Now, let’s view businesses that have already opted for offshore Python development and benefited from it.
Businesses that benefited from hiring offshore Python developers
Discovery Limited is a South Africa-based financial services group. The company offers a range of financial solutions to both individuals and businesses. We work with Discovery Invest, a part of Discovery Limited, which offers Investment and Pension fund products.
The client needed a partner with robust big data and cloud expertise. We are responsible for building the functionality that calculates additional benefits for certain products in the investment segment.
Discovery Invest encourages and rewards clients for investing longer, living well, and withdrawing wisely. They wanted to find a way to consider the customers’ state of health on an ongoing basis and to inspire people to adopt better lifestyle behaviors.
Adhering to adopting better lifestyle behaviors, our client works on new products to encourage its customers. The client engaged the N-iX team to develop a new solution. Our task is to develop REST APIs and design a pipeline for running, processing, and returning data to the source databases.
Also, as the data was stored on-premise, which is more expensive than the cloud, the client needed a cloud migration plan. Thus, the N-iX team has developed a clear cloud migration roadmap and started its implementation.
American Fortune 500 industrial supply company (under NDA)
This company has 3.2 million customers in categories such as safety, material handling, and metalworking, along with services like inventory management and technical support. This client needed a partner with experience in big data to boost their engineering capabilities. Also, they needed to cut operational costs with the help of cloud migration.
The client requested developing a major big data platform that would contain data from all the company's departments.
Thus, our engineers have created a platform to store all the client's data in one place. Thanks to this solution, the data management is improved, and the whole process has sped up. What’s more, N-iX has fully automated the data extraction process from different sources and covered all the following issues:
- hardware maintenance;
- problems with free memory space on Hadoop and local file system;
- frequent Data nodes outages which cause poor performance for our ETL scripts.
Currently, our team manages all of the processes for processing a large amount of data. The use of Snowflake and Airflow allows us to automate the data extraction process.
The N-iX team has helped the client reduce the production cost because the client replaced half of the contractors (that received approx. $150 per hour).
Switching to the cloud allowed the client to save the cost, as keeping the Hadoop cluster is more expensive than a properly organized cloud.
Vable is a UK information management company set up in 2004, aiming to develop the first newsletter solution for law firms.
Vable needed a dedicated development team to build a new solution from scratch, using technologies, including Python, Angular 8, Java, Node.js, AWS, RabbitMQ, to name a few.
N-iX development team is engaged in full-cycle software development of the new, cloud-based version of the product, which enables further data analysis and aggregation.
At the initial stage, our team worked on the new software architecture. We helped the client migrate from the monolith to microservices to make the solution more scalable and flexible.
Now, there are over 50 microservices: a part of them are written in Python because some of the tasks like crawling RSS feeds are better to manage in Python.
As of today, N-iX has helped the client to:
- develop a DevOps framework on Ansible and Swarm, thanks to which there is no downtime;
- expand the customer's business domain. The old platform was designed specifically for law firms. Thanks to our solution, the customer now also works in the financial sector and healthcare.
The partnership is ongoing.
Origin Enterprises plc is a leading agri-services group providing integrated agronomy services. The company is based in Ireland.
The client needed a technology partner to build a set of solutions, using such technologies as Python, Java, Ionic, and Angular.
The applications serve as digital platforms for farmers, agronomists, and product and credit providers. They offer comprehensive functionality, from optimizing cooperation between parties to efficient estimation and recommendations in agriculture.
Our developers have created a mobile app and several web applications for Origin Enterprises. For example, the N-iX team has developed a progressive web app that integrates modern web capabilities and the benefits of the mobile experience.
AlienVault is a crowd-sourced threat intelligence network delivering a solution for threat detection, incident response, and compliance management.
N-iX started its partnership with AlienVault in October 2015, when the client was planning to develop a new product and needed a partner to address multiple technical tasks with existing products.
While working on this project, we used and configured such tools as Suricata (for NIDS), OSSEC agent (for HIDS), OpenVAS (vulnerability scanning), Nmap (asset discovery and scanning). We performed correlation engine improvements. It was written mainly in C/C++, whereas Sensors code was mostly in Python; web UI was written in PHP. MySQL was used as a database, with a current snapshot of OTX Threat DB being stored in Redis.
The N-iX team helped stabilize the product by releasing dozens of minor and major system patches and providing timely fixes. Our team grewew from 4 engineers to 14 in about a year. To accelerate time-to-market, we launched automated tests by extending the AlienVault Robot Framework and writing new automated test cases.
