Evgeniy Kharam has been developing his soft skills in the technology industry over the last 2 decades after realizing early on that it helped him bridge the gap between engineering and business. This helped him rise in his career. He took the time to document his learnings in his book, Architecting Success: The Art of Soft Skills in Technical Sales.

He joins Buu to talk about the importance of soft skills and how to approach building the skills needed if you're looking to grow your impact.

At AppWorld 2025, Buu Lam sits down with Haiyan Song, Executive Vice President of CloudOps at NetApp as well as Shawn Wormke, Vice President and General Manager, F5 NGINX. Haiyan and Shawn just wrapped up a keynote on stage and swing by the podcast booth to expand on the insights that they shared on stage. With NetApp being the whole of so much of the world's enterprise data, it makes sense for F5 to partner with them to provide fast and secure connectivity as customers seek to get data out to their AI applications for Retrieval Augmented Generation (RAG) architectures.
