I know Mr. Kalpesh Patel for the last 5 years. He is sincere, dedicated, and a very keen learner. I have worked with him where he acted as a teacher, mentor, and coach. One thing I liked most about him is to focus on delivering beyond expectation. He has always been a person who believed in "Going beyond possible" to create something of value for the customer. He says - This is just the beginning. The best is yet to come. I know for sure that with this powerful philosophy, Annexe is going to create many new milestones for the industry. I wish Kalpesh bhai all the very best.

The concept of Lorem Ipsum, also known as fake text, has stood the test of time and has become a pivotal element for designers. It allows designers to create their designs with realistic text that appears genuine, despite serving as a mere placeholder for future text insertions. Despite the advancements in technology, the relevance of Lorem Ipsum has not faded, as it continues to remain popular within the design community. This timeless technique has been in use for an extended period, and has seen adoption throughout multiple mediums. Initially, designers made use of Letraset sheets to incorporate the Lorem Ipsum text within their designs, but with the advent of software such as Aldus PageMaker, Lorem Ipsum is now generated quickly and dynamically. Rest assured, if you have ever come across striking designs with impeccable text spacing and thoughtfulness, you are likely seeing the innovative and classic technique of Lorem Ipsum in action.
