Hire senior Ruby on Rails developers in United States

I am a software engineer with ten years of professional experience. I have a proven record of writing clean and maintainable code, delivering on company objectives in a timely manner, and providing effective code reviews, high-quality communication, and mentorship to team members and direct reports. My expertise lies primarily in backend API development in Python and Ruby. I am also experienced in frontend development and infrastructure management in AWS. Wherever I find myself in the stack, I always focus on delivering secure, performant solutions.

I started writing apps at 8 years old in Microsoft Access with my Dad. Then 3d games in BASIC, and finally in college PHP and MySQL web apps. Never looked back. Mid-Level/Senior Software Engineer capable of independently developing and assisting in the design of products loved by customers and associates, with many years of experience with full-stack technologies in a cloud environment, and back end technologies such as Java and C#. Great attention to detail with well-architected systems and enjoyable user interactions. Strong communicator with interpersonal savvy.

I'm Dallas Hart, a Senior Full-Stack Software Engineer with over a decade of experience building scalable, secure, and AI-integrated applications across fintech, healthcare, and e-commerce. My career has been driven by a passion for solving real-world problems through clean architecture, intelligent automation, and collaborative product development. My journey began with a love for building things that make people's lives easier — starting from early scripting projects to leading cloud-native application rollouts used by thousands. I’ve architected HIPAA-compliant health portals, PCI-secure payment platforms, and AI-powered fraud detection engines — all while optimizing for performance, reliability, and user experience. Whether I’m modernizing legacy systems or deploying microservices on AWS Lambda, I keep my focus on delivering measurable business outcomes. One of my proudest achievements was leading the development of a patient portal that reduced admin workload by 30%, while also integrating third-party AI to personalize content and drive engagement. I also designed a fraud detection system that cut chargebacks by 26% — blending ML with real-time Kafka and GraphQL. I bring a rare combination of deep technical expertise, strong product sense, and cross-functional collaboration. I thrive in environments where I can work closely with stakeholders and turn ambiguous business needs into robust systems that scale. If you're looking for someone who can own the full stack, drive AI integration, and push for engineering excellence — I’m your guy.

Hi, I'm Mike! I've spent the last decade working on Rails at scale--from high-traffic APIs to complex backend systems. Beyond Rails, I've built React frontends within Rails applications, shipped React Native apps, and developed native iOS applications. What I bring to teams: * Code quality at scale - I implement systems (RuboCop, ESLint, automated testing) that keep large codebases maintainable as teams grow * Performance-first mindset - I use observability and metrics to identify bottlenecks before they become problems * Deep debugging skills - Whether it's a memory leak in production or a race condition in tests, I'll dig in until we find the root cause Recent technical interests: Hotwire/Turbo, LLMs, agents, and contributing to open source.
