Founder of Rufus Engineering

I build high-performance engineering software used in real infrastructure and building projects.
My work combines structural engineering rigor, computational geometry, BIM interoperability and AI-driven automation.

I design hybrid systems where engineering truth shapes software architecture.
Clear logic, reliable automation, no black boxes.

• Computational modeling & data structures
• Geometry pipelines & custom 3D visualization
• Analytical ↔ physical model consistency
• BIM interoperability (SAF/JSAF, Tekla, Robot)
• AI-assisted workflows & multi-agent automation
• Modern .NET/WPF architectures (MVVM, DDD)

15+ years in structural engineering (bridges, viaducts, deep foundations, RC & steel)
10+ years building engineering applications:

• Analytical models
• Soil/stratigraphy modeling
• Reinforcement & design workflows
• Model versioning & geometry audits
• Robot, Tekla, and SAF/JSAF integrations
• Applied AI for structural model evolution

Platform for structural & BIM workflows: model synchronization, geometry validation, SAF/JSAF automation, Robot↔Tekla integration.

Enterprise toolkit for structural and geotechnical design: modeling, loads, reinforcement, visualization, workflow automation.

AI-powered development orchestrator: semantic/episodic memory, agent workflows, GitHub Actions automation.

Framework for analyzing, comparing, and versioning triangulated meshes and structural models.
Multi-level diffs, ML-ready data, semantic memory.

High-performance 3D engine for engineering visualization: solids, meshes, heatmaps, sections.
