The reverse job board for Rails developers

Over 10 years of experience going from 0 to scale as an Engineering and Product Leader 6× Founding Engineer of multiple successful companies, including a telehealth unicorn Ruby on Rails enthusiast, building real tangible value since v3

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.

I’m a senior full-stack developer with over a decade of Ruby on Rails experience, having started with it back in 2012. I was immediately hooked by how quickly I could bring greenfield ideas to life using Rails, and despite experimenting with other stacks—like Go, TypeScript, and even Salesforce—I always find myself returning to Rails for its elegance, productivity, and ecosystem. What makes me unique is a strong focus on code maintainability and developer empathy. I’m deeply influenced by the SOLID principles and aspire to write clear, change-friendly code, taking inspiration from people like Sandi Metz. In recent roles, I’ve often been the person brought in to refactor legacy codebases, introduce design systems, and reduce complexity—turning code that others fear into something a team can iterate on confidently. I’ve worked remotely for companies across the US, Australia, and New Zealand, collaborating across time zones to ship features, reduce tech debt, and keep product momentum strong. I'm passionate about building tools that people enjoy using, and I leverage AI tools to improve my speed and consistency, giving me more bandwidth for creative problem-solving and mentoring.

At Owens Corning via Toptal, I introduced a reusable geolocation service adopted by 9 datasets and built a multilingual translation engine that improved LATAM and Canadian outreach. My contributions consistently reduce costs, enhance UX, and modernize legacy systems with measurable results. Skilled in Ruby on Rails, React, Symfony, Postgres, Docker, Redis, and CI/CD pipelines, I thrive in remote, agile environments, leading teams with a balance of technical depth and collaborative mentorship.
