I'm Dennis Martinez

A freelancer helping startups with their software engineering and test automation needs

Finding a high-quality freelancer is hard

Finding a freelancer with the skills and experience needed to jump into a fast-paced startup and contribute immediately is tough. Many freelancers may not have enough hands-on experience working in early-stage companies and need lots of hand-holding to get up to speed. Other times, they'll generate subpar work that requires someone else to come in to fix or ends up unused.

Skills alone aren't enough, either. Even if you find a freelancer with the ability to do the work you need, you need to ensure they have clear and effective communication skills. It's not uncommon to have freelancers leave you in the dark about their progress or disappear altogether, leaving you with an incomplete project and wondering what went wrong.

You probably have experienced this yourself, and it's cost you a lot in wasted time and money—precious resources when you're getting your company off the ground.

You need someone with the right combination of skills, experience, and communication skills to help your startup take off and thrive.

As a software engineer and tester working primarily with startups, I understand the unique challenges and needs of early-stage companies. With my experience and skills acquired throughout my career, I can help companies like yours—startups with little time to waste and who need someone to come in and provide value as quickly as possible.

Meet Dennis

As a freelancer and consultant, I work with tech startups across the globe to help them build effective, high-quality software. It's my mission to help these companies get their idea off the ground quickly and in the right way for the long haul.

For over 18 years, I've worked with startups and small organizations across the globe to help them successfully build effective, high-quality software. My experience comes from working with early-stage companies in New York City and San Francisco and remotely with dozens across the globe.

My main areas of focus are full-stack web development, test automation, and DevOps. I love sharing my thoughts and expertise around test automation on my blog, Dev Tester, and have written a book on the same topic. I'm also an AWS Certified Solutions Architect and AWS Certified Developer.

    • Dennis was extremely generous in sharing his knowledge and genuinely wanted to help us out. He looked at our situation and within hours was able to tell us why what we were trying to do wasn't working, what needed to be fixed, and gave us alternative solutions if we wanted to change course. Dennis provided exactly the type of expert guidance we desperately needed.

    • Always a pleasure to work with! Dennis is highly professional and very quick to respond. I wish all my contractors (and employees) were as incredible as him.

      Project Manager @ Mogu Technologies
