Experience
Software Engineer
Apr 2023 — Present · Nashua, NH, US
Currently working with the R&D team, responsible for feature development, identifying root causes, and implementing solutions for critical customer escalations.• Identified the root cause of the SCTP association failure between the eNodeB and the Control Plane Aggregator, which caused all handovers to fail at the customer location. Implemented a fix that significantly improved the handover KPI.• Determined the main issue preventing the eNodeB from receiving the required 4 Component Carrier Aggregation (4CC CA) combination in the UE Capability Information. After implementing the fix, the UE achieved enhanced throughput.• Integrated the X2 interface between eNodeB and gNodeB via Control Plane Aggregator for Non-Standalone mode.• Played a key role on a cross-functional agile team during the feature development of multiple 5G NSA messages.• Upgraded the ASN grammar for the RRC, X2AP, and S1AP layers from 3GPP Release 12 to Release 16. Responsible for enhancing existing unit test cases, developing new test cases, and validating them on an end-to-end setup.• Upgraded the UE attach sequence as per 3GPP, ensuring the UE Capability Enquiry and UE Capability Info Indication occur after AS Security. Modified and enhanced unit test cases to validate the updated attach sequence.• Designed a framework to simulate incoming 5G messages, reducing dependency on 5G for 4G feature development.• Developed MAC layer unit test cases for both TDD and FDD to test various scenarios. • Optimized the CI/CD framework design, reducing runtime by 5 minutes.
