Experience
Robert Walters New Zealand Website
The main challenge this project entailed was making a header component. I had to make the custom core component while also making a header. My work also included writing code using Sightly with Apache Sling models and creating templates, experience fragments, content fragments, and technical documentation for the website.

REWE DAM
The main challenge was integrating AEM Assets with Dynamic Media and Brand Portal and publishing it. Publishing to DM is out of the box, but publishing to BP is not supported in AEM as a CS, so we had to write custom code for publishing.
NDMA India
We ended up using Spring Boot. This project's main challenge entailed making their site available in multiple languages, i.e., Hindi and English. They also wanted to make a type of CMS to update content on the go.
Lhotse CMS
