I'm Leonard S. Aireman, and I'm a

DevOps & Cloud Engineer Who Builds Real-World Systems

I design reliable cloud infrastructure, automate CI/CD pipelines, and lead incident response. As a SaaS founder, I also teach how to build and monetize production-ready SaaS products in 4 weeks.

Some of my Certifications

I'm a hands-on DevOps / Cloud Engineer with real production experience across infrastructure automation, CI/CD, reliability, security, and SaaS delivery.

This portfolio isn't theoretical. Every project here reflects how I actually work:

  • defining problems clearly
  • designing scalable systems
  • automating everything possible
  • documenting decisions
  • and learning from failure when things break

What I Work With Daily

Not a wall of buzzwords

DevOps & Cloud

  • AWS (VPC, EC2, RDS, IAM, ALB)
  • Terraform (modular IaC)
  • GitHub Actions, CI/CD pipelines
  • Docker & Kubernetes

Reliability & Security

  • Monitoring & alerting
  • Incident response & postmortems
  • Least-privilege IAM
  • Secure infrastructure design

Applications & SaaS

  • Python, Flask
  • WordPress (plugins, performance, hosting)
  • SaaS architecture & monetization
  • Automation & integrations

How I Approach Engineering Problems

  • Understand the real problem — not just the ticket
  • Design for scale and failure — before writing code
  • Automate everything — infrastructure, delivery, recovery
  • Document decisions — for future engineers (and myself)
  • Learn from incidents — systems improve when teams do

This approach helps me deliver systems that last — not just pass tests.

Who This Portfolio Is For

  • Hiring managers evaluating DevOps, Cloud, or Platform Engineers
  • Teams that care about reliability, automation, and clarity
  • Companies shipping real products, not toy systems

If you're looking for someone who can own infrastructure, improve delivery, and stay calm when production breaks, you're in the right place.
