4G/5G mobile-core and high-performance data-plane engineer with 20+ years building carrier-grade UPF, SMF, DPI, and eBPF/XDP packet processing for telecom operators, ISPs, MVNOs, and MNOs. What Sets Me Apart I deliver at team scale as a single engineer, using an AI-native, spec-driven development method backed by rigorous automated verification. You get fast, cost-effective delivery at carrier-grade quality. Flagship: 4G/5G User Plane Function (UPF) I engineered a carrier-grade 4G/5G UPF (~180K LOC): • eBPF/XDP data path with lock-free fast paths, ~100x per-core throughput (~10 Gbps/core), scaling to millions of concurrent sessions • DPI/SDF policy control with 400+ protocol classification, precedence-aware PDR management, and carrier-grade NAT • single-flow lookup, control-plane scaling, 5G feature support • built-in REST API and management GUI It deploys as a 5G SA UPF and as a 4G EPC PGW-U (CUPS), including 5G NSA. Alongside it I built a full verification toolchain, so delivery stays fast without sacrificing reliability: • 380+ automated tests with a CI gate • simulation suite (PFCP/SGW-C/U sims, GTP-U generator) • client-server UE-experience test system • IPFIX/IPDR collector and dashboard Core Technologies • Mobile core: 5G UPF, SMF, PGW, 4G EPC, CUPS, PFCP, GTP-C/U, SDF/PCC/PCRF, 5G SA/NSA • Data plane: eBPF, XDP, carrier-grade NAT, DPI, zero-copy packet processing • Networking: TCP/IP, IPv6, NAT, VPN, routing, SNMP, Netflow/IPFIX, VoIP/SIP • Security: NIDS/NIPS, IDS/IPS, transparent TLS/SSL inspection, AAA, RADIUS, 802.1X • Platforms & languages: Linux kernel, OpenWrt, Go, C, C++, Python; Prometheus, Grafana, REST/OpenAPI Key Project Experience 4G/5G Mobile Core & User Plane • XDP-accelerated SGW-U (Go + eBPF) interoperating with a 4G SGW-C over PFCP/Sxa, with in-kernel GTP-U forwarding (3GPP TS 29.244 / 29.281). • SMF control-plane enhancements: dynamic REST configuration, per-APN PCC rules, and IP-pool allocation for 4G/5G CUPS deployments. Security Gateways • Modular multi-VLAN NIDS/NIPS, inline gateway anti-virus, and transparent TLS/SSL inspection (HTTP/S, SMTP, FTP) for ISP and enterprise security gateways. • Full dual-stack IPv6 (NAT64/NAT66, DNS64, transparent proxy) on a high-performance XDP/eBPF data path. WLAN & Wireless • Enterprise/MSO WLAN platforms: RF management, IDS/IPS, VLAN, WIDS, and multi-vendor AP management. • AAA, RADIUS, LDAP/AD, and 802.1X access control; authored SNMP MIBs and integrated with operator OSS/BSS systems. Network Management & Automation • Universal NMS for SNMP-based IoT devices with plug-and-play onboarding, zero-touch provisioning, and auto-discovery. • Automated statistics, reporting, and real-time analytics with Prometheus, Grafana, Bash/Lua, and cloud integration. APIs & Web Interfaces • OpenAPI-compliant REST APIs and modern web GUIs for policy management and real-time analytics. Legacy & Hybrid Networking • Service Connection Manager (SCM) for Cisco 6400 UAC, and SNMP-based device discovery for large-scale enterprise and ISP/MVNO/MNO deployments. Why Choose Me • 20+ years turning high-level concepts into commercially viable, production-ready products. • AI-native delivery: team-scale output as one engineer, with automated testing keeping quality carrier-grade. • Proven leader and mentor of global teams (up to 40 engineers) across the USA, China, and India. • Clear communicator, strong at remote collaboration, requirements analysis, and client engagement. • Remote-first worldwide; reliable, long-term, and fully invested in your success.
