Currently, I am working in Delhivery as a Senior Software Developer, and I have worked with DXC Technologies with overall 3 years of experience which needed a high level of DSA knowledge to develop highly scalable applications from scratch such that they can handle billions of events in a single day by using concepts of Design Patterns like SOLID concept, Factory Pattern etc. I am good with Java, Golang and Python and can help you with LLD and HLD as well. I have solved 400+ DSA questions and have excellent exposure in the problem-solving area.
