About this gig
Need better recommendations, fraud detection, relationship prediction, or network intelligence?
I build custom Graph Neural Network (GNN) solutions that uncover hidden patterns and relationships in connected data.
Whether you're working with customers, products, transactions, users, entities, or social networks, GNNs can help generate more accurate predictions and deeper insights than traditional machine learning approaches.
What I build:
- Recommendation systems
- Fraud & anomaly detection
- Link prediction
- Node & edge classification
- Knowledge graph intelligence
- Customer and product relationship modeling
What you get:
- Graph data preprocessing
- Custom GNN model development
- Model evaluation and insights
- Clean documented code
- Source files and notebooks
- Optional APIs, Dockerization, and deployment support
Common use cases:
- Ecommerce recommendation systems
- Financial fraud detection
- Customer intelligence platforms
- Social network analysis
- Knowledge graph applications
- Research and graph analytics
Message me before ordering so I can review your graph structure and recommend the right approach.

FAQ
Can you work with my custom graph or CSV data?
Yes, I preprocess your graph data and build a full GNN pipeline.
Can you build network graphs to show relationships or collaborations?
Yes, I build domain-specific network graphs to visualize and analyze relationships, interactions, and collaborations.
Can you build recommendation systems using knowledge graphs?
Yes, I design GNN-based recommendation systems using knowledge graphs tailored to your data and goals.
Can you build an author collaboration graph from my CSV data and then apply GNN for analysis?
Absolutely! Share your co-authorship CSV (e.g., author A, B, publication ID), and I’ll build a graph, extract features, apply GNNs (GCN, GraphSAGE) for clustering or link prediction, and deliver visualizations + ready-to-use PyTorch Geometric code for research.
I have a general network graph in CSV format—can you process it and build a full GNN pipeline?
Yes! Just upload your edge list CSV (with optional node features), and I’ll preprocess it, build a GNN (GCN, GAT, etc.) for your task, train & evaluate it (accuracy, ROC-AUC, etc.), and deliver clean code, scripts & visualizations—perfect for research or deployment.
Is this suitable for production or real use cases?
Yes, the solutions are designed for real-world and scalable applications.
Do you provide inference or deployment support?
Yes, I deliver Docker or API-ready inference pipelines for easy integration and deployment.
