Experimenting with ChatGPT for DevOps

April 07, 2023  ·  1123 words  ·  6 mins

I had been working in the DevOps and Site Reliability space for roughly 5 years by the time that ChatGPT made it’s ground shattering debut to the world, and it truly revolutionized how we all think about work and technology. At Endowus, we strive to see how we can leverage modern technology to its fullest, and in this case, how ChatGPT can help DevOps engineers optimize parts of their workflow.

We had all heard the rumours of ChatGPT being able to write a complete application from scratch. With a healthy level of skepticism, I thought “it can’t really be that good”. So I decided to test it out and see for myself.

Initially, I started asking it to produce small scri…

How Endowus engineers the right tech values

January 01, 2023  ·  806 words  ·  5 mins

There have been many attempts at defining the culture of an organisation. Some claim culture stems from a company’s vision and mission. Others think it’s about perks and benefits.

We think the best articulation of what constitutes a company’s culture is found in Ben Horowitz’s book “What You Do Is Who You Are”, in which he writes:

Your culture is how your company makes decisions when you are not there. It’s the set of assumptions your employees use to resolve the problems they face every day. It’s how they behave when no one is looking.

This rubric of decision making can be captured as that which a company values. As individual contributors, and later as engineering leaders at many different companies, we’ve witnessed first-hand how engineering teams make choices and decisions that are influenced by these cultural values.

Every company, every department, and every team has values. Whether they realise it or not and whether they explicitly write them down or not - they exist and are the invisible force guiding employee behaviours and decision making.
