About Me
An overview of my background and expertise as a developer.
I'm Haytsam Adzka Mawla, a Senior TypeScript Developer with extensive experience in both frontend and backend development. My primary expertise lies in building scalable applications using technologies such as React, Next.js, and Tailwind on the frontend, and Express.js, Laravel, and Filament on the backend.
I have contributed significantly to the banking and financial sector, developing systems that support critical business operations. These include loan and deposit analysis platforms, enterprise document archiving applications, and IT support ticketing systems. My focus is on creating reliable, secure, and efficient solutions that directly support organizational goals.
Beyond my core role, I also design and deliver freelance projects such as cooperative loan management systems and SaaS-based platforms like a WhatsApp API service. These experiences have strengthened my ability to translate business requirements into scalable and maintainable technology solutions.
I approach every project with a focus on clean architecture, maintainability, and long-term value. My goal is not just to deliver software, but to create solutions that enhance efficiency, improve security, and enable sustainable growth for the organizations I work with.
