Small teams frequently have to compete with bigger, more structured organizations who are capable of allocating more resources to project management, and software release management in particular. This means that small teams, or even individual developers, need to properly organize and execute their release process in order to keep up.

In this article, Toptal Freelance Software Engineer Lucas Mancini focuses specifically on small startups, teams that don’t have, or can’t afford, DevOps support, or teams that don’t have a formal process defined for releasing new versions of their product. The author provides a suggested checklist method to manage releases, tailored to match his past experience working on different projects, together with some recommended best practices and guidelines.

The Hadoop Distributed File System (HDFS) is a scalable, open-source solution for storing and processing large volumes of data. With its built-in replication and resilience to disk failures, HDFS is an ideal system for storing and processing data for analytics.

In this step-by-step tutorial, Toptal Database Developer Dallas H. Snider details how to migrate existing data from a PostgreSQL database into the more efficient HDFS.

Performance and data interoperability are critical to the success of any web application. For web apps that need to support video processing – which is inherently compute- and I/O-intensive – these challenges are particularly acute. In this post, I describe some of my experience successfully incorporating video capabilities into a PHP-based web app, leveraging open source technologies and cloud-based services to the greatest extent possible.

As a result of smartphones and mobile applications becoming so popular, web developers have been looking for ways to create mobile applications using JavaScript. This increased demand has led to the development of many JavaScript frameworks capable of running native-like applications on mobile devices.

In this article, Toptal Freelance Software Engineer Johannes Stein compares the current two most popular choices for mobile-oriented JavaScript frameworks, Cordova and React Native. Examining their advantages and pitfalls, he dives into details of each and compares them across different disciplines.

GraphQL is a domain-specific language for data query and manipulation by Facebook. It is meant to replace the de facto REST standard in API creation.

In this article, Toptal Freelance GraphQL Developer Ioram Gordadze creates a GraphQL API from scratch, summarizing problems new GraphQL developers face. He also teaches us to rethink the standard methods used in REST APIs in a more GraphQL-friendly manner.

We shouldn’t listen to what customers say. Instead, we should focus on what they do. Deeper user research will allow us to find out the true needs, wants, and motivations of our customers.
