Engineering notes from the Quant team
Perspectives on cybersecurity, cloud, networking, AI, energy and software engineering — written by the engineers who deploy them.
Designing zero-trust networks for African enterprises
How we architect zero-trust segmentation across multi-site deployments — and why perimeter thinking no longer holds up.
Migrating from legacy PBX to cloud calling at scale
Lessons learned migrating 1,200+ users to a unified cloud PBX across 14 branches.
Hybrid solar systems for industrial campuses
Sizing, monitoring and ROI for hybrid solar deployments — what we learned from a 150 kVA build.
Putting AI agents into restaurant operations
Practical patterns for AI voice ordering, demand forecasting and the guardrails that keep them production-safe.
WiFi 6 mesh design for high-density buildings
Roaming, capacity planning and analytics for enterprise WiFi in dense environments.
Building offline-first CBT for unstable networks
How we built a resilient examination engine for schools across regions with intermittent connectivity.
AI video analytics for banking campuses
How modern VMS plus on-prem inference cut incident response under three minutes for a 240-camera deployment.
Smart buildings start with a strong ELV foundation
Why structured cabling, access control and CCTV are the unseen backbone of every successful smart building.
Managed IT vs in-house: a CTO decision framework
When to outsource operations, when to build in-house, and the hybrid model most enterprises end up running.
