What I'm looking for

I seek an entry-level data role where I can apply Excel and SQL skills, build dashboards, learn advanced analytics, and grow within a collaborative, data-driven team, and also an AI research and AI trainer.

I am a detail-oriented Junior Data Analyst with hands-on experience preparing dashboards, cleaning and validating datasets, and extracting data using SQL fundamentals. I have created Excel dashboards with Pivot Tables and charts, documented reporting processes, and communicated insights to both technical and non-technical stakeholders.

My background includes a B.Eng. in Computer Engineering (Second Class Upper) and completion of the IBM Data Analysis Professional Certificate. I am comfortable working remotely, have experience training beginners in Python and Excel, and am eager to grow within a data-driven organization.
