Selected Work
How I Build Flutter Products
I understand the product, choose a practical structure, build carefully, and support testing and release.
.01
Product & Codebase Understanding
I begin by understanding the users, business requirements, existing architecture, APIs, release constraints, and the specific outcomes the product needs to achieve.
.02
Practical, Scalable Architecture
I structure features, state, data flows, and integrations around the product’s actual complexity-using approaches such as Clean Architecture, MVVM, BLoC, Riverpod, or GetX where they provide clear value.
.03
Implementation, QA & Release
I build in focused increments, coordinate with product, design, backend, and QA, test critical flows, resolve performance and release issues, and support delivery to Google Play and the App Store.

As a Senior Manager at Dawood Family Takaful, I had the pleasure of working with Sufiyan Razaq on developing an agent app for our company. Sufiyan's expertise in Flutter development truly stood out throughout the project. His responsiveness, problem-solving skills, and attention to detail made the development process smooth and efficient. As the API developer on our team, I collaborated closely with Sufiyan, and I was consistently impressed by his technical proficiency and dedication to delivering a quality product. We are extremely pleased with the final app and look forward to future projects with him. Highly recommended!
