Work experience

Senior Professional -I Engineer at Capgemini Engineering, May 2021 - Present · 5 yrs 4 mos, Hybrid, O1 / OAM Features (Jan 2025 – Present) Delivered multi-cell O1/OAM features by coordinating across development, testing, and product quality teams, enabling on-time release with zero major spillovers. Developed O1/OAM features from design to deployment, including implementation, Coverity analysis, and defect resolution, reducing static analysis issues by ~30–40% per release. Resolved critical O1/OAM production bugs through root-cause analysis and targeted fixes, improving system stability and operational reliability in live test environments. Acted as a technical bridge between feature teams, accelerating defect turnaround and minimizing cross-team dependency delays. Facilitate team-wide DevOps practices, establishing CI/CD pipelines and automated testing protocols for O1/OAM systems FlexRAN L1 Features (May 2021 – Jan 2025) Designed and implemented massive-MIMO beamforming algorithms (ZF, MMSE) for DL/UL channels, directly contributing to throughput and SINR improvements in FlexRAN systems. Enabled ORU-side beamforming (with and without beamweights) across CAT-A and CAT-B architectures, improving deployment flexibility for multiple radio configurations. Led end-to-end L1 bring-up, from BIOS validation through binary generation, supporting successful inter-team integration and multiple release cycles. Diagnosed and fixed critical L1 crashes using IQ extraction (PCAP), timing analysis, and spec-level debugging, reducing system crash recurrence in integration testing. Performed deep PHY analysis down to RE level using 3GPP specs (38.211, 38.214), accelerating root-cause identification for complex PHY issues. Proactively stabilized L1 features under tight schedules, contributing to higher first-pass test success rates during system validation.

Development Engineer at MBIT Wireless Pvt Ltd, Apr 2020 - Apr 2021 · 1 yr 1 mo, Chennai, Tamil Nadu, Working on Multipath RSTD estimation on LTE Positioning Reference Signal

Development Engineer at MBIT Wireless Pvt Ltd, May 2019 - Mar 2020 · 11 mos, Chennai Area, India, Worked and lead on algorithms like * Timing and frequency error estimation for CAT-M1 and CAT-M2 devices based on max-peak values obtained through CRS processing * Doppler estimation of CAT-M2 devices based on two methods, CIR and CFR methods * HARQ feature of LTE * CRS-IC feature of CAT-M2 devices * Signal power estimated through coherent combining, differential correlation methods * Noise estimations

Senior Assistant Professor at MADANAPALLE INSTITUTE OF TECHNOLOGY & SCIENCE, Jan 2018 - May 2019 · 1 yr 5 mos, Andra, India, Research: *Worked on modulation techniques related to 5G systems like spatial modulation and index modulation. *The objective of this project is to fabricate ASICs containing entire signal processing blocks of transmitter and receiver of an entire 5G wireless system which is a long term goal. *Our action was first to implement the entire 5G wireless system with optimized modulation techniques on a Software Defined Radios (SDRs) and then to fabricate ASICs once we attain good performance out of implemented system on SDRs. Academic Curriculum: *I have (a) administered for proper functioning of all laboratories, (b) developed laboratory facilities in the ECE department, (c) administered to prepare laboratory manuals with respect to the current research scenario, and (d) made budget proposals for improving the laboratory infrastructure, publication of journal articles/conference proceedings. *I have (a) organized short term training programs for the undergraduate students, (b) organized National level symposiums and workshops for undergraduate and graduate level students, and, (c) convened departmental faculty meetings for discussing about the academic and research curriculum. Taught courses on "Digital Communication Techniques", "Communication Systems", "Principles of Signals and Systems", and Laboratory classes like "Microwave Laboratory", and "Communication Systems".

Research Scholar at Indian Institute of Technology, Kharagpur, Jul 2012 - Oct 2017 · 5 yrs 4 mos, WestBengal, India, *Designed an entire 4G system, that is, transmitter, channel and receiver. *Transmitter side worked on: space-time coders, modulation schemes. *Receiver side worked on: equalizers, successive interference cancellation receivers, group decoders. *Channel side worked on the design and analysis of fading channels. *Have written algorithms on each of the above aspect of the system then analysed. *One such is tradeoff analysis of multiplexing oriented transmission schemes in MIMO systems. Tradeoff comes into picture when we have control over transmission power. By increasing the transmission power, we can either increase the communication transfer rate or increase the efficiency of the communications. *The MIMO algorithms handled can be best suited to practical systems like 4G systems. *Handled both mathematics and simulation in Matlab & C to perform the above projects. *The above works had fetched me Doctorate degree.
