Business Requirements
Our client and partners launched a locker network. They needed an app that could be installed on the locker tablets and serve as the interface between users and the cloud infrastructure.
Solution
PYGIO built a system that connects the tablet (and by extension the locker) with a robust, reliable transfer protocol to a load balancer and ultimately Application servers.
1
Integrated Firebase for data, auth, and analytics.
2
Automated event logging for parcel movements and diagnostics, with scheduled syncing every couple of hours.
3
Automated deployment across iOS and Android stores.
4
Enabled offline + online functionality via SQLite databases.
5
Established real-time communication using gRPC and MQTT.
This locker project directly supports DSV’s enterprise goal of operational excellence and customer-centric logistics.DSV aims to reduce operational costs, improve customer experience, and increase supply chain visibility.
Our team developed an Android app for locker tablets to serve as the interface between users and the cloud infrastructure. The locker system supports operational excellence and customer-centric solutions at the micro-level, while the enterprise data platform supports predictive analytics, sustainability, and adaptability to market volatility.

Logistics Executive at Global Mobile Distribution
We engaged PYGIO for a custom software development project under exceptionally challenging circumstances. Our customer provided a very limited business requirements document, scope, and initial design. As we unpacked our customer’s requirements through various one-on-one engagements, we realized that this project would be challenging. Our objective was to build a bespoke system to replace third-party software that had been integrated into their previous service provider. PYGIO rose to the challenge.
Despite the absence of a client-side technical team, the PYGIO team took on the critical task of accurately defining requirements while controlling the project’s scope and prioritizing deliverables. Their expertise ensured that the application was functional as quickly as possible, tailored to our specifications. PYGIO’s adaptability, dedication, and skill in navigating such a dynamic environment were truly outstanding. We are incredibly grateful for the successful outcome they achieved.
