Been working in this field since Microsoft 2010 and yet loved every aspect I could approach with these technologies. From Development to training, consulting, architecture to pre-sales, I’ve been enjoying the path because I am able to see the impact of my work in people daily work life.
Initially, I posted on my blog what I couldn’t find on the internet about troubleshooting issues about SharePoint. Then it evolves into reviews, and notes for myself, before I forget :).
