// Technical Ledger
A technical ledger, not a marketing blog. Original research, architecture investigations, and engineering findings.
Passive intelligence gathering via OT telemetry reveals critical blind spots in Industrial Control Systems. This paper investigates how boiler sensor data and PLC communications can be intercepted and thermodynamically modeled by adversaries, and proposes countermeasures for securing operational technology environments against stealthy reconnaissance.
Dynamic Application Security Testing integrated at scale within CI/CD pipelines. We analyze automated vulnerability scanning, exploit payload generation, and full vulnerability lifecycle management, from discovery through triage to remediation, in production-grade DevSecOps pipelines.
Mixture of Prediction Experts (MoPE) middleware that intercepts LLM API requests and dynamically routes them to the optimal model tier based on quantile regression over request complexity, reducing token consumption and API costs by up to 60% across Gemini and GPT workloads without measurable quality degradation.
