Platform & Architecture

Infrastructure and deployment patterns used to ship and operate multi-service backend systems, with emphasis on secure configuration, repeatable releases, and operational clarity.

How it ships

AWS EC2 (Ubuntu) · Nginx reverse proxy (TLS via Let's Encrypt) · Dockerized Next.js (portfolio) on 127.0.0.1:3000 · GitHub Actions CI/CD (SSH deploy)

Blue/green deployments use Nginx upstream snippet (ports 3000/3001) for low-downtime releases and quick rollback. See repo docs: NGINX_BLUE_GREEN.md, CI_CD.md.

Security Boundaries

Public: 80/443 via Nginx. App container bound to 127.0.0.1.

Secrets & Configuration

Centralized secrets and safe configuration injection to avoid leaking sensitive data into repos or images.

  • Prefer managed secrets (AWS Secrets Manager / secure env patterns)
  • Avoid committing secrets; keep production env separate
  • Promote rotatable credentials and auditable changes

Reverse Proxy & TLS

Nginx terminates TLS and exposes only HTTPS to the public, keeping app services private on localhost.

  • HTTP → HTTPS redirect
  • Let's Encrypt certificates with automatic renewal
  • Only ports 80/443 public; app binds to 127.0.0.1

Reliability Patterns

Operational Readiness

Production mindset: health, debugging, and visibility matter as much as features.

  • Service health and graceful failure handling
  • Logging and monitoring patterns (CloudWatch / Prometheus/Grafana style)
  • Incident-oriented debugging habits

CI/CD

Automated delivery pipelines with tight feedback loops and predictable deployments.

  • GitHub Actions / GitLab CI/CD / Jenkins experience
  • Build → test/lint → deploy via SSH (for EC2-hosted portfolio)
  • Container-based deployment to reduce host drift

Infrastructure patterns

Terraform as a Control Plane

Terraform is used not only for provisioning but also to standardize configuration patterns across services.

  • Provision and standardize AWS resources as infrastructure code
  • Maintain repeatable environment configuration patterns
  • Support multi-service deployments with consistent inputs/outputs
