SOC 2 Audit Chains for ML Pipelines: A Security Deep Dive
How we built tamper-evident audit logging with Ed25519 digital signatures, etag-based optimistic concurrency, and FIPS 180-4 SHA-256 integrity hashing into every pipeline stage. A detailed look at SOC 2 CC8.1 controls in an ML platform.

Why Your Seismic Interpretation Needs an Audit Chain
Cryptographic hash chains, Ed25519 digital signatures, and tamper-evident logging for subsurface decisions. How we built SOC 2 Type II audit controls into the interpretation pipeline itself.

3D U-Net Denoising: From Research to Production ONNX
The journey from Ronneberger 2015 to a production ONNX model running on Azure AKS. We cover architecture decisions, INT8 quantization (Jacob 2018), MC Dropout uncertainty, and streaming volume processing for 50GB+ surveys.
Dr. James Okonkwo
The Case for API-First Seismic Interpretation
Why the future of subsurface intelligence is programmable. OSDU R4 integration, RESTful pipeline orchestration, and why the best seismic interpretation tool is the one that fits into your existing data ecosystem.
David Park
Circuit Breakers, Outbox Patterns, and the SRE of Seismic
Applying Nygard, Hohpe & Woolf, and Google SRE principles to seismic data processing. How we use transactional outbox, circuit breakers with SPC health scoring, and error budgets to keep pipelines running at 99.9% uptime.
Marcus Andersen
Uncertainty Quantification with MC Dropout for 3D Volumes
Implementing Gal & Ghahramani 2016 for production seismic interpretation. We cover Dropout3d placement, Welford online variance, convergence diagnostics with R-hat (Gelman-Rubin 1992), and how uncertainty maps guide human-in-the-loop review.
