My Green Forest – Investment Platform

For My Green Forest, we designed and implemented a highly scalable investment platform as custom software. The "10,000 Tree Campaign" is based on an Event-Driven Architecture with asynchronous processing of all transaction and campaign data. The PHP backend uses a Domain-Driven Design with clearly separated Bounded Contexts for campaign management, referral tracking, and payment processing. The multi-tenant architecture allows for the parallel management of multiple campaigns with isolated data spaces, while a central API gateway orchestrates all microservice communication. The frontend was implemented as a Progressive Web App with latency-free synchronization, allowing investors to track the status of their tree plantings in real time. A multi-level referral system with cryptographically secured tracking codes ensures the complete mapping of referral chains across any number of hierarchy levels.

The platform implements ACID-compliant transaction management, which processes every investment transaction atomically. All personal data is protected according to GDPR with AES-256 encryption at-rest and TLS 1.3 in-transit. A Role-Based Access Control (RBAC) system with granular permission levels controls data access. Automated audit trails log every data change in an audit-proof manner. Payment integration is carried out via PCI-DSS-compliant interfaces with tokenized card processing. Regular penetration tests and automated vulnerability scans continuously secure the system's integrity.

The system automation of the campaign logic was designed to absorb load peaks through horizontal auto-scaling of worker processes. Connection pooling and query caching at the database level guarantee consistent response times even with high transaction volumes. CDN integration for static assets reduces the Time-to-First-Byte to under 200ms worldwide. This SaaS solution, built to a German Quality Standard, demonstrates how complex business logic can be combined with enterprise-grade reliability—a benchmark for custom software in the investment sector.
