o Implement data handling, synchronization flows, caching, and processing pipelines;
o Create modular backend libraries reusable across Android, Windows, and web environments.
* Integration & API Communication
o Consume REST APIs and implement secure, fault-tolerant communication flows;
o Design API clients, network layers, and structured request/response models;
o Work with backend teams to refine API contracts and optimize data exchange.
* Multi-Platform Architecture
o Contribute to building cross-platform backend capabilities inside .NET MAUI apps;
o Ensure backend components perform reliably across different platforms and device constraints;
o Optimize for performance, memory usage, and offline scenarios.
* Embedded HTTP Services
o Contribute to features involving lightweight HTTP servers or local service endpoints;
o Help implement local REST/HTTP communication between components.
* Quality, Optimization & Tooling
