Engineering that returns control, efficiency and data sovereignty to the organizations that run it.

Building secure, reproducible and production-inspired engineering projects.

Developmi is the personal engineering brand of Miguel Lozano.

This organization hosts open-source projects focused on infrastructure engineering, networking, DevSecOps, cloud architecture, security automation, and self-hosted platforms.

The goal is simple:

• Build practical engineering tools.
• Share production-inspired architectures.
• Promote infrastructure sovereignty.
• Contribute reusable open-source components.

Projects here are production-tested. Not prototypes. Developmi is not a company and does not provide commercial support through this organization. Client-specific implementations, proprietary Infrastructure as Code, and consulting deliverables remain private.

Management UI for caddy-waf. Go stdlib only, zero runtime dependencies. Centralized control plane for WAF rules, logs and threat visibility.

Ansible framework for bare metal - NIST 800-53 aligned, Tailscale zero-trust mesh, CrowdSec, Vault-backed secrets, Molecule tested.

Sovereign ELT platform - dlt + dbt + ClickHouse + Metabase. Multi-tenant, RBAC-isolated, 93 automated quality tests in production.

Developmi projects follow a consistent engineering philosophy:

• Security by Default
• Reproducible Builds
• Infrastructure as Code
• Supply Chain Security
• Minimal Operational Complexity
• Automation First
• Semantic Versioning
• Open Standards

Open-source repositories published here represent reusable engineering components intended for the community.

Commercial implementations, customer infrastructure, and proprietary automation remain outside this organization.

Security is not a feature; it is the baseline.
