Initializing portfolio...
Passionate about building innovative web and mobile applications and leveraging data science to solve real-world problems. Specializing in full-stack development with Python, PHP, Flutter, and modern frameworks.
Software developer with 2+ years of experience building data-driven applications
I'm a software developer with expertise in designing, developing, and maintaining data-driven web applications using Python, PHP, and relational database systems. My experience spans full-stack development, database optimization, and implementing secure authentication systems.
I recently completed my Bachelor's Degree in Data Science at Eastern Africa Statistical Training Centre (EASTC), where I combined academic knowledge with practical experience from various client projects and field training at the National Health Insurance Fund (NHIF).
I'm passionate about advancing health information systems and contributing to initiatives that support Tanzania's development goals. My strong analytical skills and ability to work in Agile environments make me an effective collaborator and problem-solver.
