Dragan S.

I’m a full-stack software engineer working with web development, AI, and data science. I’m also pursuing a master’s degree in Artificial Intelligence and Data Science, building on my hands-on experience with machine learning and language models. I work with React, Next.js, Node.js, Laravel, Python, and PostgreSQL. I can build an application from scratch or join an existing project to add features, fix issues, and improve how it works. My AI and data science experience includes NLP, data analysis, and training and evaluating machine learning models. For my bachelor’s thesis, I compared small and large language models for sentiment analysis, measuring their accuracy and computational requirements. What I can help with: • Web applications, SaaS products, and dashboards • Frontend and backend development • AI integrations, chatbots, and document search using RAG • Data cleaning, analysis, and visualization with Python • Machine learning model training and evaluation • APIs, third-party integrations, and bug fixes I’m Top Rated on Upwork with a 100% Job Success Score and 38 completed jobs. I ask questions early, communicate clearly, and keep you updated as the work progresses. Send me a short description of your project and what you need help with.
