Experience

Hindustan Zinc Limited

Hindustan Zinc is India’s largest and the world’s second-largest zinc-lead miner that created Evolve, a digital marketplace where B2B customers can buy metals online. Integrated with the London Stock Exchange, customers can monitor live metal prices, watch a live stream of the costs, and place an order accordingly.

I worked as an architect and lead for this project developed using Sap Hybris and Node.js in the back end and Vanilla JS in the front end.
As a result, the client could sell their products online and double the sales within a year.

Electrolux

Electrolux is an eCommerce portal where customers can purchase electronics and get them delivered to their homes. This website has various products and services bundled together, and customers can choose them based on their requirements.

I built this portal for a US-based company, implementing features like CMS, payment integration, and SAP ERP integration using Hybris, Spring, and Java for the back end, and JavaScript and TypeScript for the front end. This helped the client increase online sales.

Multi-country Website | David Yurman

David Yurman wanted a multi-country site where users could buy jewelry online and customize their designs. It has various payment gateways and other ERP integrations. The order management system is developed to manage stocks and orders across multiple warehouses.

I worked as an SAP Hybris developer and acted as a lead for a few modules. I developed multiple functionalities like checkout, emails, ERP and payment gateway integrations, and an order management system. I also contributed to the store's front design using React.

Vodafone Redsky

https://www.vodafone.hu
Vodafone Redsky enables Hungarian users to buy mobiles and pre-configured bundles online. Users can also choose the handset and subscription plan online. The process includes vetting the customer and handling stock and logistics.

On this project, I worked as a developer implementing features like product search, customer vetting, and other integrations using technologies like Hybris, Spring, and Java on the back end. This helped the client sell their products online and increase overall sales.

Wiley Author Services 2.0

https://authorservices.wiley.com
Wiley-Blackwell Author Services enables authors to track their articles online through production to online publication after being accepted by Wiley-Blackwell. Once published online, authors also have free access to their articles in perpetuity, with exceptions for some journals.

I worked as a developer for this project, implementing features like notifications, registration, and other integrations using technologies like Spring, Java, and Hibernate for the back end, and JavaScript, HTML, and CSS for the front end. This helped the client increase online sales.
