Tanvir Sheikh

Commerce-focused product engineering, carrying forward the ownership built across three companies.

Moved from writing components to owning frontend architecture — acting as principal developer on marketplace-scale products, leading development, running code reviews and setting the technical direction for UI, performance and SEO.

• Principal developer on marketplace products, owning frontend architecture end to end
• Owned API integration and technical SEO, working directly with backend developers
• Optimized performance through asset optimization, lazy loading and reduced render-blocking scripts

Started as a junior developer and grew into a contributor who could take frontend and backend work interchangeably — from React and Next.js interfaces to Node.js, Adonis.js and Express APIs.

• Built frontend interfaces with React, Next.js and headless WordPress/GraphQL integrations
• Worked across the stack with Node.js, Adonis.js, Express.js, MongoDB and MySQL
• Practiced disciplined Git workflows, code review and dependency management
