firebase alongside enterprise backends

Flutter Dart Firebase REST APIs Node.js

The Chamber mobile app runs on Flutter — one codebase for iOS and Android. Firebase handles authentication and real-time data sync; Cloud Messaging delivers push notifications when members need to act. The app connects to the same Node.js services as the web portal, so both stay consistent with Dynamics CRM.

Getting the offline behaviour right took the most time. Members use this where connectivity drops — the app has to handle that without losing data or confusing the user.

RAK Airport · Ras Al Khaimah

Enterprise airport web properties & intranet systems

ASP.NET Crystal Reports SQL Server

Corporate website and staff intranet for an international airport — ASP.NET, SQL Server, Crystal Reports. The users were mostly internal: finance, operations, and management who needed reliable data and controlled access.

Aviation IT moves carefully. Releases were planned, tested, and rolled back if anything looked wrong. That discipline is still how I approach production deployments.

Takaful Pakistan Limited · Karachi

Insurance modules — underwriting through settlement

Motor Fire Marine Health Re Takaful
ASP.NET Oracle SQL Server

Five lines of Islamic insurance built from scratch: motor, fire, marine, health, and re-takaful. I built most of the modules across the full lifecycle — quoting, underwriting, policy issuance, claims, and settlement.

The complexity was in the data: Oracle and SQL Server in parallel, Crystal Reports for regulatory outputs, and business rules that had to be exact because auditors checked every number. This is the role that made me take data integrity seriously.

SavviSound · Wellness product

Mobile app (Flutter) with Node.js API & MongoDB

Flutter Node.js MongoDB

SavviSound is a consumer wellness app — habit tracking, hydration reminders, and personalised insights. I built the Flutter frontend and the Node.js backend. MongoDB stores user profiles and habit logs in a structure that queries cleanly for the analytics features.

Consumer apps are a different discipline from enterprise work. The user has no manual and will delete the app the moment something confuses them. That constraint changes how you think about every screen.
