Expert freelance services for software development, test automation, and DevOps
Building high-quality, reliable products in a fast-paced company is hard
At a fast-paced organization, 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 tech companies feel like they need to sacrifice quality over speed, but it doesn't have to be that way.
As a software engineer and tester working primarily with startups, I understand the unique challenges and needs of early-stage companies. I also know the benefits of moving fast and rapidly delivering products that delight your customers. With the experience and skills acquired throughout my career, I can help companies with little time to waste and who need someone to come in and provide value as quickly as possible.

What others say about working with me
We've benefited a lot from Dennis's skill and expertise in backend development, DevOps, automated testing, and CI/CD. 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.KDennis 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.

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 GroupOver the years, Dennis has been easy to work with, always patient to explain what he was doing, and was very dependable on results. He went the extra yard to find a solution which kept our application up and running, plus ensured we can continue to do so without interruption into the future. I highly recommend Dennis, without reservation, for any development job, big or small. He is great to work with!
Richard HalpernFounder @ EcoApprentice
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.
Randy BurgessVP of Technology @ MPI Media GroupAlways 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.
