I'm Dennis Martinez

Helping startups build high-quality applications, from testing to development to deployment

Building high-quality, reliable products in a fast-paced startup is hard

At a fast-paced startup, you typically focus on how quickly you can bring your company's vision to life. Unfortunately, it's not as simple as putting all your focus into delivering your product. Startups have a seemingly infinite number of areas pulling at the entire team's attention. With scarce resources, you must balance planning your roadmap, developing new features, fixing bugs, customer support, and much more.

In the middle of all the chaos, you want to build a high-quality product that won't create headaches for you or your customers. In today's world, the expectations of your customers are lofty. They want your service to provide a fast, reliable experience while you deliver new features to delight them. But to achieve that, it takes lots of time and effort. Chances are you won't have the capacity to spare to focus on the current and long-term quality of your applications.

Most startups feel like they need to sacrifice quality over speed, but it doesn't have to be that way.

You need a freelancer with the right skills and startup experience who can integrate quickly with your team to improve the quality of your applications.

As a software engineer and tester working primarily with startups, I understand the unique challenges and needs of early-stage companies. With the 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 also have deep knowledge of Amazon AWS services as a AWS Certified Solutions Architect, AWS Certified Developer, and AWS Certified DevOps Engineer.

What others say about working with me

Dennis is not only reliable, he handles challenges with a mix of rational problem-solving and big-picture thinking. He's recommended solutions and chosen technology that fits our context and needs as a startup. His eye for process and detail is to be envied and has become the gold standard for members of our development team.

      Allen W.
      Co-Founder @ Sollective K.K
    • 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
    • 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.

      Cindy W.
      Senior Technical Business Analyst @ Onsite Rental Group
    • Dennis is one of those guys who can do just about anything. We worked together on a pretty tricky port of a Rails/Ember.js app from Heroku to being able to run standalone in Docker and he solved all of the difficult parts. Hire him as quickly as possible.

    • Over the years I have worked with Dennis on a variety of custom software projects, across the full stack of backend and front end applications, for a number of different clients. In every scenario, he is one of the best software engineers on our teams in terms of pragmatic problem solving, consistent communication, and on-time delivery of the needed solutions. I cannot recommend Dennis highly enough for anyone considering to bring him on their project or team.
