A modular map of practice domains
The segmentation below describes operational domains and capability clusters. It is not a legal “group” structure and implies no corporate affiliation. It is a taxonomy for clarity (taxonomia ad usum).
Platform & software engineering
End-to-end engineering across full-stack systems and platform primitives: .NET, PHP, Node.js, Java, Python; backend services; API architecture; OAuth; webhooks; microservices; multi-tenant SaaS design; self-hosted AI models; CI/CD pipelines; observability.
- Architectural artifacts: ADRs, interface contracts, threat models, dependency maps.
- Integration patterns: event-driven systems, webhook mediation, API gateways.
- Security primitives: encryption (AES-256), secrets management, least privilege, hardening.
Interpretation: emphasize durable design over ephemeral tooling.
Infrastructure & hosting architecture
Infrastructure is treated as designed capability, not commodity. This includes managed hosting, dedicated instances, enterprise deployments, cloud integration, CDN and traffic engineering, and automation.
- Topologies: HAProxy, load balancing, anycast routing, hybrid Windows/Linux environments.
- Automation: Docker, Kubernetes, provisioning pipelines, IaC patterns.
- Edge & delivery: Cloudflare integration, caching strategy, controlled latency profiles.
Data, reliability & security
Data architectures and reliability engineering: PostgreSQL, MariaDB, Redis, connection pooling, high-availability patterns, security audits, infrastructure hardening, firewall/VPN design, WireGuard. Where applicable: disk rescue and professional data recovery.
- Reliability: failover strategy, RPO/RTO framing, incident playbooks.
- Security: audit trails, baseline hardening, segmentation, access control models.
- Compliance inputs: privacy-by-design, contractual constraints, regulatory interfaces.
Hardware & applied systems engineering
Physical systems as part of the overall stack: server builds, compute clusters, render systems, performance tuning, custom cooling, embedded systems, CNC workflows, 3D printing, LED control, electrical and energy integrations, smart home and building automation.
- Compute: GPU infrastructures, render pipelines, cluster composition.
- Embedded: ESP32, LoRa, edge systems, sensor/actuator control.
- Radio integration: amateur radio competence (CEPT Class 1) for selected use cases.
