Challenge
Deploy a project and portfolio management platform for large industrial enterprises, with a multi-tenant foundation for standard clients and dedicated single-tenant instances for enterprise accounts, isolated data and seamless experience (Gantt, alerts, real-time KPIs).
Ensure advanced security, high performance at scale, and automated multi-environment deployments, combining shared and dedicated models.
Solution
Serverless cloud architecture on AWS: multi-tenant foundation for standard clients and pipelines provisioning dedicated single-tenant stacks for enterprise accounts.
Enhanced security: multi-tenant isolation, granular roles, secure links, encryption, and full traceability across both deployment models.
Responsive web interface to manage projects, Gantt charts, and dashboards in real time, even on large datasets.
Quality and reliability: automated tests and CI/CD pipelines for fast and stable releases.
Result
Platform deployed with several major industrial clients, featuring reinforced SLAs and accelerated onboarding thanks to multi-tenant templates and automated single-tenant deployments.
Controlled performance (stable latency under load), audited security, and empowered client teams through documentation and tech lead mentoring.
