Product validation: what to consider before building an app

Building a product is no easy task. It’ll take months of planning, design and engineering work, but with dedication, hard work and the right professionals by your side, it can be accomplished. However, how can you know if you’re building the right product? Dedication and hard work alone won’t be enough. There’s another factor to consider on the equation: if it solves a real problem for real people. Many startups often decide to go straight to the building phase and end up missing some important steps of the product development process, such as validating their business idea with potential customers and analysing the market. Let’s go over some things to take into account when setting a product strategy.

TDD on mobile dev, a matter of timing

When we start the development of a product, there is always a desire to make it as perfect as possible: fulfilling client’s expectations, offering a good learning opportunity to the developer and delivering a system with high maintainability and scalability.

As the code base grows, keeping it problem-free becomes a harder challenge. Testing manually each module of the application can take so much time that developers may become unproductive.

Using the VIPER architecture on Android

Starting as an Android developer and later working with iOS as well, I had contact with several different projects’ architectures – some good and some bad.

I was happily using the MVP architecture for Android until I met – and worked eight months with – the VIPER architecture in an iOS project. When I came back to Android, I decided to adapt and implement VIPER on it, despite some other devs suggesting it wouldn’t make sense to use an iOS architecture on Android. Given the fundamental difference between Android and iOS’ frameworks, I had some questions about how useful would VIPER be for Android. Would it be doable and worth the effort? Let’s start with the basics.

A girl who codes: Why that matters

Think of a professional who has changed the history of IT for a second. If the person who came to your mind was Steve Jobs, Bill Gates or any other male name, it’s no wonder. Although the history of computing is marked by contributions from great women, such as Ada Lovelace, Grace Hopper, Sister Mary Kenneth Keller and Hedy Lamarr, women are still seen as if they played a secondary role in this market.

5 Quick Tips To Increase User Engagement on Your App

If you are not considering the user experience when designing a new mobile application, it’s time to start thinking about it. One of the most important things to have in mind when you design a mobile app is making sure that it is useful and intuitive for the users. If it’s not useful, it won’t have a practical value. At the same time, if the application is useful, but it takes too much time and effort to be used, people won’t engage with it.

API Design: Think First, Code Later

As a software developer, I know how hard it is to contain the urge to start coding as soon as we can. After the first sprint planning, our fingers – uncontrolled, hungry creatures – want to start smashing the keyboard, translating our ideas into code fastly and furiously.

Despite how great we feel while developing, it’s always a good idea to take a step back, especially when building something that could be used by many different users – like an API is. A. In this post, I’ll show you why and how to design a properly-thought API.

Code Review: Easier Better Faster Stronger

Yes, you read it right. I took the liberty to adapt Daft Punk’s song title to talk about code review. As I write this, I’m wondering  if it is going to pass the thorough examination of the chief editor, but I like how the title sounds (and it really describes how a Pull Request should be). And you see, even this harmless piece of text is going over a rvesoin revision process before you can have the chance to be struck by my insights, so why shouldn’t we do the same with our code?

My experience with ReactiveX and asynchronous programming

As a software developer, I must deal with asynchronous programming on a daily basis. In order to provide the best user experience possible, all tasks like performing a server request, getting data from my database, waiting for some background process to finish or downloading an image should be executed asynchronously.

Even with some years of experience, I sometimes forget the syntax for a particular asynchronous call. How should I implement the callback for a specific task and how should I handle the error if anything goes wrong? There are hundred of ways of dealing with responses, and as a developer it’s my job to know which one fits best in every situation. When I first read about ReactiveX I thought: “Great, another asynchronous API to memorize…”. Well, I couldn’t be more wrong.
