Citrine Software
Bespoke software, infrastructure automation, and secure administrative systems.
Citrine Software focuses on practical solutions for organizations with specific operational requirements — from business workflows and document registration to endpoint management and network automation.
Software built around the problem, not the other way around.
Generic platforms are useful until the workflow stops being generic. The focus is on purpose-built systems that fit existing processes, integrate with real infrastructure, and remain understandable and maintainable over time.
Areas of focus
Business Systems
Custom administrative, accounting, reporting, and document workflow software designed around real organizational processes.
Infrastructure & Automation
Network automation, monitoring, failover, backups, and systems administration tooling for environments where reliability matters.
Security & Identity
QES integration, authenticated workflows, access controls, audit history, and privacy-conscious web tools.
Modern software. Old-school engineering discipline.
Citrine Software favors clear architecture, careful implementation, and solutions that are straightforward to operate and maintain. The goal is not to add complexity for its own sake, but to build software that remains useful long after the initial implementation.

Bandwidth-aware multi-WAN load balancing, health monitoring, failover, backups and alerting.
Network automation · MikroTik · RouterOS · Load balancing · High availability · Monitoring · Backup
Advanced RouterOS automation that distributes traffic across multiple Internet providers according to their configured bandwidth, while independently monitoring each connection through multiple external health targets. If a provider fails, traffic is automatically redistributed across the remaining healthy links and restored when connectivity returns. The system also handles scheduled configuration backups and queued email alerts.
- Bandwidth-weighted multi-WAN load balancing
- Parallel per-WAN health checks
- Multiple external connectivity targets
- Automatic failover and recovery
- Stateful connection evaluation
- Scheduled configuration backups
- Backup failure detection
- Queued email alerts
- Protection against overlapping script execution
