Joan Mwaniki

I am a resourceful data annotator and data analyst with over four years of experience in data analysis, annotation, inventory management, and project coordination. I specialize in preparing high-quality labeled datasets for machine learning and refining processes that improve model performance.

I have hands-on experience analyzing and labeling images, text, audio, and video using tools like Superannotate, and I ensure consistency and accuracy through meticulous validation workflows. I collaborate effectively with data scientists and engineers to align annotation with project requirements and to provide actionable feedback.

As a project coordinator and procurement analyst, I managed inventory, prepared Bills of Quantities, handled requisitions and deliveries, and supported contractors on timelines and invoices. I used Power BI, Excel, and other visualization tools to produce reports for internal stakeholders and donor updates, improving decision-making.

I work well independently and in remote teams, leveraging CRM systems, communication tools such as Slack and Zoom, and AI tools like ChatGPT to increase productivity. I am motivated by clear objectives, quality standards, and opportunities to contribute to data-driven projects that scale.
