Background

About Sayantan Dev

As a full-stack engineer with 13+ years of industry experience, I’m currently focused on transitioning into AI/ML and data-centric product development. I have hands-on expertise in building Python-based backend services and microservices using FastAPI and Flask, integrated with modern data workflows and analytics systems. I actively work with libraries like Pandas, NumPy, Scikit-learn, TensorFlow, and PyTorch for prototyping intelligent solutions. Beyond Python, I bring extensive experience across the MERN stack (MongoDB, Express.js, React, Node.js), enhanced with TypeScript, GraphQL, PostgreSQL, and Redis, enabling the development of robust, scalable, and high-performance applications. I’ve led and mentored teams through architecture planning, CI/CD pipelines, performance optimization, and full product lifecycles. My work spans healthcare platforms, toll analytics systems, and SEO-optimized eCommerce solutions using Next.js, GraphQL, and cloud services like Azure, AWS, and Heroku. Currently, I’m aligning my full-stack engineering strengths with data-driven product strategy and AI-enabled innovation, seeking roles at the intersection of software engineering and intelligent systems.
