I'm a passionate Full-stack Developer with hands-on experience in building SaaS platforms, AI chatbots integrations, and scalable web applications . Proficient in modern JS and Python stacks with a strong focus on LLM integration, chatbot systems, and web application architecture.
My full name is Jean Chrinot Velombe, but I like to be called by my
last name. I'm originally from Madagascar — the world's 4th largest
island 🌴 and a place full of natural wonder, culture, and
creativity. Currently, I'm pursuing a Master's Degree in Computer Engineering at Kocaeli University, in Türkiye, diving deep into both the theoretical and practical sides of building powerful software systems.
My journey into tech started with curiosity and a laptop, and today, I bring together the power of JavaScript and Python stacks to craft everything from sleek frontends to robust backends. Whether it's creating an AI chatbot, designing a SaaS product, or integrating complex APIs — I thrive on turning problems into elegant digital tools.
With over 6 years of professional experience as a Full-Stack Developer, I specialize in building modern, scalable web applications using JavaScript (Next.js, React) and Python (Django). I've contributed to SaaS platforms, AI chatbot integrations, and customer support automation tools—crafting both frontend interfaces and backend architectures. My work spans from startup environments to academic research projects, combining clean code, user-centered design, and automation to deliver impactful solutions.

My tech stack includes a blend of modern tools and languages that I use to build efficient and maintainable software. I work with React, Next.js, and Tailwind CSS on the frontend to build responsive, interactive UIs. On the backend, I use Python and Node.js to develop APIs and application logic. I also integrate databases like PostgreSQL, MySQL, and MongoDB, and use cloud services like DigitalOcean for seamless deployment. For AI-powered applications, I work with LLM frameworks such as LangChain and LangGraph to build intelligent, context-aware systems.
From AI tools to full-stack platforms, these are the projects where I turn ideas into real-world solutions using modern tech like Next.js, Python, and more.
