I'm a software developer. I mostly do Python. This blog is about my adventures with code, travel experiences and relevant life events. I try not to take myself too seriously.
Here's what I'm doing now.
Occasionally I give talks.
Please don't take my words for granted, because Internet is full of bad advice, and I might be part of it inadvertently.

It’s nice that development server is so kind to generate Datastore indexes for us, unfortunately those aren’t always optimal and might require some tweaking from our side. Hence it’s important to be knowledgeable on intricacies of index creation. This is...
If you’ve been developing apps to host on Google App Engine (GAE) and use Google Cloud Datastore database (further referred to simply as Datastore), then you are probably aware of indexes. Simply put, indexes are what makes reads faster with...
