About

Frontend developer with 4.5+ years of experience building modern web applications across banking, telecom, and e-commerce.

I build responsive, production-grade interfaces with React, Redux, and TypeScript, with growing hands-on work around Next.js, AI-powered products, and modern frontend architecture. My focus is on building clean, reliable user experiences for complex flows, especially where performance, accessibility, and product clarity matter.

Currently, I work at Infosys for Barclays, where I’m building frontend flows for ChargeCard and related financial journeys. My role goes beyond implementation. I collaborate with backend engineers, architects, and business teams to understand requirements, shape interfaces, and deliver production-ready UI with strong API integration.

I also actively use AI-assisted development in my workflow. Tools like Copilot, ChatGPT, and prompt-based exploration help me speed up delivery, refine solutions faster, and improve development efficiency without compromising correctness or maintainability.

Now

  • Building Barclays ChargeCard frontend journeys from scratch.
  • Working across React, Redux, internal design systems, and API-driven financial workflows.
  • Using AI-assisted development and prompt engineering to accelerate delivery and problem-solving.
  • Strengthening my edge in Generative AI, LLM tooling, and frontend system design.

My day-to-day workflow includes GitHub and GitLab for version control and reviews, CI pipelines for safe delivery, Postman for API validation, and AI tools like Copilot and ChatGPT for faster iteration, refactoring, and development support. I also explore Generative AI tools such as Ollama and LLM-based workflows as part of my ongoing learning.
