Sankalan Chakraborty
@sankalanchakraborty
I build accessible, high-performance full-stack web applications with React, TypeScript, Node.js, and databases.
IndiaWhat I'm looking for
At Cognizant, I design RESTful APIs, structure complex Redux state, and build accessible interfaces that meet WCAG 2.1 AA and ARIA standards. I use memoisation, code splitting, and lazy loading to reduce bundle size by 10–12%.
Previously at Tata Consultancy Services, I built reusable UI component libraries, improved responsiveness in data-heavy interfaces, and led accessibility remediation for screen-reader and keyboard users. I collaborated with backend, QA, and product teams through Agile delivery and Git-based peer review.
I also build end-to-end products such as a MERN expense tracker with JWT refresh-token rotation, Redis caching, BullMQ jobs, and Redux Saga, plus a React and TypeScript image library with multipart uploads and animated UI components.
Experience
Work history, roles, and key accomplishments
Design and consume RESTful APIs with server-side validation and relational schema integration. Apply React performance techniques to reduce bundle size and build interfaces to WCAG 2.1 AA standards.
