Michael E.
Technical Consultant & Developer
About
Hi, I’m Michael Epelboim, a Full-Stack Developer with over five years of experience building scalable web applications, intuitive user interfaces, and AI-powered tools. I specialize in JavaScript, TypeScript, React, Next.js, Node.js, and Ruby on Rails, and I’m passionate about creating solutions that are both functional and user-friendly. In my most recent role at Tromero Ltd., a SaaS company, I developed user interfaces that empower customers to perform complex AI workflows with ease. I rebuilt the frontend for a GPU compute marketplace, redesigned the navigation system to improve usability, and launched tools for AI model fine-tuning and customization. I also created a fully typed Node.js SDK, simplifying integration for developers, and built the company’s documentation website from scratch. My work consistently received positive feedback for improving user satisfaction and delivering results under tight deadlines. As a co-founder of YouCoder, I led a team of four to develop an interactive coding lesson platform, mentoring junior developers and ensuring the timely delivery of the MVP. I’ve also co-founded Shanghai Kaiyu, an ed-tech company that created a learning management system for children’s reading programs, and I’ve mentored over 20 aspiring developers as a Lead Instructor at Le Wagon. I thrive on solving complex problems, whether it’s designing AI workflows, optimizing codebases, or creating seamless user experiences. My diverse background in tech, education, and business has given me a unique perspective on delivering impactful solutions. I’m currently seeking a challenging role as a Full-Stack Developer or Software Engineer, where I can leverage my technical skills, leadership experience, and passion for innovation to contribute to meaningful projects. Let’s connect and explore how I can help your team build something amazing!
