Are you a T-Shaped Developer?
T-Shaped developers are those interested in learning across a breadth of technologies ranging from frontend to backend to devops. In this episode we try to understand why would we want to diversify vs specialise and is there a better option between the two?

Thinking about Engineering Analytics
Do you feel your team is very sluggish and not moving fast enough? Do you feel there are constant blockers which are stopping the features to get shipped?

Understanding how ESOPs or Share Options work
You might have been reading about one of the dozen multi-million dollar investments made into startup recently. And you might be wondering how do I get a piece of that action. Most companies now offer their shares to employees through whats called an ESOP. This allows you to accrue value over time and if the company wins big - so do you! This and more in this episode.

Demystifying PCI DSS - Do I need it?
PCI DSS is a security standard certification which a company requires if they have card payment integrations on their websites. However its one of those topics which sounds scary, not talked about enough and is very specific to each company. So understanding even if it is a requirement for your company becomes a pain. In this episode I share my experience going through the certification with Sastaticket and what I learnt during that.

How do I write faster code?
In order to write faster code you need to understand (or profile) your current code and visually or numerically breakdown the pieces which need improvement. How do you do this? We use code profilers! In this episode we dive into the world of tweaking code performance and getting the most out of the hardware its running on.

Mono Repo vs Multi Repo
Mono repos is not a new concept - but one often visited by growing organisations to help reduce the overhead of managing thoses dozens of repos in the company. Is it better? Well that depends on the company and how they work. In this episode I go through the differences and reasons why one would consider a mono repo over a multi repo.

Do I need monitoring and observability for my web app?
Now a days even a simple CRUD based app can have a lot of moving parts - esp if deployed with something like Kubernetes. Our complex applications are growing even faster, interacting with many different libraries and handling greater and more variable loads. How do we get insight into whats really happening on the code level any more? Long gone are the days when a simple CPU usage alert would be enough to monitor most applications - today we need to monitor on different level and metrics to get a better picture of whats going on. This and more in this episode.

AWS EKS, ECS and EB - Containers Galore!
As Docker and Containerisation have taken over the world - we have many different options to deploy our apps to. Within the AWS ecosystem, we have a few options from EKS, ECS and ElasticBeanstalk. While the latter might sound like an outdated option in front of EKS and ECS, it is surprisingly useful - this and more in this weeks podcast.

You Dont Need A CTO
Gone are the days when we need tech teams to setup a simple website. Now a days we simply sign up like we do for Gmail and have everything setup in no time! And it costs just a few dollars per month. No Code tech is awesome and its here to make those mundane development roles redundant. With loads of new tools out there from making simple websites to building complex data entry apps or dashboards - the ecosystem is moving fast to empower the non-technical folks out there so build tech is more accessible and it becomes easier to innovate.

How to write better technical documention.
Writing documentation is not something we think about every day - but it is something we are interacting with on a daily basis. In a world of ever changing requirements and technology, if we are not documenting our technical journey properly - we are simply rebuilding the same wheel again and again. Documentation is at the core of any product, how its build, why it's built that way. And in this podcast we cover how we write this documentation in the best way possible. This is a summary of the technical writing course linked below. Technical Writing Docs:  https://developers.google.com/tech-writing/one Register for workshop here: https://docs.google.com/forms/d/e/1FAIpQLSc26RofABVtJkF1gRE7Pm7u2RBd6NBRbdqtYVUxYD_DVKwVUg/viewform

Using Asynchronous Python with Celery
Writing async code is important when building any application. You dont want your threads to be blocked on http calls and db look ups - esp if the language you are using is single threaded! I was surprised to find that most code written in Python is synchronous though that is now rapidly changing. Writing asynchronous code right now means using libraries like Celery which do all the work in a separate process. What is it, how do we use it and how does it work - this and more in this episode.

Microservices vs Monoliths: which one is better?
Micro-services is the popular architecture pattern which has taken the world over by storm. The promise of small manageable applications with fast iterations and seamless efficient scaling  has attracted many developers on taking on this as a default pattern for all their apps. But we should not be too quick dismiss the handy old monolith. In this episode we take a dive into micro-services to see if they are really that amazing underneath.

An Introduction to Continuous Integration
Continuous Integration (CI) is slowly becoming one of the main pillars for software development. As our software becomes more complex we add more and more tooling around it to automate, so we can focus on whats important - writing code. CI is what runs most of that tooling and keeps it out of the way.. until we need break something and it needs our attention. It gives us the confidence to deploy, again and again so that we move faster in this rapidly changing world.

AMP enables the creation of websites and ads that are consistently fast, beautiful and high-performing across devices and distribution platforms. It is an opensource toolkit which can be used for static pages as well as dynamic ones. But why do we need AMP? And how does it make our web faster? This and more in this short introduction of AMP HTML.
