Training Marketplace Platform Development for Enterprises

About the client

A UK-based EdTech company operating in the corporate training sector, building a scalable SaaS platform to connect training providers with global enterprise buyers through AI-driven search and real-time availability.

The Story

The client approached FiftyFive Technologies after validating their MVP. The prototype proved market demand but lacked scalability, AI intelligence, and enterprise-grade architecture. FiftyFive was engaged to design, develop, and deliver a full SaaS build, ensuring AI-powered matching, real-time data handling, and enterprise security. The goal was to establish a transparent, global marketplace connecting providers and buyers directly while maintaining compliance and scalability.

Challenges

• > Two-sided marketplace onboarding and engagement for buyers and providers.

• > AI-driven natural language search with domain-specific accuracy.

• > Real-time provider availability and large-scale traffic management.

• > Metadata-driven course ranking, deduplication, and ML-based recommendations.

• > GDPR compliance with enterprise authentication/authorization.

• > Delivery of a full-scale SaaS build within nine months.

The Solution

• > Architecture & Infrastructure: Microservices on AWS ECS + Lambda; Node.js (TypeScript) backend with GraphQL APIs; Next.js + Tailwind frontend.

• > Database Layer: PostgreSQL (transactions), Elasticsearch (search), Redis (real-time caching).

• > AI/ML: BERT-based embeddings, domain-specific NLP pipeline, ML-based ranking integrated with Elasticsearch.

• > Core Features: Buyer AI + structured search, secure booking/messaging, provider dashboards with analytics, multi-region/currency support, GDPR-compliant policies.

• > Engineering Team: 12-member cross-functional team including backend, frontend, AI/ML engineers, UI/UX designers, and QA, delivering in Agile 2-week sprints.

• > DevOps & Security: GitHub Actions + CodePipeline CI/CD, JWT + AWS Cognito authentication, KMS encryption, CloudWatch + ELK observability.

The Outcome

The platform was delivered in 8.5 months, benchmarked to handle 100k+ concurrent users with <200ms response times. 78% of buyers adopted AI-driven search over structured queries, validating the NLP engine. Over 1,200 providers onboarded in the first six months, including many previously absent from search engines. The client gained a competitive edge as the world’s first free-to-use corporate training marketplace, expanding rapidly across UK, EU, and ME markets, strengthening both revenue potential and global market goodwill.
