High-Performance Networking
I help telecom and technology companies build fast, reliable network data paths — the same kind of high-throughput traffic handling used in modern mobile networks, tested from first packets on the wire to multi-lane hardware steering at 10 Gbps and beyond.
Mobile & Telecom
Modern 4G and 5G networks move enormous volumes of subscriber traffic through the user plane — at the network edge, in the core, and inside virtualized services on standard servers. Every millisecond and every CPU cycle counts.
Mobile user-plane workloads — tunneling, encryption, quality-of-service marking, inspection, and forwarding at gateways and routers — must sustain millions of packets per second with predictable latency. A traditional operating-system networking stack adds overhead that makes consistent high-speed processing difficult on commodity hardware.
Specialized high-performance networking bypasses the usual bottlenecks and talks to network cards directly from application space. It is widely used in cloud and virtualized telco deployments for high-throughput user-plane functions, load balancers, session controllers, and edge gateways where packets must be received, classified, and forwarded without unnecessary per-packet delay.
The open-source tools and tutorials I have built map directly to problems telecom engineers face when bringing up, validating, and scaling user-plane software on real hardware.
Services
Practical networking work — not slide decks. I ship code, measure on real hardware, and leave your team with something maintainable.
Custom traffic-handling applications: receive and transmit pipelines, multi-core workers, memory pools, and efficient producer/consumer designs.
Throughput and latency tuning — batch sizes, queue depth, memory placement, cache-friendly packet handling, and network card statistics analysis.
Program network cards to redirect, drop, or steer traffic in hardware. Validate rules on your target hardware before production.
Traffic generators, capture tools, and lab harnesses to stress-test your stack at full speed with measurable, repeatable results.
Software policy lists, traffic distribution across cores, hardware-assisted packet parsing, and hybrid designs that minimize CPU per packet.
Code reviews, team onboarding, monitoring integration, and split designs for separating control logic from traffic handling.
Technical depth
My work spans the full high-performance networking stack — environment setup, device configuration, packet lifecycle management, and driver-specific behavior on production hardware.
Portfolio
A growing body of production-style examples — each demonstrates a specific networking capability with runnable code and documented test commands.
~10 Gbps on Intel XL710 with hardware checksum offload — validated in the lab.
Match rules for queue redirect and in-card drop, validated with network statistics.
Multi-lane receive pipelines with per-core workers and hash distribution.
Address and port-based packet classification for policy enforcement at speed.
Custom monitoring callbacks and multi-lane traffic capture at high data rates.
Primary and secondary processes sharing packet work via efficient ring buffers.

How we work
Understand your throughput targets, network hardware, latency budget, and existing stack.
Stand up a lab environment, configure network cards, and prove the critical path on real traffic.
Use network statistics, per-lane counters, and controlled generators to quantify behavior.
Hand off documented code, build instructions, and knowledge your team can extend.
