Network Security & Applied AI

Thirty years of pager scars

Keep the lights on, the amps hot, and the packets flowing.

I design resilient routing, DDoS response programs, and private AI workflows for teams who can’t afford chaos. Every playbook comes from decades of carrying the pager for carriers, clouds, and large-scale events.

Built early ISPs, ran global DDoS defense, still chasing the perfect route.

Tier 1 builds shipped

Carrier and national backbone programs architected end-to-end.

Signature Wins

From bootstrapping ISPs in the dial-up era to steering cloud-scale automation, I turn infrastructure chaos into predictable, measurable performance. Here’s how that journey translates into value today.

Carrier-Grade

Building Networks That Don’t Flinch

Architected national ISP backbones across Canada and Ireland, evolving them from scrappy dial-up to high-availability broadband for millions of subscribers.

Threat Intel

DDoS Response for the Global Internet

Led Tata Communications’ worldwide mitigation strategy, creating playbooks that shielded Tier-1 carriers and Fortune 100 brands from record-breaking attacks.

Founder DNA

Mimir Networks

Founded Mimir Networks to give defenders predictive visibility into multi-vector attacks—automating countermeasures years before “SOAR” became a buzzword.

Cloud Scale

Oracle Cloud Infrastructure

Served as consulting engineer shaping OCI’s edge security, blending telemetry, AI/ML and BGP expertise to keep hyperscale services resilient.

Experience & Backstory

Every stage sharpened a different weapon: carrier routing, operations in crises, executive leadership and now AI-enabled automation. That breadth is what keeps today’s hybrid environments honest.

Today

Independent Principal Architect & Advisor

Partnering with service providers, governments and scale-ups to modernize peering, automate threat response and turn AI aspirations into audited pipelines.

Oracle Cloud Infrastructure

Consulting Engineer, Edge & Security

Designed adaptive defenses for OCI’s backbone— marrying streaming telemetry with reinforcement learning for near-real-time traffic decisions.

Mimir Networks

Founder & CEO

Took the company from whiteboard to production platform, delivering predictive DDoS analytics that inspired Tier-1 carriers and critical infrastructure teams to modernize their playbooks.

Tata Communications

Global DDoS & Security Engineering Lead

Orchestrated follow-the-sun response across Tata Communications’ footprint in 190+ countries and territories, aligning carriers, finance and public-sector operators behind a single playbook.

Avici Systems

Principal Consulting Engineer, Core Routing

Partnered with the world’s largest carriers to deploy Avici’s terabit routers, translating bleeding-edge silicon into reliable customer architectures.

Early ISP Pioneer

Canada & Ireland

Launched some of the first ISPs on both sides of the Atlantic, scaling dial-up POPs into resilient broadband networks with 24/7 NOC discipline.

Patents & Research

Filed and pending work that captures where networking, AI and security converge. Each patent draws on hard-earned operations lessons and the need for automation you can trust.

US 2025

Dynamic Time Slice Autoencoder Network Anomaly Detection

Autoencoders segment router telemetry into adaptive time slices, spotting stealthy changes before they collapse service quality.

US20250280034A1 WO2025184181A9
US 2025

Congestion Control in RDMA Fabrics

Feedback-driven control plane that balances ultra-low latency workloads with fairness, co-authored with the Oracle engineering team.

US20250168122A1

Stages, Briefings & Workshops

Trusted to brief audiences—from red-team summits to Interpol leadership—on what really happens when continents’ worth of traffic shift in an instant.

Security Conferences

  • CanSecWest  / EUSecWest — Carrier-grade DDoS war stories and Europe’s sister program on AI-enhanced threat hunting.
  • SecTor (Toronto) — Live-fire demos on turning post-incident chaos into repeatable runbooks.
  • AtlSecCon (Halifax) — Regional keynote on fusing ISP-grade visibility with incident command for Atlantic Canada.

Industry & Agency Briefings

  • INTERPOL Cybercrime Directors Assembly — Shared frameworks for cross-border takedowns and ISP coordination.
  • NANOG 35 – Underhanded Peering Tactics — Guided operators through BGP hygiene, flow telemetry and automation pitfalls.
  • Canadian ISP Summit (CIRA) — Led sessions on protecting national backbones and cooperative incident response.
  • FIRST & CERT Communities — Facilitated workshops on incident command for multi-tenant clouds.

Why Teams Call Me

Jim DeLeskie

Jim DeLeskie

I’m equal parts builder and operator. I thrive on messy environments—where you have to honor decades of networking fundamentals while adopting AI fast enough to matter. When the alarms light up, my job is to keep everyone calm, communicate clearly and get the packets flowing.

My ethos is simple: discipline from veteran service, curiosity from a lifetime in music, and an obsession with sharing knowledge so the next generation is battle-ready.

Operator Empathy

I’ve manned NOCs, cleared BGP storms at 3 a.m. and negotiated peering in the hallway between sessions. That empathy keeps recommendations grounded.

Leadership Under Pressure

Veteran mindset: assess, prioritize, execute, debrief—and like a good setlist, make sure every handoff hits the right note before the encore.

AI with Guardrails

AI is a force multiplier—when the data is clean, the models are explainable and the humans are still in the loop. I tune the stack like vintage tube amps: loud, clear and never blowing out your speakers.

Latest Writing

Long-form reflections, field notes and playbooks for operators who balance uptime, security and team sanity.
