Problems We Aim to Solve

#1

Scattered Opportunities

The job market in Tunisia is fragmented: offers are scattered across dozens of platforms with no unified view.

2. Integration

Difficult Integration

Graduates struggle to find PFE topics, internships, or jobs matching their profile.

3. Fragmentation

Isolated Career Tools

No single solution covers search, CV, interviews, and training end-to-end.

4. Visibility

Recruiters Lacking Visibility

Companies struggle to identify the best candidates among applicants.

Stack & Architecture

05 · Architecture

Why Microservices?

General benefits of splitting a monolith into services

Monolith vs Microservices

Scalability

  • Scale only the services under heavy load
  • Add capacity where demand grows, not across the whole app

Independent Deployment

  • Release, patch, or roll back one service at a time
  • Each service can use the language, runtime, and infrastructure best suited to its workload

Loose Coupling

  • Clear boundaries between business capabilities
  • Failures and refactors stay contained within a service

Database per Service

  • Each microservice owns its private data store
  • Teams evolve schemas without cross-service table coupling

05 · Architecture

Microservices Architecture

React Client API Gateway Users CV Portfolio Jobs Projects Scraping Notifications AI Service Internal only RabbitMQ HTTP internal HTTP internal

Portfolio ↔ Users (internal resolve) · Jobs ↔ AI · CV ↔ AI · Scraping → RabbitMQ ← Jobs · Notifications

05 · Stack

Full Technology Stack

Glybette global runtime architecture: frontend, API gateway, microservices, RabbitMQ, MongoDB, and technology stack

05 · Deployment

Deployment Tooling

Why Glybette standardizes on containers and an automated pipeline

Docker

One reproducible runtime for every microservice on the VPS.

  • Compose orchestrates the full Glybette stack: gateway, services, MongoDB, RabbitMQ, Redis
  • Same image boundaries in dev and production; each sprint ships an isolated service build
  • Environment injected at deploy time; no secrets baked into images

Jenkins

Automated CI/CD on the VPS, from Git push to live rollout.

  • Pipeline triggered on main: checkout, env injection, preflight, deploy, smoke tests
  • Production .env stored in Jenkins credentials, never committed to Git
  • Fits the Scrum cadence: every sprint ends with a verifiable, repeatable deployment

Why Scrum?

3 releases 9 sprints 1 service / sprint
Plan
Build
Review
Retro

Each sprint cycles through ceremonies, then ships one microservice

01

Fit for Microservices

  • Each sprint = one microservice end-to-end
  • Services map naturally to sprint boundaries
  • Incremental integration, no big-bang deploy
02

Sprint Cadence

  • 3 releases × 3 sprints = 9 total
  • Plan → Build → Review → Retro
  • Continuous supervisor feedback
03

Feedback Loop

  • Weekly demos to enterprise & academic supervisors
  • Backlog refinement between sprints
  • Retrospectives drive process improvements
