- About

Engineering the invisible infrastructure.

Four years validating the radio access networks that carry billions of conversations and connections - every day, in every weather, across every band.

I spend my days in the messy, beautiful intersection of protocol stacks, real hardware, and customer expectations. RAN testing isn't about pass/fail - it's about understanding why a UE re-attaches at the cell edge at 3am, or why throughput dips during a specific handover sequence.

Currently at Parallel Wireless in the Radio R&D group, I design Robot Framework and Python automation for dual-band LTE and 5G stability - multi-UE throughput, attach/detach endurance, and RSRP-controlled long-run tests that catch issues humans wouldn't sit through.

Before that, four years at Mavenir Systems validating LTE and 5G SA / NSA for Deutsche Telekom, Virgin Media O2, and NEC - Carrier Aggregation up to 1.4 Gbps DL, ORAN CU/DU/RU integration, and root-cause analysis across the full protocol stack.

- Focus areas

Where I add leverage.

A few specific places I tend to move the needle - from automation that runs while the lab sleeps, to debug that catches the issue customers haven't reported yet.

01.
Automation Framework

Multi-UE stability & throughput

Robot Framework + Python keywords for dual-band LTE stability, simultaneous multi-UE TCP/UDP throughput, and KPI validation with RSRP-controlled baseline.
