About Sebastian Bergman

Hello everyone! I’m an aspiring Full-Stack Developer with a strong foundation in Front-End development using React, JavaScript, TypeScript, HTML, CSS & Sass and experience in Back-end development using Python, FastAPI, LangChain, LangGraph, MongoDB, Express and RAG (Retrieval-augmented generation). I recently graduated with a degree in Business Information Technology from Haaga-Helia University of Applied Sciences, where I’ve spent the past three years building technical depth across web development, backend systems, and emerging technologies. Over the course of my studies and projects, I’ve gained hands-on experience with a variety of languages and frameworks including React, React Native, Java, Spring Boot, HTML5, CSS, Node.js, Vue.js, Python, and SQL. I’m driven by curiosity, excited by problem-solving, and thrive in both team environments and self-directed work. In addition to full-stack development, I’ve grown increasingly passionate about Generative AI and am actively pursuing a career in the field. I've already completed several GenAI-focused projects, including a Retrieval-Augmented Generation (RAG) agent leveraging LangChain, Azure OpenAI, and MongoDB as a vector store. Through these projects, I’m rapidly building a solid technical foundation in GenAI, and I’m especially interested in how these technologies can be integrated into user-focused, full-stack applications to create smart and adaptive systems. My thesis explored user-centered design and its influence on programming outcomes — strengthening my understanding of the crucial link between development and UX. I also completed an internship where I applied and expanded my skill set in a real-world IT environment. Fluent in both Finnish and English, I communicate clearly in diverse teams and enjoy working on projects that combine creativity, technology, and impact. Let’s connect and collaborate on building the future through code, innovation, and meaningful design!
