CAPABILITY MATRIX

SECTOR 02/05

C-01

BACKEND & API

REST APIs, authentication, business logic, service integration, and the shape of the backend itself.

PRIMARY
C-02

INFRASTRUCTURE & SELF-HOSTING

Docker and Compose, VPS, reverse proxies, Cloudflare, deployment, and a homelab that stays up.

PRIMARY
C-03

DATABASE & DATA SYSTEMS

PostgreSQL as the spine, Valkey for cache, ClickHouse for analytics. Schema, indexing, access paths.

PRIMARY
C-04

LINUX & SYSTEM ADMIN

Desktop and server: packages, services, storage, networking, permissions, logs, process management.

PRIMARY
C-05

AUTOMATION & TROUBLESHOOTING

Automating repeat work, and reading errors until the real root cause surfaces — not the first symptom.

PRIMARY
C-06

FRONTEND DEVELOPMENT

Web UI wired to APIs: state, data flow, responsive layout, and an architecture no larger than needed.
