About Me
Hi, I’m Mabs 👋. For the past five years, I’ve been building and scaling mobile and web applications across industries like social commerce, on-demand services, e-commerce, social networking, and blockchain-enabled platforms. I’ve led projects from idea to production that now serve 100,000+ registered users, with multiple apps reaching 50K–70K active user bases and generating real commercial traction. I thrive in startup and distributed team environments, where I focus on clean architecture, CI/CD automation, and Agile workflows to ship secure, maintainable, and high-performing applications. Beyond just writing code, I enjoy bridging mobile and backend systems to ensure products are not only functional, but scalable and ready for growth. My work reflects a passion for turning ideas into impactful products that make a difference.
Technical Skills
Work Experience
Led the end-to-end technical evolution of Hafar Social from its early Firebase-based prototype into a scalable production platform now serving over 40,000 active users. Orchestrated a zero-loss migration of millions of records from Firebase Firestore and MongoDB to a robust Django + PostgreSQL infrastructure, ensuring long-term scalability and reliability. Designed and implemented high-traffic server architectures capable of processing 20,000+ daily data transfer requests between mobile and backend systems. Beyond engineering, I established technical roadmaps, mentored new developers, and spearheaded feature planning including AI-driven integrations positioning the platform for continued growth and resilience in a high-demand startup environment.
Founded and led the development of Sellio, a social commerce platform blending the community-driven engagement of Instagram with the marketplace functionality of Amazon. Architected and built the full stack (Flutter, Django, PostgreSQL, AWS) to support features including real-time chat, community feeds, video uploads, product listings, escrow-based payments, and secure order management. Successfully grew the platform to 500+ signups within the first two weeks and onboarded 20+ paying customers in the first month post-launch, validating product-market fit and demonstrating early revenue potential.
Led and mentored a team of four Flutter developers, driving the delivery of multiple production-grade mobile applications. Architected and launched two flagship on-demand service platforms (Click & Click Provider), enabling seamless connections between users and service providers (e.g., cleaners, home services) with robust real-time booking and payment flows. Established a scalable and maintainable foundation using Clean Architecture, GetX, and Dartz, which became the company’s standard for Flutter projects. Collaborated directly with Dumyah’s engineering team to accelerate development of their e-commerce platform, now serving over 100,000 active users across Android and iOS. Successfully shipped four additional apps during my tenure, ensuring consistent quality, performance, and adherence to best practices in mobile architecture.
Worked as part of a team of 5-6 Flutter developers to design, build, and maintain multiple mobile apps for Ultaininity Global. Developed core features including contact management modules, synchronization of user contact lists, secure user authentication flows, and integration of push notifications and background data sync. Collaborated closely with backend teams to debug API responses, optimize data loading, and improve UI responsiveness. Ensured code quality through unit testing and adhered to clean, modular architecture patterns. Helped improve app stability and reduce crash-rates, contributing to better user experience across Android and iOS.

What They Say About Me
"I’ve worked with Mabs across multiple companies and projects, from our early days at Primetag to now at Terkuaz Software. Over the years we’ve shipped several live products together, each serving thousands of users, and the reason I keep coming back is simple: trust. In this industry, it’s rare to find someone who not only delivers but also takes ownership of solving problems, even when the path isn’t obvious. With Mabs, I know that if I describe what needs to be done, he’ll figure out the best way to achieve it quickly and reliably. That trust is why he remains one of my go-to people whenever I need critical work done right."
Aseel Sawalmeh
CEO, Terkuaz Software
"I’ve had the pleasure of working with Mabs over the past three years on several projects. What sets him apart is his ability to take a brief, run with it, and deliver exactly often exceeding expectations. He deeply understands product goals, asks the right questions early, and solves challenges proactively without needing micromanagement. His reliability and commitment make him someone you want on every project, especially when timelines are tight and quality matters."
Anna Kowalski
Product Owner, Skylite Solutions (Poland)
"Working with Mabs was a fantastic experience. His attention to detail is exceptional — what we designed in Figma was implemented pixel-perfect and the interaction polish matched our product vision. He thinks in systems, proposing architecture improvements that reduced rework and made the app easier to maintain. Best of all, he requires minimal direction: give him a goal and he delivers reliably, often exceeding expectations. His focus on quality helped us scale to 100,000+ users while keeping the product delightful and stable."
