The neglected tech arctic winter — Internal SaaS expenses
The current tech winter has a number of glaring stories — cyclical as they may be, there’s one truth that’s been gleaned over more than the rest; the money spent on internal software tools to support tech infrastructure is bloated. And there’s nothing cyclical about this infrastructure spending.

One year at Last9
I completed one year at Last9 today. When I joined Last9 on April 20, 2020, last year, I was unsure how it would pan out. I only knew Nishant and Piyush - founders of Last9 from the Pune tech community. But I had never worked with them before. I was also unsure about the product Last9 was building. I had never worked in the SRE domain. I didn't know anything about the problems the SREs of the programming world face. I was also a Rails developer, having worked primarily on Ruby on Rails for 6-7
