Need to build a web application, improve an existing Rails product, or add AI features to your platform? I help teams turn requirements into working software with Ruby on Rails, React, and Next.js. With 7+ years of experience building production applications, I can handle both the backend and frontend—from APIs and business logic to the interfaces your users interact with. Here’s where I can help: • Full-stack development: Build and extend web applications using Rails, React, Next.js, and Vue.js. • Backend systems and APIs: Develop permission management, integrations, reporting, PDF generation, and data export workflows. • AI integration: Add AI-powered knowledge bases, multi-agent workflows, and agent handoffs to existing products. • Existing applications: Investigate bugs, improve database queries, and make complex code easier to maintain. My experience includes shipping a multi-agent AI system for a volunteer-coordination platform, building permission architectures with recursive queries, and developing structured data export pipelines. I regularly use Claude Code, Codex, Antigravity, and GitHub Copilot in my development workflow. These tools support implementation and problem-solving, while I take responsibility for the architecture, code review, testing, and final delivery. You can expect clear communication, practical technical decisions, and a developer who understands how the frontend and backend fit together. Send me a short description of your project, your current stack, and the main challenge you’re facing. We can discuss the scope and the best next step.
