Hi ✋ I'm Ed from the Philippines 🇵🇭

I'm a backend developer with 15+ years of experience building complex enterprise systems. Along the way, I realized something important:
I needed a place to document, refine, and share what I’ve learned.

That’s how czetsuyatech 💡 was born.

🧠 What I Do

I create practical, code-first content to help developers build real systems—not just tutorials, but things you can actually use in production.

I write blog articles 📚 (with source code) and create video tutorials 📺 covering:

  • Programming principles
  • Microservices with Spring Cloud
  • Serverless (AWS Lambda, Quarkus)
  • Identity & Access Management (Keycloak, Cognito)
  • Backend (Spring, Quarkus)
  • Frontend (React, Angular)
  • Databases (PostgreSQL, MySQL, Liquibase, Flyway)
  • Event streaming (Kafka)
  • Source control & build tools (Git, GitHub, Maven, GitLab)
  • Containers (Docker, Docker Compose)
  • Cloud (AWS / GCP)
  • DevOps & application servers

I’m also an active open-source 🌱 contributor and maintainer.
I strongly believe in learning by coding—getting your hands dirty is where real growth happens.

🚀 Open Source, Content, and Commercial Work

Most of my content, articles, and open-source projects are free 🆓 for the community.

Recently, I’ve also started building production-grade commercial libraries (like nerv-audit) to solve real-world problems at scale.

👉 Sponsorship helps me continue doing both:

  • Maintain and improve free content & open-source
  • Build high-quality tools for serious use cases

🤝 Why Sponsor Me?

Your support 💰 directly helps fund:

🔐 Custom Keycloak Server

ct-keycloak-iam

  • Custom Dockerized Keycloak Server (free)
  • Custom login page (free)
  • Custom storage (in progress) 💰
  • Multi-tenant support (in progress) 💰
  • N-level resellers (in progress) 💰

⚡ Serverless for Startups

As someone building my own startup, I’m deeply focused on cost-efficient architectures.

I’m creating content and real implementations around:

  • Serverless frontend (React + AWS Amplify)
  • Serverless backend (Quarkus / AWS Lambda / Spring Native)
  • Serverless databases (AWS Aurora)
  • Serverless messaging (AWS MSK)

The goal:
👉 Help developers and founders build scalable systems with minimal cost

💖 What Sponsorship Means

Sponsorship is a way to support my work—not a replacement for commercial licenses.

It helps me:

  • Create more high-quality technical content
  • Maintain and expand open-source projects
  • Share real-world architecture and lessons learned

🙏 Thank You

Thank you for reading, watching, liking, sharing, and engaging with my content.

You—developers, readers, and builders—are my biggest inspiration 💌
Helping even one person grow in their career makes all of this worth it.

I would be truly grateful for your support 🙏

@czetsuya

It will be a milestone achievement if I reach this goal, as it validates that the materials I've published are relevant and valuable. I will start hosting programming-related events and build an active community of programmers. I'll randomly pick one sponsor at a time and acknowledge them on my blog https://www.czetsuyatech.com.
