What I'm looking for

I am seeking roles where I can apply data annotation and IT support skills in AI or technology teams, with opportunities for impact and growth.

I am a Business Information Technology graduate with eight years of hands-on experience in data annotation, IT support, and systems administration. I have contributed to AI projects involving image segmentation, 3D annotation, and chatbot data preparation, helping advance autonomous systems and conversational AI.

My IT background includes roles at government and international organizations where I installed and maintained software for large user groups, led preventive maintenance teams, managed IT assets, and provided level-1 support during events. I have experience maintaining websites and debugging applications.

I hold certifications and training from recognized providers including Huawei, Microsoft, and Google-aligned basic digital skills training, and completed mobile programming training covering Java, JavaScript, HTML, CSS, C++, and Android. I consistently apply Microsoft Office, Excel-based inventory reporting, and R for data analysis in research contexts.

I am detail-oriented, comfortable in remote and in-person technical roles, and committed to supporting AI development through accurate data annotation and reliable IT operations. I focus on delivering quality, scalability, and measurable improvements in operational output.
