Ismael Stahelin

I'm a Senior Full Stack Engineer focused on building scalable web applications and distributed systems using Ruby on Rails, Python, React, and modern JavaScript. Over the years, I've worked with startups and international companies developing SaaS platforms, APIs, backend services, and user-focused products used by thousands of users worldwide. My main expertise is backend and full stack development with Ruby on Rails, Python, React, PostgreSQL, and cloud-based architectures. I also have experience with Node.js, PHP, and Java, which allows me to quickly adapt across different environments and technology stacks. More recently, I've been exploring AI-powered applications, LLM integrations, automation workflows, and prompt engineering to create smarter and more efficient user experiences. I enjoy solving complex engineering problems, writing clean and maintainable code, collaborating with distributed teams, and building products that balance scalability, performance, and simplicity. Currently open to remote opportunities worldwide (full-time or contract).
