RF Optimization Lead / Technical Lead at QuadGen — A MasTec Company (2015-11 – 2025-09)

Served as Technical Lead for 9 years on multi-market LTE and 5G NR RAN optimization and commissioning programs for AT&T and T-Mobile; provided guidelines on design, planning, capacity management, and deployment of GSM, UMTS, LTE, and 5G NR networks for field markets — directly matching T-Mobile's Sr Systems Design Engineer responsibilities.

• Developed and maintained regional standards, documents, processes, and practices covering RF engineering topics including parameter design, feature activation, neighbor list management, PCI/RSI planning, interference mitigation, and coverage optimization; distributed as reference for regions and markets.
• Conducted and managed design reviews and operations reviews with all markets in the region; owned KPI acceptance gate sign-off across planning, operations, design, and field teams for multi-market LTE and 5G NR program deliveries.
• Interpreted technical specifications in accordance with 3GPP, ITUT, IETF, and ANSI wireless industry standards to establish network designs and provide technical leadership for LTE/5G NR architecture, protocols, and future technology roadmap planning.
• Led Ericsson platform operations: OSS/ENM/CLI (AMOS/MOSHELL) parameter audits, feature activation campaigns, ICSU/GPEH/UEH/UETR/CTR trace analysis across multiple Ericsson releases; managed VoLTE optimization including SIP messaging validation and Ericsson advanced feature implementation.
• Performed 5G NR designs for multi-market regions: ENDC, NSA/SA architecture validation, Massive MIMO and beamforming parameter optimization, mm-Wave integration, carrier aggregation, RAN slicing, and UL/DL decoupling across 850 MHz, Sub-6, and mm-Wave spectrum bands.
• Executed deep Layer 3 (RRC/NAS) call flow analysis for 4G and 5G NR using Actix Analyzer, TEMS Investigation, and Quantum; diagnosed and resolved dropped calls, setup failures, HO failures, PCI confusion/collision, TNOL, and throughput degradation; drove consistency across planning tools and addressed data integrity issues across planning and deployment databases.
• Utilized MapInfo, Actix, and ASSET to implement Ericsson EDOS tools; developed Excel macros and SQL scripts for RAN reporting, KPI extraction, parameter audit automation, NL validation, PIM analysis, and pre/post-performance comparison.
• Managed Nokia/ALU multi-vendor RAN environment (T-Mobile NSN): CM Editor, BTS Site Manager, Magenta-Built; evaluated Nokia and ALU product lines, inter-operability, and small cell integration alongside Ericsson programs.
• Supported CBRS, LAA, IoT, DAS, and small cell implementations; evaluated new hardware and software releases for performance enhancement opportunities; provided technical leadership for new technology market launch activities.

RF Engineer III at Kineticom Inc. — T-Mobile (Nokia/NSN) (2013-09 – 2015-10)

Executed LTE/UMTS RF optimization and VoLTE deployment for T-Mobile Austin, San Antonio, and Corpus Christi markets; led cluster acceptance KPI delivery and single-site verification for new network additions.

• Led VoLTE deployment and DCR monitoring for Austin market; added LTE 2nd carrier, improved accessibility KPIs, MIMO utilization, call drop rate, and throughput to carrier acceptance thresholds.
• Performed golden parameter implementation, Layer 3 analysis, IRAT handover testing, PCI/RSI planning, cell-range planning, and IFHO cleanup; executed daily/weekly KPI analysis across CS and PS accessibility, retainability, and mobility metrics.

RF Engineer II at MobileComm Professionals Inc. — AT&T (Ericsson) (2012-01 – 2013-09)

Performed drive test analysis, post-processing (Actix/TEMS), and RF optimization across AT&T Ericsson macro network; troubleshot RRC setup failures, HO failures, idle mode issues, and 3G parameter discrepancies following BTS/BSC rehoming and LAC modifications.

• Conducted large-area neighbor list audits using MapInfo and Actix; implemented frequency changes, re-orientations, power adjustments, and tilt modifications based on systematic KPI analysis.

RF Engineer at MobileComm Professionals Inc. (2011-04 – 2012-01)

Conducted LOS surveys and feasibility analysis for microwave backhaul links; path profile analysis, Fresnel zone clearance calculations, antenna azimuth/height determination; prepared structured LOS survey reports and QC documentation.
