Yasin Engin Network Backend

Enterprise Network Inventory REST API

A Go and PostgreSQL source-of-truth API for modeling network assets, access control, and operational data.

Go PostgreSQL JWT RBAC Docker

Problem

Network teams need a reliable source of truth for locations, devices, interfaces, VLANs, users, audit logs, and operational metadata. The project turns that inventory problem into a typed API with predictable validation, authorization, filtering, and pagination.

Architecture

The service separates HTTP routing, authentication, authorization, request validation, persistence, and audit logging. That structure keeps the API readable while making operational controls such as role checks and change history explicit.

Data Model

Locations and network devices as the main inventory hierarchy.
Interfaces, VLANs, operational state, and ownership metadata.
Users, roles, authentication claims, and audit events for traceability.

What I Built

Structured REST endpoints with consistent request and response behavior.
JWT authentication and role-based access control for protected operations.
Validation, filtering, pagination, and operational audit logging.
Docker-native deployment path for local testing and repeatable setup.

What I Learned

A network inventory API is strongest when data modeling and access control are designed together.
Filtering and pagination are not UI extras; they are operational requirements for real inventory work.
Audit logs make backend behavior easier to explain, test, and debug.

Future Improvements

Add OpenAPI documentation and generated client examples.
Connect inventory state to network automation validation workflows.
Add Prometheus metrics for request latency, error classes, and audit event volume.
