What I'm looking for

I am looking for a senior RF role where I can apply 5G planning, data-driven optimization, and ML to improve network KPIs and user experience in a collaborative, innovation-focused team.

I am a Senior Radio Frequency engineer with deep experience in 5G and LTE network planning, drive-testing, and optimization across multiple vendors and markets. I combine academic research in machine learning for wireless systems with hands-on field experience delivering measurable KPI improvements.

My work includes leading RF optimization teams, designing network plans, conducting large-scale 5G data collection and benchmark testing, and developing automated KPI dashboards and ML models to predict throughput. I have a history of troubleshooting complex network issues using L3 signalling, carrier aggregation techniques, and vendor tools to improve coverage, capacity, and user experience.

I hold MSc degrees in Communication Systems and Telecommunication Engineering and have produced thesis work applying LSTM and Random Forest models for 5G throughput prediction and channel estimation research for Massive MIMO. I seek roles where I can apply RF expertise, data-driven optimization, and cross-vendor experience to drive network performance and innovation.
