Each case study is intended to show the operating environment, constraints, decisions, systems involved, and lessons that transfer into present-day technical work.
Case-study purpose
The strongest technical portfolios do not merely list technologies. They explain judgement. These case studies are designed to show how I approach communications problems, infrastructure reliability, regulatory workflows, remote environments, public-facing systems, and practical recovery.
Interior Alaska storm communications
A cornerstone case study connecting prolonged infrastructure failure, amateur radio emergency communications, Alaska conditions, message clarity, and operational calm.
Open case studyMail infrastructure and deliverability
DNS, PTR, SPF, DKIM, DMARC, TLS certificates, Mailcow, Postfix/Dovecot, Rspamd, mobile client configuration, and the operational reality of running independent email.
Matrix + IRC bridge infrastructure
Interoperability between decentralized chat and traditional IRC, including Synapse, bridging, identity mapping, channel behaviour, and service restoration.
ClearSession and Wireless Exam Gen
Regulatory workflow design, applicant registration, FCC Form 605 handling, VE coordination, accessibility, identity verification, and session integrity.
Aurora IRC Client
Desktop UX, packaging, dependency handling, Linux distribution support, update flow, visual state management, and communications usability.
ColdCore IRCd and IceLink Services
Custom IRC server/services development focused on operational simplicity, services integration, user/channel control, logging, SSL, and maintainable deployment.
Self-hosted cloud and privacy stack
Nextcloud, Matrix, Jitsi, Vaultwarden, nginx vhosts, certificates, DNS, mobile integration, and infrastructure ownership across U.S. and New Zealand servers.
Satellite and rural communications
HughesNet, rural connectivity, Starlink planning, remote service expectations, field access, and the difference between ideal networks and practical networks.
How each case study will be written
Evidence templates and current status
Interior Alaska storm communications
Remaining cases
Mail infrastructure, Matrix/IRC bridging, exam systems, satellite communications, and self-hosted cloud operations will be kept honest as incomplete or evolving until each case is fully written with Context, Problem, Action, Result, and Lesson.
Connection to New Zealand
These case studies are especially relevant to New Zealand because many of the same themes recur: geographically distributed communities, rural connectivity, maritime and aviation relevance, emergency communications, infrastructure resilience, open systems, practical field service, and the need for calm technical ownership when services matter.
