Platform Engineering Blueprint

Building Internal Developer Platforms on AWS. Reduce developer cognitive load, increase deployment frequency and measure what matters.

Overview

Platform Engineering is the practice of building and running an Internal Developer Platform (IDP) that enables product teams to self-serve their infrastructure needs. The platform team builds the infrastructure layer; product teams consume it through well-defined APIs.

The result: developers deploy to production without opening an ops ticket. New services are scaffolded in minutes. CI/CD pipelines are inherited, not written. Security controls are built into the platform, not added after. DORA metrics track whether the platform is actually improving developer velocity.

Platform Pillars

Golden Paths

Standardized ways to build, deploy and operate. Developers follow the path — platform team maintains it. Paved roads for API service, frontend SPA, background worker and scheduled job patterns.

Self-Service Infra

Developers provision a new database, S3 bucket or EKS namespace without an ops ticket. Terraform modules exposed as APIs. Guardrails built in — only allowed configurations are possible.

CI/CD Templates

Reusable GitHub Actions workflows for every service type. Build, test, scan, push, deploy — inherited from the platform. Teams get production-grade pipelines from day one without writing YAML.

DORA Metrics

Deployment frequency, lead time for changes, mean time to recovery and change failure rate. The platform exists to improve these numbers — not to add process. Measured weekly.
