Backend development

High quality backend development is a crucial requirement for the success of a web application. It handles the business logic while at the same time ensuring that the front-end is well integrated and delivered, considering each project's requirements.

Even though the backend developer's work is not directly visible for the users, it is extremely important to make a functional and logical web application.

Ledger Leopard provides skilled senior backend developers to our customers, that are able to work with different types of backend languages, API layers and database. We provide the following types of backend developers:

Scala

Scala is a programming language designed with functional principles in mind. Its type system and conciseness make it a pleasant languages to work with. Scala is used by a big community all around the world, and lots of Enterprise companies use it as their basis for a solid system. Scala can be combined with a lot of frameworks and libraries which simplify the development process even further.

Ledger Leopard has a team of senior Scala developers that has to experience to create complex backend systems using Scala and functional programming.

NodeJS

Node. js is widely used to create microservices for the backend and frontend of different kinds systems. Node.js is a lightweight framework that can be used to develop different types of applications such as web applications, real-time chat applications, command line applications, REST API servers, and more.

At Ledger Leopard we provide NodeJs development to our customers for backend requirements, as it is an easy and modern way to implement microservices based systems. 

MongoDB

MongoDB is an open source NoSQL database management program. NoSQL is used as an alternative to traditional relational databases. NoSQL databases are quite useful for working with large sets of distributed data. MongoDB is a tool that can manage document-oriented information, store or retrieve information.

Even though we understand a that a MongoDB is not the solution for everything, and at Ledger Leopard we also have experience with working with SQL databases when the solutions demands it, in most cases we implement our solutions with a MongoDB. As a result of this our team has a broad experience in implementing scalable database solutions.

Rest API

An API (application program interface) is a set of rules that enables different system parts to communicate. It defines the appropriate way for a software developer to compose a program on a server that communicates with various client applications.

Most systems developed by Ledger Leopard are API based. Which means that we have a team of experienced developers who know how to write good working well documented API’s in systems like swagger.

Front-end development

The front-end of a system functions as a tool to present your organization to the world. A good looking front-end communicates trust as well as confidence in prospective clients.

A good front-end development requires a strong understanding of programming languages (such as HTML, CSS, and JavaScript) and graphic design principles.

Front-end developers need to understand how users interact with websites to create an intuitive and user-friendly interface.

Ledger Leopard provides skilled senior front-end developers to our customers, that are able to work with different types of front-end languages and have experience with integrating API. We provide the following types of front-end developers:

JavaScript

JavaScript is not a standalone development language, it includes various Libraries and frameworks, which makes it applicable for a variety of front-end use cases. JavaScript frameworks are collections of JavaScript code libraries that provide developers with pre-written code to use for programming features and tasks. Popular JavaScript front-end frameworks include React, Angular, and Vue.

As we preferably use a NodeJS backend at Ledger Leopard, it is common to combine this with a JavaScipt based front-end.  This forces us to provide our customers with a strong team of senior  front-end developers with a JavaScipt specialization.

Blockchain development

Over the last years blockchain has become a proven and mature technology for many areas beyond financial transactions. Blockchain can optimize business growth by eliminating third-party services, automating processes and make important data trustworthy. It is a transformative technology, that an provide new business models if used wisely.

Ever since 2017, we’ve been extending our experience in the area of blockchain, and our goal is to share and implement our blockchain skillset to help businesses with their digital transformation.

Ledger Leopard provides skilled senior blockchain developers to our customers, that are able to work with different types of blockchain platforms and technology. We provide the following types of blockchain developers:

Ethereum

Ethereum is a decentralized blockchain platform that establishes a peer-to-peer network that securely executes and verifies application code, called smart contracts. Smart contracts allow participants to transact with each other without a trusted central authority.

From the early days of Ethereum, Ledger Leopard belonged to the first companies that was able to implement Ethereum solutions in production.  This frontrunner position is still visible in the amount of expertise our team has with Ethereum, and the proven track record of our developers at customers.

Solidity

Solidity is a programming language designed for developing smart contracts that run on the Ethereum Virtual Machine. Smart contracts are programs that are executed inside a blockchain, where nobody has special authority over the execution, and thus they allow anyone to implement tokens of value, ownership, voting, and other kinds of logic.

As Ledger Leopard is a blockchain and web3 based company, we have a team of developers that have experience with writing complicated smart contracts for a very large amount of systems, use cases and customers.

Hyperledger

Hyperledger is an open source project created to support the development of blockchain-based distributed ledgers. Hyperledger is a collaborative/open source initiative to provide the frameworks, standards, tools and libraries to build blockchains and related applications. Hyperledger provides multiple types of blockchain solutions for multiple type of situations:

Hyperledger Indy

Hyperledger Indy provides tools, libraries, and reusable components for providing digital identities rooted on blockchains or other distributed ledgers so that they are interoperable across administrative domains, applications, and any other silo.

As our own products are based on Hyperledger Indy, and we are working with Hyperledger Indy from the start of the initiative, we have a strong team of highly skilled Indy developers to facilitate our customers.

Hyperledger Fabric

Hyperledger Fabric is a modular blockchain framework that acts as a foundation for developing blockchain-based products, solutions, and applications using plug-and-play components that are aimed for use within private enterprises.

As Ledger Leopard is a blockchain and web3 based company, we have a team of developers that have experience with writing complicated solutions with an high transaction speed, for a very large amount of systems, use cases and customers.

Mobile development

Mobile development is the process of developing applications for mobile devices. That could be real apps; standalone applications. But also progressive web apps; applications built on existing internet technologies.

As web3 systems are most of the time combined with mobile apps, Ledger Leopard is experienced in developing high quality native and hybrid apps for different use cases in multiple areas.

Ledger Leopard provides skilled senior mobile developers to our customers, that are able to work with different types of mobile languages and  API layers. We provide the following types of mobile developers:

iOS

Swift is a new programming language from Apple, built by Apple, that builds on the techniques learned in Objective-C, but modernizes them to include shorter syntax and easier readability, maintainability and safety to prevent crashes. Swift is based around modern practices that are also seen in other modern programming languages like JavaScript, Ruby and Kotlin. Swift is available in the most recent versions of Xcode and can be used to build apps from iOS 7 or later, and macOS devices dating back to Mac OS X 10.9 or later.
