Development and design

Reactive Tech Limited can design and develop tailored applications based on your requirements.

We have over 20 years of experience with extensive portfolios delivered for the Financial and E-commerce industries. We developed FX trading applications for a leading international investment bank. And we developed real-time charting applications for a leading Spread-betting and CFD company.

We can deliver low latency and highly resilient applications using tech stacks such as Java, Go, JS, Html5, Python, PHP, Flutter mobile development, PostgreSql and Kubernetes.

Kubernetes and cloud infrastructure

We can help your IT department to set-up, secure and manage Kubernetes clusters.

We set-up public/private and portable Kubernetes clouds on bare-metal servers. This approach prevents our customers from being locked in proprietary cloud providers.

We open-sourced Kubegres which is a Kubernetes operator allowing to deploy self replicating and resilient PostgreSql clusters. We offer support to companies using "Kubegres".


We have over 20 years experience with PostgreSql and MySql.

We offer consulting services on database design and replication strategies.

The Kubernetes PostgreSql operator Kubegres that we developed internally is the proof of our experience in the database domain.

Agile and Scrum

Agile allows teams to deliver applications and new features iteratively with short feedback loops.

We are Scrum master certified and we can assist your teams with training and how to implement Scrum.
