openPIM

openPIM is a public API platform for distributing rich product information. The data is open and free to use, and while the codebase is private, the project is actively evolving and open to contributors.

I contributed to the backend and infrastructure during a contract engagement, then continued independently by building a companion frontend to demonstrate and test the capabilities of openPIM’s v1 API. For more information, visit https://openpim.io/.

If this tickles your fantasy, feel free to get in touch. No matter your skill set — developer or not — all kinds of contributions are welcome.

Highlights

• Architecture: Horizontally scalable microservice system built with Go, designed for high throughput and modular service development. Internal services communicate via gRPC for performance and low latency.
• Frontend: Next.js frontend served as a standalone app behind an Express reverse proxy, enabling clean API routing and session handling with minimal coupling to the backend.
• Data Layer: Backed by globally replicated MongoDB clusters, optimized for high availability and regional performance. Read/write routing ensures low-latency access from any location.
• Deployment: Runs on AWS EKS with containerized workloads, horizontal autoscaling, and health-checked rolling updates — enabling zero downtime deployments and seamless scaling under load.
• Integration: Built for extensibility with support for GraphQL, REST, and file-based interfaces — making it easy to plug into external systems or build custom clients.
