What I'm looking for

I seek roles combining telecommunications engineering and data analysis where I can build analytics systems, improve network performance, and collaborate cross-functionally to deliver measurable impact.

I am an electrical engineer specialized in telecommunications with experience applying engineering principles to data analysis and systems optimization. I combine technical knowledge of RF, fiber optics, and signal processing with hands-on data work to solve complex operational problems.

Over 1.5 years I have delivered analytics systems, engineered databases, and created data-handling protocols that improved workflows and supported long-term customer retention. I have also contributed to AI projects through precise data annotation and quality assurance using tools like Labelbox.

I work well with cross-functional teams, translating stakeholder requirements into clear reports and visualizations, and I focus on rapid concept development, execution, and measurable improvements in system performance and user experience.
