Writing Good User Stories in Product teams
Software Engineers require instructions in order to build apps and tools. And most of us don't know what these instructions should look like. One of the ways these instructions can be shared is in the form of user stories, and it's not just about writing a bunch of text, but comprehensive check list of how this should be structured so the right information can be given to the builder. Ofcourse its a two way effort Product and Engineering need to work closely to build up such requirements so they make sense from a functionality perspective, and a technical perspective. This session is based on the article linked below:

Why I havn't applied to Google as a SE (yet).
Google, or any of the FAANG companies for that matter, are an awesome place to work. When I started by bachelors - I was thinking of graduating and then getting a job there, or build a pathway to a job there. However by the time I graduated, my mind set had changed. In this episode I explore my thoughts and reasoning on what changed my mind and why I havnt applied since.

Should you join a startup today?
With startups going bust left right and center, high inflation and a global recession - are startups still the right choice to be at? In this episode I talk about the difference between the companies treating engineering teams as a profit center vs a cost center, to show why startup engineering teams as usually a better choice even if there is a slightly higher risk being there.

How good is your company's Engineering Culture?
In this episode I break down a good engineering culture using two different culture tests from the web.

Why Should Every Developer Learn Javascript?
Javascript is one of my favourite languages out there. Im not sure if it just the familiarity with the language (have been using it since age 10) or the fast pace of change in the language space or the fact its being used on space craft - I think its a useful skill to have for anyone working in the software industry. Check out my rant on what makes JS so awesome according to me!

Understanding DORA metrics for Software Delivery Performance
As programmers we work hard all day to ensure we build the best products in the best technical way possible, and if that work isn't shipped to customers right away, we are unable to generate any value of it for the company / product. DevOps plays a critical role in our organisations today, and ensure we have an efficient production line shipping features to our customers is a part of it. In this episode we review how we can better understand and measure performance of our software delivery and what does it take to compete with the best out there.

Whats makes a good software engineer?
While mentoring some students with technical interviews, I documented what I find to be most important qualities of a software developer or engineer. While a quick google search online will find mixed reviews, most people feel that technical skills are most important. However I feel a bit differently about this, and in this episode share the things all software engineers should focus on and how they can improve them selves if lacking.

Before joining a startup
The recent failure of the startup Fast got me thinking of things one needs to be aware of while considering to join a startup and things to observe while working in one. This episode covers some basics to what you can do before and after joining which should help you prepare better for the risks involved while working in a startup. This episode was inspired by the following post:

Understanding a Startups Technical Due Diligence...
Technical Due Diligence (DD) for startups is not something we think about until the time really comes in.

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 this episode we dive into the world of tweaking code performance and getting the most out of the hardware its running on.

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?

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.

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: Register for workshop here:

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.

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.
