MARK STRACHAN

Systems Architect for XR, Robotics & AI Simulation

I work across spatial computing, robotics, simulation, and perception — building systems that stay stable when timing, data, and interaction all have to align. My focus is on reliability: making complex environments behave predictably, even under extreme constraints.

With 25+ years experience across XR platforms, robotics, simulation, enterprise architecture, and regulated medical systems, I design the technical foundations that let machines, interfaces, and people operate together with precision.

Architectural Focus

Real‑time Engines & Simulation — scheduling, memory layout, and data‑oriented design for deterministic execution and high‑performance interaction.
Perception & Interaction Pipelines — computer vision for images and video, on‑device neural inference, and multimodal input systems.
Distributed Systems & Cloud Infrastructure — Kubernetes‑orchestrated services, gRPC, protobuf/MessagePack, caching, federation, and storage.
Multi‑user XR & Telepresence Systems — synchronized state, low‑latency communication, and collaborative environments for training and remote operation.

Systems I Build

My work sits where XR, AI, and robotics converge — where real‑time performance, determinism, and cross‑domain integration all matter at once.

These systems support spatial computing, high speed data streaming and caching, and cloud‑scale infrastructure.

Real‑time XR and robotics simulation engines for telepresence, surgical training, and manipulation.
Perception pipelines combining segmentation, smoothing, tracking, and neural inference for spatial understanding.
Distributed cloud architecture with multi‑VM NoSQL nodes, Kubernetes services, and efficient state synchronization across edge and cloud.
High‑performance rendering & interaction layers using compute shaders, procedural mesh instancing, ECS‑based collider systems, and Burst‑optimized math pipelines.
Spatial computing interface design, including MusicShaper — an 85,000‑line XR environment grounded in geometric music theory and backed by multiple granted patents and NSF SBIR awards.
