Elasticsearch Development Services

Elasticsearch is not as well-known as many tools and technologies but used properly it can give mind blowing results. Let’s start from what is Elasticsearch and how it can improve your business.

In a few words, Elasticsearch is a search engine based on Lucene. Elasticsearch is a distributed, multitenant-capable full-text (RESTful) search and analytics engine with an HTTP web interface and schema-free JSON documents capable of solving various use cases.

Firstly, Elasticsearch helps to perform and combine structured, unstructured, geo, metric, and any other searches needed.

Secondly, Elasticsearch aggregations help to zoom out to explore and analyze trends and patterns in data and understand the bigger picture. This type of Elasticsearch usage is recognized in E-Commerce projects and also loved by business analytics. As metaphorically mentioned on the official website, Elasticsearch helps to discover the expected and uncover the unexpected.

Take a look at some key Elasticsearch cons:

  • Speed;
  • Easy to install and setup;
  • The price (open source under the terms of the Apache License);
  • JSON over HTTP transfers;
  • Scalability (running on several servers is possible);
  • Real-Time indexation;
  • Multi-tenancy;
  • Possible to transfer to the Cloud.

Elasticsearch services are used by various companies and organizations, including such giants as GitHub, Stack Exchange, Blizzard, Dell, eBay, Warner Brothers, Netflix, Facebook, Slack, BBC, Walmart, USAA, and a lot more.

Hire Elasticsearch Developers

Hiring in-house teams or local market players can be expensive and burn a hole in the project budget. No wonder many businesses, from small to large, are looking for offshore partners.

Since for the last few years every future-oriented businesses are interested in data analytics, Elasticsearch development became a highly required service. Outsourcing this type of service allows companies to focus on core competencies and strategy. Therefore, outsourcing is not only effective for saving costs without additional risks but may also minimize business disruptions.

GraphQL Development Services

In short, what is GraphQL and how this technology can make your app greater?

GraphQL is a query language for your API which lets developers describe the complex, nested data dependencies of modern applications. GraphQL is designed to operate over a single endpoint via HTTP, optimizing for performance and flexibility.

Skilled GraphQL developers can use it with any language or platform to define app’s backend as a well-defined schema.

GraphQL provides a complete and understandable description of the data in an API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.

GraphQL queries access not just the properties of one resource but also smoothly follow references between them. While typical REST APIs require loading from multiple URLs, GraphQL APIs get all the data your app needs in a single request.

Long story short, the key benefits of GraphQL app development are:

  • Apps can use types to avoid writing manual parsing code;
  • Apps using GraphQL are fast and stable because they control the data they get, not the server.
  • Apps using GraphQL can be quick even on slow mobile network connections.

Our GraphQL developers can grow your app from a small project all the way to something big. An amazing scalability is one of the main reasons why companies prefer GraphQL. Of course, everything depends on your projects. Here we suggest to you to contact our astronauts to receive a free tech advice about GraphQL, REST and other technologies.

Who is using GraphQL? GraphQL is used by teams of all sizes in many different environments and languages to power mobile apps, websites, and APIs. Facebook’s mobile apps have been powered by GraphQL since 2012. In the list of companies using GraphQL development you will find such giants as GitHub, Airbnb, Pinterest, Coursera, Meteor, Shopify, Mixcloud, M1 Finance, Intuit and others.

The next step will be to find and hire PayPal API Developers and open new opportunities for your business.

Hire PayPal Developers

For many companies, software development services are budget-burners. To cut the software development costs many businesses hire offshore providers and outsource the part of the project or the entire project. In web app development, front-end development, back-end development, Stripe, Braintree, PayPal Integration services are the major parts businesses choose to outsource. The main difficulty is to find a reliable partner that has related experience and resources and can deliver a high-end product you need.

Contact us to choose the most efficient technologies and Payment Processing Systems and get some tips on how to build or improve your product.

REST Development

Let’s start from what is REST and what is its role in the software development process.

REST is not a specific programming language nor a technology, it has no official set of tools or specification. REST development is rather a method of creating APIs (Application Programming Interface, which are methods of connecting with other libraries or applications) with certain organizational principles. It is easy to understand REST as a series of guidelines and architectural styles used for data transmission.

REST is the most logical, efficient and widespread standard in the creation of APIs for web applications, but can pass data to software as well. The focus is on making APIs last for decades, instead of optimizing for performance. Also, REST and REST API development makes the apps horizontal growth possible.

Following REST development principles emphasizes scalability of component interactions, generality of interfaces, independent deployment of components, and intermediary components to reduce interaction latency, enforce security, and encapsulate legacy systems.

REST systems aim for fast performance, reliability, and the ability to grow, by reusing components that can be managed and updated without affecting the system as a whole, even while it is running. These are main reasons why we choose REST development on our KeenEthics spaceship.

Hire REST Developers

Most businesses, especially the rising ones, search for opportunities to keep the budget within reason. One of the ways is to assign the development part to an offshore provider that has lower rates but the same quality.

We understand that finding a reliable nearshore vendor to develop a working software product is not an easy business decision. When hiring a REST development service provider, we suggest to you to consider:

  • company’s years of experience in general;
  • similar or related projects in vendor’s portfolio;
  • match your project’s size with provider’s capabilities.

If you want to save time, contact us and our REST developers will do their best to deliver an efficient solution to your business.

Stripe API Integration Services

When integrating online business with a payment processing system, forward-thinking companies usually choose Stripe API Integration, PayPal or Braintree. Each of these systems works great. The choice mostly depends on your requirements.

Stripe is known as a powerful and flexible software platform for running a business online. Whether you are building a subscription service, an on-demand marketplace, an e-commerce store, or a crowdfunding platform, Stripe Payment System will suit you.

The key features of Stripe are that in almost all cases, Stripe is a cheaper option than PayPal because of lower service fees. Stripe is an always-improving product that gains new features every month. Integrating Stripe API means you get early access to the latest technologies, from Apple Pay to Bitcoin.

Also, Stripe values data portability. If you decide to leave Stripe, your Stripe Developers can migrate your credit card data in a secure and PCI-Compliant way. It is good to know you have a choice, and will not be locked in forever.

Therefore, Stripe API Integration services are good for almost all fields:

  • Mobile Commerce;
  • On-demand Economy;
  • Software as a service;
  • Nonprofits;
  • Platform Payments.

World’s most innovative technology companies are scaling faster and more efficiently by building their businesses on Stripe. Kickstarter, Facebook, Slack, Asana, Wetransfer, Dribble, The Guardian and others use Stripe API Integration services to create the best possible product for users.

PhoneGap & Cordova App Development

2,5 times faster

it is to develop a hybrid mobile app than a native app.

What Is PhoneGap and Cordova?

Cordova, also known as Apache Cordova, is a cross-platform mobile app development framework, which was introduced in 2009. PhoneGap is the most popular distribution of Apache Cordova. PhoneGap and Cordova can be used interchangeably — there is basically only one difference between them. Cordova is free and open source, and so is PhoneGap, but the latter belongs to Adobe. If for some reason you prefer one over the other, we will gladly comply with your request. For us as for Cordova & PhoneGap app development company, there is barely any difference.

Cordova and PhoneGap application development offer a lot of benefits, chiefly — convenience and universality. Yet, these solutions are not a panacea. PhoneGap and Cordova are perfect for prototyping or for internal business applications, which serve as add-ons, not the core of your business. However, if a mobile app is in the essence of your business, you should choose native development instead.

Why PhoneGap and Cordova?

Cordova and PhoneGap let a developer build a mobile app with no knowledge of mobile technologies, only JavaScript, HTML, and CSS.

Both Cordova and PhoneGap are open-source projects. They have large communities of devoted developers, who constantly update and support the frameworks.

PhoneGap and Cordova are supported by multiple libraries, tools, and plugins, which may greatly facilitate the development and advance the software solution.

Cordova and PhoneGap let you bypass the app store approval and deployment process, which will save you a lot of time and effort. Updating a Cordova app may be as simple as updating a website.

The apps built with PhoneGap and Cordova can be used on all popular mobile operating systems, including iOS, Android, BlackBerry, and Windows Mobile.

Cross-platform development is by definition faster and cheaper than the native one. PhoneGap application development company lets you save on both development and maintenance.

Electron Development Services


is the number of stars Electron has on GitHub

What Is Electron Development?

Electron is a runtime framework for cross-platform desktop development, which was initially released in July 2013 by OpenJS Foundation. The idea of Electron is to bridge the gap between web and desktop development and facilitate the latter. Electron framework uses Chromium and Node.js to let you build a desktop app with JS, HTML, and CSS. If you have an existing web app, migrating it to desktop platforms should be no big deal since most of the code can be reused. If you do not feel like learning Electron, request the services of an Electron JS development company.

While desktop apps are not that popular anymore, in some cases, they are necessary. Sometimes, it is just a matter of personal preference. Other times, it is the functionality that only desktop allows implementing. Whatever your case is, if you want to develop a desktop app, we suggest developing it with Electron. This way, you will easily move it to the web if necessary.

Why Electron?

Electron apps are compatible with Mac, Windows, and Linux, so developing a cross-platform desktop application is as easy as it could ever get.

Electron is an open source project maintained by GitHub and an active community of contributors. It has been used to create applications by companies like Microsoft, WordPress, WhatsApp, Slack, Avocode, and inVision.

Electron framework greatly facilitates development. It features automatic updates, crash reports, native menus, and native notifications. Debugging and profiling are also simpler with Electron.

Since Electron spares the need to develop a separate desktop app for each platform, it saves you a lot of development hours. It also saves time for those who move their app from web to desktop
