Summary
👤
Senior🎓
Top SchoolJohn Stewien is a seasoned software and hardware engineer with roots in electronics and over two decades of hands-on experience in C#, C++ and systems engineering, now based in Adelaide. He designs and re-architects high-performance simulation, visualization and data systems—from globe-scale terrain servers and RF/weaponry simulators to CUDA-accelerated swarm navigation—often turning prototypes into production-grade microservices and tooling. As Director and Principal Engineer at Cheesy Design he blends customer-facing systems analysis with recruitment and business ops, while his current role researching temporal and spatial step-function hardware combines reverse engineering, diagnostics and bespoke high-tech manufacturing access. Known for squeezing large performance gains out of legacy stacks (tenfold improvements on CUDA/C++ work), he also has deep experience tuning petabyte-scale PostgreSQL deployments and low-latency services. His goal to build a company that treats employees well and nurtures lasting customer relationships reflects a rare combination of technical depth and humane leadership. An early hardware background and long track record of shipping mission-critical systems means he excels where physics, visualization and scalable software intersect.
