Software Engineering, Big Data & Analytics

We are a technology outsourcing partner which helps tech driven companies to efficiently scale their engineering efforts quickly.

Our teams of agile practising problem solvers have specialised in building infrastructure to enable real time big data processing and enable our clients to extract value from vast amounts of information. Engineers at South Gate Tech deep dive into the business problems of our clients and are regularly contributing to the strategy and business outcomes of the products they build.

We employ people who love to code and learn new technologies so it is hard for us to define strict boundaries of the tech stack we work with, although we are best at: Python (Flask, Faust), Java (EE, Spring, Hybernate), JavaScript/Node, Go, Hadoop, Redshift, Kafka, SQL Server, Oracle, Tableau, Qlikview, PowerBI, ... Startups love us because we can ramp up teams quickly without compromising the quality. We do that by constantly investing in our internal recruitment capabilities, having referrals and leveraging our network of contacts. We are a people first company and as such we constantly invest in our engineers, we help them discover and master new technologies and skills, mentor them to focus on what brings value for the business by applying the best agile practises for that purpose.

BeAble FullStack Dedicated Team – Learning Platform For School Students In The US Image

BeAble FullStack Dedicated Team – Learning Platform For School Students In The US

We were contacted by BeAble – an American start-up company based in New Jersey to help them build their MVP.

Their main focus is on creating the Beable platform, including three major sections: rostering, taxonomy and literacy web-apps. The goal of this platform is to allow the enrollment of new students with literacy problems, which will then proceed to be assessed,

and will ultimately be offered lessons in their predefined subjects, prepared specifically for their literacy level. An example of that would be a student in the 10th grade, who receives his material written for the 8th grade, so that he understands better and works his way up.

Technology – wise, the platform is built on top of micro-services architecture with a strict hierarchy of interfaces and helper libraries, as the main stack is NestJS, ReactJS (with hooks), MySQL and AWS.
