Areas of expertise
Architecture you can build on
A focused, senior practice led by Anton Sigurjónsson, senior enterprise systems architect. Deep, hands-on expertise across the work that keeps complex systems coherent — senior, direct, and close to delivery.
System design & integration
Designing how systems fit together: clear boundaries, robust integration and data flows that stay dependable under real-world load.
Distributed & message-based systems
Event-driven, message-based architectures — decoupled services on message brokers and service buses (e.g. RabbitMQ, NServiceBus) that stay reliable and observable at scale.
Cloud & Azure architecture
Well-architected cloud on Microsoft Azure — landing zones, infrastructure-as-code and cost-aware designs that scale with the business.
Security & certificate lifecycle
Security architecture and certificate-lifecycle management built into the design — informed by shipping CertainGuard, not bolted on later.
Modernization & technical strategy
Pragmatic modernization paths and technical strategy — sequencing change so legacy systems evolve without grinding delivery to a halt.
Hands-on engineering leadership
Senior, hands-on leadership through delivery — setting direction, raising the engineering bar and staying close to the code that matters.
Products & ventures
We build our own products, too.
Alongside the architecture practice, the same hands ship real software through G9, a product house — and CertainGuard, a product for dependable certificate and security lifecycle management.
