Flutter Developer │ Mobile App Developer │ Payment Gateway │Software Developer │ Fintech │ Dubai
Job Details
I am Rizvin K Salim, a passionate and results-driven Flutter Developer with over 3 years of professional experience building high-performance, cross-platform mobile applications for fintech clients across the UAE and Qatar. I specialize in developing production-level apps for Android, iOS, Windows, and MacOS using Flutter and Dart, with a strong focus on clean architecture, performance optimization, and seamless user experience.
Throughout my career, I have worked extensively in the fintech domain — building and maintaining apps for remittance, forex exchange, utility payments, and financial transactions. I have deep hands-on experience integrating UAE-specific SDKs and authentication systems including UAE PASS and Emirates Face Recognition (EFR), making me uniquely equipped to deliver compliant and secure mobile solutions for the UAE market.
On the payment side, I have successfully integrated major payment gateways including MyFatoorah and QCB (Commercial Bank of Qatar) into production mobile applications, ensuring smooth and secure transaction flows for thousands of end users.
One of the highlights of my career has been my onsite client engagement experience across the GCC region. I spent 4 months working onsite with a UAE-based client in Abu Dhabi, where I delivered a full production Exchange App, handled direct client communication, led demo sessions, and participated in daily stand-ups and sprint planning. I also spent 6 months onsite in Doha, Qatar, where I collaborated closely with financial stakeholders to build and maintain an Exchange Mobile Application, improved app performance and caching systems, and ensured API reliability for real-time exchange rates.
These onsite experiences have given me strong communication skills, the ability to work directly with clients and business stakeholders, and a deep understanding of how to deliver mobile solutions in fast-paced, high-stakes fintech environments.
On the technical side, I am proficient in:
- Flutter & Dart for cross-platform development
- State Management: BLoC and GetX
- Firebase: Analytics, Authentication, Cloud Messaging, Remote Config, Realtime Database
- REST APIs and gRPC integration
- SDK Integrations: UAE PASS, EFR, Meta (Facebook SDK), BILRS, DIDIT
- Payment Gateways: MyFatoorah, QCB
- Tools: Postman, Git, Figma
- Clean Architecture, Agile Development, Performance Optimization
Beyond technical skills, I have demonstrated leadership within my team. I was honored with the Employee of the Month award in December for leading a key client project to great success, and the Trainer of the Month award for mentoring junior Flutter developers during an in-house training program. These recognitions reflect my commitment not just to writing great code, but to uplifting the people around me and delivering real business value.
I hold a Bachelor's degree in Computer Science (B.Tech) from KMEA Engineering College (2019–2023), where I was actively involved in the IEDC and served as Media Head for the Eco Club. I also attended Finnovation 2025 in Qatar, staying current with the latest trends in the fintech industry.
I am currently based in Dubai and available to join immediately. I am highly motivated to bring my fintech mobile development expertise, GCC onsite experience, and passion for building impactful apps to a forward-thinking company in the UAE.
I am confident that my background, skills, and work ethic make me a strong fit, and I would welcome the opportunity to discuss how I can contribute to your team.
Thank you for your time and consideration.
