About
My name is Riak Mawut Angui Atem. I hold a Bachelor of Business Administration (BBA) in Accounting from Ndejje University, Uganda. I am a results-driven Finance and Logistics professional with over two and a half years of progressive experience supporting humanitarian health programmes in South Sudan. I demonstrate proven expertise in end-to-end financial management, procurement cycle administration, supply chain coordination, and inventory control within donor-funded and NGO operational environments.
Throughout my career, I have developed exceptional proficiency in upholding strict accountability standards, donor compliance frameworks, and audit-ready documentation practices. I am skilled in deploying QuickBooks, ERPs, and advanced Excel-based systems to drive operational efficiency and transparent reporting. My experience spans financial documentation, accounts payable/receivable processing, invoice verification, bank reconciliation, and comprehensive expenditure tracking.
Currently in my 4th year pursuing a Bachelor's degree in Cybersecurity at the University of Juba, where I have developed practical coding skills and expertise in secure systems design. Through my studies and independent practice, I design and build fully responsive websites and web applications using modern frameworks like Next.js, React, and MongoDB. My web development work emphasizes accessibility, mobile-first design, secure defaults, clean architecture, and cost-effective deployment strategies.
I am recognized for meticulous attention to detail, sound judgment under pressure, and the ability to collaborate effectively within multidisciplinary humanitarian teams. Professionally, I am detail-oriented, analytical, accountability-driven, and committed to leveraging financial acumen, logistics expertise, and technical skills to strengthen programme delivery. I offer affordable freelance services for web development and technical solutions for small businesses and personal projects.
