Portal Development, Rollout and Support for OSSO Energy
Summary
The OSSO Gas project demonstrates Vesper’s ability to deliver a secure, maintainable and operationally important digital platform from discovery through rollout and ongoing support.
The project required Vesper to understand the client’s workflows, define user roles and technical requirements, build a responsive web platform, implement secure cloud infrastructure, manage separate environments, run testing, coordinate launch and continue supporting the platform after release.
Client Context
OSSO Gas required a secure digital platform to modernise and centralise important operational processes. The organisation needed to move away from fragmented or manual workflows and create a web-based portal that could support staff activity across quotes, contracts, meters, billing and related operational tasks.
Vesper Software Limited was engaged to design, develop, launch and continue supporting the OSSO Gas platform, a secure business-critical digital service.
Project objectives
The client needed a secure, maintainable and scalable web platform that could support important operational workflows and reduce reliance on fragmented manual processes.
The objectives were to:
understand existing operational processes
define the required user roles and workflows
design and build a secure web-based portal
centralise key operational modules
provide a responsive interface for staff users
implement role-based access control
establish secure cloud infrastructure
create separate environments for safe development and testing
implement CI/CD deployment pipelines
support monitoring, logging and operational resilience
coordinate launch and provide post-launch support
continue improving the platform after rollout
Scope of work
Vesper delivered the platform from planning through rollout and ongoing support.
The work combined application development, responsive interface design, cloud infrastructure, security controls, role-based access and operational workflow development.
The project included:
solution discovery and technical planning
responsive web interface development
staff portal development
quotes, contracts, billing and meters modules
role-based access framework
secure cloud infrastructure
separate development, testing, staging and production environments
CI/CD deployment pipelines
monitoring and logging
file storage and data handling
testing, launch coordination and post-launch support
ongoing maintenance, optimisation and enhancement
Discovery and technical planning
Vesper began by understanding OSSO Gas’s operational processes and translating those into a practical platform architecture. The team worked collaboratively with the client to define the core modules, user roles, workflows and technical requirements. This discovery and planning stage was essential because the platform needed to support real operational tasks, not just provide a visual interface. The work required Vesper to understand how different users would interact with the system, what data and workflows needed to be centralised, and how the platform should be structured to support future growth.
Delivery approach
The delivery approach was agile and structured. Work was organised around clear modules and priorities, allowing the platform to be developed iteratively while keeping stakeholders involved throughout. Collaboration tools such as Jira, Slack and Figma were used to manage tasks, communication and design review, giving the client visibility over progress and decisions. The team included developers, QA, project management and design support, allowing Vesper to take responsibility for both the technical build and the delivery process.
Technical implementation
The OSSO Gas platform was built as a secure, cloud-hosted web platform. Vesper implemented an AWS-based architecture using modern infrastructure and deployment practices.
The technical setup included:
ECS Fargate for application deployment
Aurora Serverless v2 for database services
Lambda and EventBridge for background automation
S3 for file storage
CloudFront for content delivery
CloudWatch and CloudTrail for monitoring and logging
KMS and HTTPS for encryption and secure communications
Terraform for infrastructure as code
GitHub Actions for CI/CD
AWS Identity Center and IAM for secure access management
The platform was built with segregated environments for development, testing, staging and production. This allowed changes to be developed and tested safely before production release, reducing operational risk and supporting a controlled rollout process.
Security and reliability
Security and reliability were central to the project. Vesper implemented role-based access, secure infrastructure, encrypted communications, logging, monitoring and controlled deployment processes. The role-based access model ensured that users had appropriate access to the parts of the platform relevant to their role. Secure cloud infrastructure and encrypted communication helped protect the platform and its data. Monitoring and logging supported operational visibility and issue diagnosis.
Responsive interface and user experience
The platform included responsive web interface development so that staff users could access and operate the system effectively. The user experience needed to support practical operational workflows across quotes, contracts, billing and meters. This required clear screens, logical workflows, appropriate user permissions and a structure that helped staff complete tasks more consistently. Although the OSSO Gas project was not commissioned as a public-sector WCAG audit, it required Vesper to think carefully about usability, clarity, workflow design and responsive access.
Timescale management and rollout
The OSSO Gas platform required careful management from discovery through launch. The project involved multiple modules, secure infrastructure, environment setup, QA, stakeholder communication and post-launch support. Vesper managed the work through structured planning, agile delivery, regular communication and controlled release processes. Separate development, testing, staging and production environments allowed the team to build and test changes safely before rollout. Launch coordination was handled closely with the client, including practical communication channels for issue resolution and final release support. This allowed Vesper to respond quickly during rollout and ensure the platform was stable for operational use.
Quality, testing and rollout
Quality control included QA testing, environment-based release management, technical review and launch coordination. The platform was tested before rollout to ensure that core workflows were functioning correctly and that the system was stable for operational use.
Testing and quality assurance covered:
core workflow testing
role-based access checks
interface review
release testing across environments
technical review
infrastructure and deployment checks
monitoring and logging review
post-launch issue resolution
The launch was coordinated closely with OSSO Gas, including practical communication channels for issue resolution and final release support.
Ongoing maintenance and optimisation
Following rollout, Vesper continued to provide platform support, maintenance and enhancement services.
This included:
issue resolution
technical updates
monitoring support
optimisation
further development
release support
operational improvements as client needs evolved
Outcomes
The project created a central digital platform for important operational workflows, replacing fragmented processes with a more structured and maintainable system.
secure web-based portal for staff workflows
centralised quotes, contracts, billing and meter management
improved operational visibility and consistency
separate environments supporting controlled development and release
automated deployment and infrastructure management
monitoring, logging and secure access controls
ongoing maintenance and enhancement capability
