PromptID
PromptID is an AI-native EdTech platform for employers and universities that examines learners for real, in-depth understanding, analysing the train of thought instead of rewarding memorisation. A proprietary algorithm drives the assessment engine under the hood.

PromptID is an AI-native EdTech platform for employers and universities that examines learners for real, in-depth understanding, analysing the train of thought instead of rewarding memorisation. A proprietary algorithm drives the assessment engine under the hood.
The Challenge
Building an AI-native assessment platform from zero is complex enough. Add a hard requirement for +1,000 concurrent users, LLM model agnosticism, and genuinely intuitive UX throughout, and the scope gets serious fast. Everything had to be production-grade from day one.
What We Did
We built the entire platform from scratch: NestJS backend, NextJS frontend, LangChain-powered LLM integration with model-agnostic architecture, Kubernetes infrastructure with up/down autoscaling, and a full observability stack, all benchmarked to +1,000 concurrent users.
Outcomes
What We Learned
LLM model agnosticism pays off fast. Clients want flexibility as the model landscape shifts and LangChain's abstraction layer made swapping models a config change, not a rewrite. Kubernetes autoscaling also proved its worth: no overprovisioning, but the system scaled up under load in seconds.
