ABOUT ME
Hey, I’m Sachin Bagaria, a full-stack web developer based in Luxembourg, with over 5 years of experience turning ideas into fast, scalable, and secure web applications.
I’ve worked with clients across the USA, UK, Australia, UAE, India, and France, delivering 10+ projects. From finance platforms and recruitment tools to hotel systems, hospital apps, and even Web3 products.
I specialize in Next.js, React, Node.js, MongoDB, and Python. But I don’t just build apps. I architect them. From UI to backend logic, performance tuning to clean architecture, I care about every detail. My apps regularly score 90+ in SEO and performance (Lighthouse), and I always aim for pixel-perfect, responsive design.
I'm also passionate about Generative AI. I’ve built tools using OpenAI, LangChain, Pinecone, and Hugging Face, integrating smart AI features that make real business impact. Whether it’s designing APIs, optimizing for speed, or leading dev teams in Agile sprints.
My Skills
Design & Dev Tools
I love bringing ideas to life from Figma. For development and deployment, I work with tools like GitHub Actions, Docker, Nginx, AWS, and Jenkins, plus everyday essentials like Git, Postman, Redis, and Jest to keep things running smoothly.
Full Stack Development
From responsive design to 90+ SEO scores, I build full-stack web apps that perform. I design in Figma, build frontends with React and Next.js, and handle backends using Node.js, Python, Express, and MongoDB. Whether it’s designing clean UIs, building APIs, or planning the app architecture, I take care of the entire flow frontend to backend with speed and clarity.
Generative AI
I love exploring how AI can enhance real-world experiences. I’ve built tools using LLMs, LangChain, and Hugging Face to experiment with prompts, tones, and model behavior. From designing user-friendly interfaces to wiring up AI pipelines with FastAPI and Python, I enjoy making Gen AI more interactive, practical, and fun to use.
