About

Senior Software Engineer with over 6 years of experience in 4G/5G UE Layer-1 (Physical Layer) firmware development. Specialized contributions have been made to uplink transmission pipelines, TX hardware control, and real-time modem behavior optimization. Emphasis has consistently been placed on delivering low-latency, timing-accurate firmware while maintaining robustness and stability across multiple modem generations and real-world deployment scenarios. Close collaboration has been carried out with RF, hardware, MAC/RRC, and system integration teams to diagnose and resolve complex system-level issues. Core strengths include the design of clean, scalable Layer-1 control logic, with sustained focus on debuggability, maintainability, and simplification of timing-critical data flows without impacting performance.

Senior Engineer

Jul 2022 – Present · 3 yrs 9 mos · Bangalore Urban, Karnataka, India · On-site

Working as part of the UE Layer-1 Driver TX team across multiple MediaTek chipset generations (Gen97/98/99), responsible for uplink transmission processing and TX hardware control.
Designed and developed low-latency Layer-1 embedded firmware using real-time and concurrent programming techniques to meet strict modem and hardware timing constraints.
Conducted uplink timing tuning using Anite test setups, calculating hardware engine processing latencies for different uplink channels and programming TX hardware engines based on required processing timelines.
Debugged system-level modem issues by analyzing PHY logs, KPIs, and network traces, identifying root causes during new chipset bring-up, and providing software workaround solutions for hardware-related issues.
Supported customer and MTBF issues, delivering timely updates with detailed technical root-cause analysis in lab and field environments.
Possess a good understanding of LTE and 5G NR Physical Layer procedures, with hands-on experience referencing 3GPP 38.211, 38.212, and 38.213.
Collaborated closely with cross-functional teams including RF, MAC/RRC, and PHY, leveraging C/C++, Perforce, Jenkins, and UE/network log tools (R&S, Anritsu, Anite) to ensure stable and reliable uplink performance.
