Post & Go Kiosk Platform
Multi-National Self-Service Postal Platform
Post & Go was a large self-service kiosk platform built for postal operators across multiple international territories, including Royal Mail, Post Office, Jersey Post, Guernsey Post, Gibraltar Post, Correos, Greenland Post and the Faroe Islands postal service.
The platform allowed customers to buy stamps, purchase postage, process parcels, make payments and access postal services through public self-service kiosks. Over several years, it evolved into a flexible platform that could support different clients, languages, branding, hardware setups and postal workflows from a shared codebase.
My Role
Technical Director & Lead Developer
I led the technical direction of the project while managing a team of three developers. My role covered architecture, hands-on development, team leadership, stakeholder management, project planning and technical presentations to internal teams and client representatives.
Technical Challenges
This was not a one-off build. It was a live kiosk platform that needed to remain stable and maintainable over many years while running in unattended public environments.
The software had to integrate with a wide range of hardware, including payment devices, printers, barcode scanners, weighing scales and other specialist kiosk peripherals. Reliability was a major focus, particularly around hardware recovery, transaction safety, fault handling and long-term operational stability.
To support multiple postal operators, I helped design and evolve a modular architecture that allowed features to be enabled, disabled or customised per deployment. This meant the same core platform could support different clients without needing separate codebases for each version.
The project also involved deeper platform integration than a typical Unity application, including custom Android plugins for kiosk hardware and Unity-to-Windows Forms integration for lower-level Windows hardware communication.
Key Contributions
Led the technical architecture and long-term development of the platform.
Managed and mentored a team of three developers.
Designed a modular feature system for different client deployments.
Built a flexible UI theming system for multiple branded versions.
Implemented multilingual support across the platform.
Developed custom Android plugins for kiosk hardware integration.
Integrated Unity with Windows Forms for lower-level Windows hardware communication.
Worked on payment integrations and transaction workflows.
Improved reliability, maintainability and operational stability.
Presented technical solutions and platform capabilities to stakeholders and clients.

Outcome
Post & Go became a highly configurable self-service platform supporting postal and retail workflows across multiple international operators.
For me, the project was a strong example of long-term technical ownership: leading a team, managing complexity, supporting live public systems and making architectural decisions that kept the platform stable, flexible and maintainable over time.
