Developer's avatar

I'm a full-stack Rails developer with a focused, thoughtful approach and a strong interest in clean, maintainable code. Before I got into programming, I studied classical guitar — and that training still shapes how I work: with patience, care, and an eye for detail. I enjoy understanding systems deeply and building software that’s simple, useful, and built to last.

New profile

I’m a full-stack Ruby on Rails developer with 3+ years of real-world experience building and maintaining production software in a small, fast-moving team. Before becoming a developer, I trained and worked professionally as a classical guitarist—an experience that taught me patience, precision, and a commitment to lifelong learning. I now bring those same qualities to building clean, maintainable, and thoughtful software. My path into programming was driven by a passion for analytical thinking, which led me to study Mathematical Technical Software Development part-time. During my studies, I joined a small remote-first company, where I quickly moved from working student to full team contributor. There, I shipped features across the stack—writing tests, squashing bugs, and taking ownership of projects from planning to deployment. My day-to-day tools include Ruby on Rails, Hotwire, RSpec, PostgreSQL, Redis, Docker, and Vue.js. I enjoy diving into the internals of systems, not just getting things to work, but understanding why they work. I’m also active in open-source and maintain two Neovim plugins focused on improving Rails workflows. Currently, I’m building BudgetBuddy, a personal finance tool that puts my full-stack skills to the test. Whether collaborating in a team or building on my own, I value clear communication, craftsmanship, and continuous improvement.

Senior Full Stack Software Engineer

New profile

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.
