Cloud Platforms (AWS & Azure)
Architecture reviews, migrations, and cost optimisation across AWS and Azure. Infrastructure as code, CI/CD pipelines, and platform engineering done by an engineer who runs production systems.
Identity & Access Management
Entra ID, PKI, and zero-trust access control — designed and hardened for organisations that can't afford a breach.
Networking & Infrastructure
Design, hardening, and ongoing management of on-prem and cloud network infrastructure — firewalls, VPNs, DNS, and production systems.
Services
PKI & Certificate Services
Internal certificate authorities, TLS certificate lifecycle management, and code/document signing — PKI designed and operated by an engineer who's built production PKI for defence-grade systems.
Email Security & Exchange
SPF, DKIM, and DMARC deployment and enforcement to stop spoofed mail from your own domain, plus Exchange Online migration and hardening.
Server & Systems Administration
Linux and Windows Server builds, hardening, patching, and day-to-day administration — properly run infrastructure without a full-time sysadmin on staff.

Wi-Fi and network troubleshooting, PC and laptop setup and repair, printer configuration, and general IT support for homes and small businesses in Sydney's Inner West. Book a session online.
AI Integration & Enablement
Practical AI adoption for businesses: LLM and agentic-workflow integration, automation of real processes, and coaching your team to use AI tooling effectively and safely.
DevOps Coaching
Hands-on uplift for engineering teams: CI/CD, GitHub Actions, testing discipline, release automation, and observability. Coaching embedded in your real codebase, not slideware.
Microsoft 365 Security Hardening
Entra ID, Intune, and Defender configured properly for small business: phishing-resistant MFA, conditional access, device compliance, and Essential Eight alignment.
On-Demand 3D Printing
Rapid prototyping and small-batch manufacturing in engineering materials — ASA, ABS, PETG, TPU. CAD design to functional part: enclosures, jigs, fixtures, and replacement components. Sydney turnaround.
Fractional CTO
Part-time technical leadership for startups and SMEs: architecture direction, build-vs-buy calls, hiring support, and a roadmap your engineers can actually execute.
Live, not a claim
We run the infrastructure we sell
A public, GPS/PPS-disciplined stratum-1 time service — NTS-secured, fully observable, built and operated by the same engineer who'd work on yours.
