- Filed and reproduced 70+ engine bug reports from customer projects, feeding verified fixes back into Unity releases.
- Contribute C++ and C# fixes directly to the Unity engine source, including a GPU memory-leak fix in the Profiler, Asset Database GUID-search tooling, and configurable worker-thread counts for containerized CI environments.
- Root-caused an eight-year-old engine race condition (ARM instruction reordering) that froze roughly 1.2 million sessions per month for a top-grossing mobile title — engine fix landed eight weeks after the first report.
- Delivered an emergency workaround and fast engine patch for a AAA studio's launch-blocking crash in a containerized build environment, days before their soft launch.
- Selected as Named Support Engineer for two of the world's top-grossing mobile game studios, serving as the technical bridge between customers and engine R&D.
- Represented the Engine Support team in customer meetings at GDC 2025.
- Promoted twice (Junior → Mid-level → Senior) while consistently ranking among the top-performing support engineers and maintaining high customer-satisfaction ratings.
- Credited in shipped titles Cities: Skylines II and V Rising for Unity engine and console support.
- Author knowledge-base articles and internal documentation that improve team efficiency and case resolution times.

“Sergio really went above and beyond, worked extra hours and provided very detailed, quality answers regularly to the customer. The customer was facing random crashes in a containerized environment eight days before their soft launch — we provided an immediate workaround, a very fast patch from Sergio, and a fix to the engine.”
Launch-blocking escalation for a AAA publisher
“Thanks so much for being on top of this ticket. Best collaboration ever.”
“Incredible work! This is an amazing success story and testament to your abilities and willingness to go deep into the investigation for both of these customers.”
Root-causing an eight-year-old engine race condition that froze millions of sessions per month for two of the world's top-grossing mobile games
“Sergio did a fantastic job of representing the Engine Support team, getting into the technical details and truly showing his passion for Unity to all of our customers.”
GDC 2025 customer meetings
“Outstanding job — nothing but fantastic feedback from the studio. This ticket was crucial, as it was preventing the team from delivering a new build to investors. They managed to deliver on time, which was vital for securing ongoing funding.”
Urgent networking escalation for an online-world studio
“Amazing work researching their issue and systematically going through the possibilities — he was even off ill while working through the ticket, but because of the urgency of the request, pushed on through.”
Urgent escalation for a global engineering & technology company
