What I'm looking for

I’m looking for a role where I can deliver high-quality, guideline-adherent data for AI/ML training and support dependable IT operations. I value fast, remote teamwork, accuracy, confidentiality, and continuous improvement to drive better model performance.

I’m a detail-oriented Data Annotator and IT Professional with a strong technical background in information technology and data management. In my current role at RWS Group, I support Artificial Intelligence and Machine Learning projects by providing high-quality real-world inputs that shape how models learn and perform.

I prioritize accuracy and strict adherence to annotation guidelines, delivering validated, high-quality datasets. At The Jordan Hospital, I oversee network infrastructure, backups, website/enterprise software administration, and IT strategic planning to keep critical systems running smoothly.

Earlier, as an ICT Intern with Nyeri County Governor’s Office and as a Network Technician at Fresh Products, I handled troubleshooting, software/hardware maintenance, and secure LAN design. I bring a consistent focus on reliability, confidentiality, and continuous improvement across both AI data work and IT operations.
