The engineer studios call when multiplayer is broken before ship.
25 years, 13+ shipped titles. I fix the Unreal problems that are hard to hire for on a deadline — custom netcode, console bring-up, and pre-launch stabilization. Most recently: a P2P NAT-traversal NetDriver for Path of Titans live across all 10 platforms, with a projected ~$100K/yr relay bill turned usage-based.
You've got a deadline and a problem you can't staff for.
Multiplayer that desyncs or won't let players connect. A console port stuck in cert. A crash spiking in production three weeks before launch. These aren't "post a job req and wait two months" problems — they're "who can start Monday and actually knows this" problems. That's the call I take.
Multiplayer & Netcode
Netcode architecture, rescue, and hardening. NAT traversal / P2P, listen + dedicated server, replication, connection state machines, STUN/TURN/ICE relay-cost reduction, session & matchmaking flow.
"Built the P2P NAT-traversal NetDriver for Path of Titans across all 10 platforms; cut a ~$100K/yr relay bill to usage-based."
Console / Platform Bring-Up
Getting UE games running and certifying on PS5 / PS4 / Switch / Xbox — networking, platform SDK integration, native-lib porting, and the deploy plumbing to ship it.
"Ported libjuice to PS5, PS4, and Switch; stood up ICE transport on every current console with a custom Docker deploy."
Stabilization Sprint
A time-boxed pass on the crashes, perf, and memory bugs blocking your ship date. Vulkan/GC lifetime issues, platform-specific crashes, save-data migration, regression gating.
"Fixed an Android Vulkan crash hitting ~20K users, plus GC/Vulkan lifetime guards and a respawn-loop save-migration bug."
AI Dev Tooling for Studios
Build your team's internal AI tooling — automated code review, crash triage & dedupe, ticket cleanup, build/release automation, agentic workflows wired into your pipeline.
"Built an AI code-review bot, a Sentry crash digest, and a Jira deduper that cleaned 7.3K tickets."

Start small. De-risk every step.
Diagnostic call
Free 20 min. Tell me what's on fire — I'll tell you what's likely wrong and whether I'm the right fix.
Paid diagnostic
1–3 days, flat fee. I dig in and deliver written findings + a concrete plan. Low-risk yes.
Fixed-scope fix
The real engagement, with clear exit criteria. You know the price and the finish line up front.
Retainer
If it goes well, keep me on call — a set number of days a month for whatever comes next.
Prices up front. Scope is what we negotiate.
No discovery-call runaround to find out whether you can afford me. These are real working ranges for contract and work-for-hire engagements. Where you land inside a range depends on depth, deadline pressure, and what shape the codebase is in — which is what the first call is for.
