https://sayantanghosh.in +91-7697505444 sayantan.ghosh03@gmail.comAs a Senior Software Engineer, I specialize in crafting robust and intuitive user experiences with React.js, TypeScript, and Next.js. My expertise extends to the backend with Express and database solutions like PostgreSQL and Supabase, enabling me to build full-stack web applications from concept to deployment.
I'm passionate about exploring how AI can augment development workflows — tools like Cursor and V0 have become part of my daily toolkit. I've also built a strong foundation in prompt engineering, recently earning Google Prompting Essentials certification.
Outside of work, you'll often find me building full-stack web apps as hobby projects, playing video games, or sharpening my tactics over online chess matches.
Always excited to connect with fellow developers, AI enthusiasts, and builders!
