Developing software is a process composed of several key steps: In this article, I will focus on one crucial part of the process: writing code and running it locally. Demo: Observations from Startups and Established Companies Startups tend to move fast. They have fewer meetings, design quickly, implement rapidly, and deploy in record time. However, […]
In this article, I will walk you through the process of configuring WireGuard on EdgeOS. While this setup was tested on a Ubiquiti EdgeRouter 4, it should also work on other similar devices running EdgeOS. Objective The primary goal of this setup is to enable secure connections to a WireGuard server running on the EdgeRouter […]

A bit of history In Java lack of a value can be represented as null or a more readable approach and less error-prone is to use Optional. Using Optional is the recommended way of […]
Dual Writes often happens in a microservices based architecture. Whenever a piece of data changes in one place, we need to persist or react on it on multiple places. Imagine a user bought a product on our website and we need to save order in the database and inform a delivery service that they should […]
