Data Analyst focused on SQL, Power BI, and quality-driven traceability.
KenyaWhat I'm looking for
I’m a Data Specialist and Quality Control specialist who optimizes data workflows, strengthens traceability, and ensures compliance with international food safety standards. I focus on accuracy and efficiency to drive continuous process improvements that support organizational goals.
In my current role, I revolutionized the GRN database management system—reducing entry errors by 90% and making the document the organization’s primary reliable database. I also designed and implemented spreadsheet-based templates and automated reporting workflows, cutting manual work and accelerating data processing.
I enhance batch-to-dispatch traceability so shipments are tracked and compliant with organizational KPIs, and I help secure timely supplier payments by ensuring GRNs are generated and verified within strict deadlines. In parallel, I’ve streamlined international shipment reporting by ensuring 100% timely reporting through stronger communication between the quality team and logistics.
My quality foundation is reinforced by maintaining HACCP and ISO standards and by investigating root causes of recurring quality issues to drive corrective action plans. Previously, as an Analytical Chemist Intern, I increased laboratory productivity by 30% through proactive equipment maintenance and supported rigorous chemical analyses using FTIR and HPLC while achieving a 90% safety compliance rating with a zero-incident environment.
