What I'm looking for

I’m looking for a role where I can support executives with calendar, communication, and confidential documentation—while using data accuracy and quality checks to improve reporting. I want a team that values efficiency, follow-through, and continuous improvement.

I’m building a career at the intersection of operations and information systems, with a Bachelors Degree in Computer Science that includes Information Systems, business analysis, and software engineering.

As an Executive Assistant at PBM Construction, I manage executive communication, diaries, meetings, minutes, and travel logistics—while keeping contract documentation and records accurate. I also administer budgets for senior executives, collaborate on weekly and monthly departmental budgets, and helped establish a culture of cost savings by 40%.

I bring strong data discipline from my work as a Data Entry Clerk at USAID Malawi, where I entered and validated program data with up to 98% accuracy, reduced discrepancies by 25%, and improved reporting reliability. I use tools like KoboToolbox, perform quality assurance checks, and conduct field data collection to strengthen on-time and consistent reporting.
