Hi there, I'm Dennis Martinez 👋

I'm a freelance software engineer currently living in Osaka, Japan. I work with small to medium-sized tech startups to help them build effective, high-quality software from testing to development to deployment.

🛠️ Skills & Expertise

With over 20 years of experience working with startups and small organizations worldwide, I specialize in a variety of areas, including:

  • DevOps engineering
  • Full-stack web development (primarily Ruby on Rails)
  • Test automation for web applications

Besides my long-running career, I also hold a few certifications that have allowed me to expand my knowledge to help companies with their needs:

📝 Blogging & Writing

Besides coding, I love sharing my thoughts and expertise around test automation on my blog, Dev Tester. With over 125 articles written since 2020, I've been writing to help others become better testers with fully-fledged tutorials and advice on doing their best work within their organization.

I also write for my personal website with insights, tutorials, and resources covering topics such as Ruby on Rails, AWS, Terraform, and more.

🤝 I'm Available For Work - Let's Chat!

Whether you want to schedule a call with me, have a question I can help with, or want to say hi, I'd love to hear from you.
