Cybersecurity & Resilience
Moving beyond generic compliance check-boxes to engineer concrete defensive controls, resilient host architectures, and empirical detection capabilities.
Security Architecture
Zero-trust topology, cryptographic segmentation, and perimeter defense validation.
Detection Engineering
Custom rule development (Wazuh, Sigma, Suricata) and telemetry pipeline tuning.
Host & Kernel Hardening
Linux kernel parameters, CIS benchmark enforcement, and container runtime guards.
Incident Readiness
Automated isolation playbooks, forensic readiness, and log integrity assurance.
DevSecOps & Cloud Architecture
Engineering deterministic, immutable cloud infrastructure using Terraform, automated CI/CD security controls, and strict IAM governance across AWS, Azure, and GCP.
Infrastructure as Code
Modular, DRY Terraform modules with strict state locking and automated drift detection.
CI/CD Pipeline Security
Static analysis, dependency auditing, secret scanning, and signed artifact provenance.
Cloud Cost Rationalisation
Empirical right-sizing, storage tier pruning, and architecture-level waste elimination.
Container & Mesh Security
Distroless base images, read-only root filesystems, and eBPF/Tailscale routing.
Artificial Intelligence Engineering
Building production-ready AI applications, retrieval-augmented generation (RAG) architectures, model integration controls, and autonomous agent safety sandboxes.
RAG System Architecture
Hybrid vector indexing, chunking strategies, re-ranking pipelines, and citation validation.
Agent Workflow Engineering
Deterministic tool execution, error-recovery loops, and automated workflow orchestrations.
AI Security & Risk Controls
Prompt injection mitigation, data exfiltration guards, and model privilege boundaries.
Proof-of-Concept Development
Rapid functional prototypes proving algorithmic feasibility before enterprise budget allocation.
Technical Validation & Feasibility
Independent engineering due diligence that tests whether a proposed solution or vendor claim can withstand production latency, security constraints, and scale.
Architecture Validation
Stress-testing topologies against concurrency spikes, failover scenarios, and data corruption.
Technology Evaluation
Rigorous, vendor-agnostic benchmark bake-offs between competing software stacks.
PoC Validation
Code inspection and load testing of third-party or internal prototypes prior to sign-off.
Feasibility Assessments
Determining if mathematical, API, or protocol limitations will block business intent.
Applied Technical Research
Active lab experimentation into emerging attack surfaces, automated defense tooling, low-overhead Linux telemetry, and open-source infrastructure patterns.
Three Layers. One Technology Ecosystem.
Independent capabilities engineered to separate executive direction, empirical validation, and continuous operations without consulting blur.
