Architecture
Research collaboration platform architecture
Fusio(n) keeps the researcher product experience inside Laravel and Inertia, while semantic matching, realtime collaboration, queues, pgvector storage, and the companion ML API sit behind explicit service boundaries.

- AI and matching services
- Embedding generation, semantic search, hybrid boost scoring, match explanations, recommendation caches, and ML service integration.

Stage 3
Async and realtime
Longer work and live collaboration state are separated from normal page rendering.

Technical details
- Redis-backed jobs
- AI recommendation generation, entity processing, match regeneration, team recommendations, newsletters, cleanup, and operational commands.
- Reverb and Echo events
- Messages, communications, notifications, team updates, and recommendation readiness are broadcast to the React client.
-
-
Stage 4
Data and external services
Transactional data, semantic vectors, cache/session state, and heavy ML matching are kept behind storage and service contracts.
-
PostgreSQL with vector search
- PostgreSQL
- pgvector
-
Cache, AI providers, and ML API
- Redis
- OpenAI
- FastAPI ML
Technical details
- PostgreSQL with vector search
- Users, profiles, keywords, teams, communications, entity documents, embeddings, semantic matches, feedback, and recommendation state.
- Cache, AI providers, and ML API
- Redis handles cache, sessions, queues, and scaling; AI providers handle embeddings and extraction; the companion FastAPI service handles heavier collaborator ranking.
-
Key flows
-
React and Inertia UI to Laravel domain layer
Authenticated product workflows move through Laravel routes, controllers, request validation, policies, and service classes.
-
Laravel domain layer to PostgreSQL with vector search
Profiles, teams, communications, embeddings, semantic matches, and feedback are persisted in the primary database.
-
Laravel domain layer to Cache, AI providers, and ML API
Embedding, structured extraction, heavier ML matching, and workgroup analysis are called through service abstractions.
-
Async and realtime to Product experience
Jobs and events update recommendations, messages, notifications, team changes, and assistant state without requiring manual refresh.
Outcomes
Impact
- Mapped the technical architecture for researcher onboarding, profile-based discovery, semantic matching, workgroup creation, team workflows, and collaboration communication.
- Implemented AI-backed matching patterns with provider abstraction, embeddings, pgvector similarity search, hybrid scoring, and reliability controls.
- Documented production-readiness considerations for caching, queues, realtime broadcasting, observability, and operational handoff without exposing environment-specific details.
Fusio(n) is a research collaboration platform built around the problem of helping researchers and adjacent public, industry, and civil-society participants find useful collaborators, assemble teams, and coordinate work.
The project is not only a Laravel app with a React frontend. From a technical perspective it includes multiple matching paths, a profile system, AI and semantic infrastructure, collaboration workflows, real-time communication, and operational documentation.
Product Scope
The platform supports profile-driven onboarding where users describe what they are searching for and what expertise they can offer. Those profiles feed several discovery workflows:
- Hard Flow for deterministic profile and keyword matching
- ML Flow for external workgroup API powered collaborator ranking through the Research Collaboration ML Matching API
- Content Flow for research-related recommendations
- Team Science for building teams around selected keyword coverage
- Collaboration Hub for searching users, saving content, and initiating collaboration requests
- AI Bio Matching for processing research bios into structured documents, embeddings, and semantic matches
- Unified communications for messages, collaboration requests, team notifications, and live updates
The ML Flow is separated as its own service because model inference, embedding cache, batch processing, and GPU/CPU runtime concerns are different from the Laravel product runtime. Fusio(n) carries the user-facing workflow, while the companion ML API handles heavier researcher matching behavior.
Architecture
The backend is built with Laravel 12 on PHP 8.3. Inertia.js connects the Laravel routes and controllers to a React 19 and TypeScript frontend built with Vite and Tailwind CSS.
The application separates domain behavior into controllers, jobs, models, events, providers, policies, and service classes. Important technical boundaries include:
- embedding generation, caching, storage, and vector similarity lookup
- semantic search, hybrid boost scoring, match explanation, and cached results
- companion ML service integration for heavier matching and workgroup analysis
- direct messages, collaboration requests, team threads, and realtime broadcasts
- team gap analysis and user/content recommendation workflows
- operational metrics for latency, cache behavior, usage, and match quality
AI and Matching Infrastructure
The AI layer uses a provider abstraction so embedding, structured extraction, match explanation, retry, timing, and usage accounting behavior can be handled behind one application boundary.
Semantic matching is backed by PostgreSQL with pgvector. The schema stores raw entity documents, cleaned content, structured data, embeddings, cached semantic matches, match feedback, and embedding job status. The embedding table uses a vector column and an HNSW cosine index for fast similarity search.
The matching pipeline combines vector similarity with rule-based boosts. Boosts account for discipline overlap, career-stage compatibility, keyword/topic overlap, and target-specific eligibility. This makes the result more useful than plain nearest-neighbor search alone.
Real-Time Collaboration
The communication system moved beyond basic message tables into a unified thread model. It supports direct messages, collaboration requests, team threads, hub collaboration requests, participant responses, unread counts, notifications, keyword assignment actions, replacement suggestions, and coverage analysis.
Laravel Reverb and Laravel Echo provide the real-time layer. Events such as messages, communication updates, team updates, recommendation readiness, and notification changes are broadcast to the frontend so collaboration state can update without manual refreshes.
Operational Readiness
The operational design separates web serving, realtime broadcasting, cache/session storage, and queue workloads. The public case study keeps this intentionally high-level and does not expose environment names, startup automation, private application paths, or recovery procedures.
The readiness work includes:
- cache and queue separation
- realtime broadcasting boundaries
- migration and release sequencing
- configuration caching strategy
- operational notes for observability and handoff
- post-release verification checklists
Reliability work also includes abuse-prevention controls, queue planning, AI dependency health checks, performance notes, test coverage, and operational documentation.
Quality and Reliability Work
The public page avoids exposing exact protective controls or private application paths. At a technical level, the project includes:
- gated application flows
- centralized input validation
- abuse-prevention boundaries
- AI usage controls
- data minimization in recommendation outputs
- feature tests for core product behavior
- automated formatting, linting, and build checks
Technical Perspective
This case study demonstrates full-stack technical breadth rather than isolated feature work. The visible scope includes Laravel backend development, React/Inertia frontend implementation, AI matching infrastructure, data modeling, async jobs, realtime communication, performance tuning, and operational documentation.
