How much does it cost to build an app?

I’ve been running a mobile and web design and development company for more than 3 years now, and – as also the lead of sales – I often hear the following question: “I want to build Uber (or WhatsApp, Airbnb, etc), but a bit different. How much would it cost?”. Every time I hear that question (and I’ve heard it A LOT) I feel the urge to answer: “Considering that Uber raised $3.5 billion dollars, and at least 5% of their funds were focused on its technical infrastructure (apps, servers, websites, data centers, etc), your app should cost something around $350 million USD”.

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.

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.

Cloud scaling: from 1K to 1B users

We all use a lot of web applications, such as Gmail, Evernote, LinkedIn or Telegram as productivity enhancers in our daily lives. However, there are not-so-rare moments that these services go down for a variety of circumstances.

In a recent event, due to Brazil’s Department of Justice decision to block access to WhatsApp in the whole country for 48 hours, millions of Brazilian users suddenly migrated to Telegram, generating a huge (and unexpected) load in their servers. Since this is not the first time this happens, Telegram was well-prepared and handled the usage peak gracefully (even though there was an SMS service bottleneck).

However, in a previous user base sprout, Telegram had a 2-hour outage in some parts of the world, as they said in their official Twitter.

Don’t get me wrong: I think Telegram was totally on top of this. The fact that they could solve this issue in a 2-hour window says they were prepared for cloud scaling – which unfortunately isn’t always true for all web services.

So how can you prepare for scaling? How can you be sure the cloud service you’re creating is prepared to handle a big user base (or a sudden increase in access) without going down?
