Mobi Arf

I’m a Senior Software Engineer and Full Stack (MERN) Engineer with 7+ years designing, developing, and scaling high-performance SaaS platforms, enterprise applications, and cloud-native solutions. I specialize in React.js, Next.js, TypeScript, Node.js, Express.js, MongoDB, PostgreSQL, and AWS.

In my current role, I lead the architecture, development, and delivery of customer-facing SaaS applications. I improved platform performance by 35% to support continued growth, and I increased customer engagement by 25% through modern, responsive, accessible experiences.

I focus heavily on backend performance and reliability—designing and optimizing RESTful APIs and backend services to reduce query latency by 40%, and maintaining 99.9% uptime by deploying containerized applications on AWS (ECS/EC2/S3). I also implemented advanced state management with Redux Toolkit and Context API to enable real-time capabilities and better scalability.

I drive quality and delivery efficiency by streamlining CI/CD automation with GitHub Actions, Docker, and AWS—reducing release cycles by 40%—and building testing strategies with Jest, React Testing Library, and Supertest to reach 90%+ automated coverage. Across teams, I mentor engineers, lead code reviews, and contribute to system design, microservices, and event-driven architectures.
