AVAILABLE FOR SELECT B2B ENGAGEMENTS
Senior cellular RAN, modem, and IoT software expertise for the failure modes that resist ordinary diagnosis—from baseband crashes to modem-integration instability.
MSA / FIELD NOTE 01
Trace-driven root cause, not assumptions.
01/ SERVICES
Fixed-scope diagnostic work, senior specialist subcontracting, and technical escalation support for teams that need a clear way forward—not a broad, undefined consulting mandate.
01 / MSAFor difficult crashes, signalling failures, regressions, and feature instability. Trace evidence, feature logic, source-level investigation, and test design converge on a credible route to resolution.
ROOT-CAUSE REPORT · INSTRUMENTATION PLAN · REPRODUCIBLE TEST PATH
02 / MSAFor embedded teams facing unstable attach, wake-up, PSM/eDRX, data-session, or field-behavior issues. Review the system from MCU middleware to modem behaviour and network traces.
INTEGRATION HEALTH CHECK · FAULT-ISOLATION PLAN · RELEASE TEST MATRIX
03 / MSAFor device programmes approaching certification, operator trials, or complex multi-vendor integration. Identify readiness gaps, clarify failure evidence, and enter formal test cycles prepared.
READINESS REVIEW · LOG TRIAGE · STANDARDS-ALIGNED ACTION PLAN02/ EVIDENCE
C-module crash analysis, trace instrumentation, root-cause explanation, feature-design support, and review-ready change contributions.
STM32, Quectel and Qualcomm platforms, AT/QMI interfaces, low-power LTE features, SSL, QXDM, and automated validation.
A career built across RAN optimization, modem IOT, GCF testing, device approval, customer escalation, and R&D delivery.
03/ TECHNICAL RANGE
The value is not a list of technologies. It is the ability to follow an issue from a network symptom through protocol behavior and modem logs to a testable software action.

04/ EXPERIENCE
A cellular career spanning operator networks, global R&D, modem labs, embedded devices, and independent B2B delivery.
LTE/5G baseband software analysis, trace diagnostics, feature design support, and C-code contribution.
Cellular IoT middleware for STM32 and Quectel/Qualcomm platforms; LTE-M, NB-IoT, AT/QMI, PSM/eDRX and validation.
3G/LTE protocol analysis, modem conformance, UE–network interoperability, field/lab issue investigation, and customer escalation.
Operator optimization, terminal approval, LTE/HSPA analysis, chipset integration, team leadership, lab buildout, and client delivery.
