Services
01
Technical Research
Compare graph technologies, standards, and architectural options before committing to a tool or PoC.
02
Data Modeling & Review
Review graph data models, RDB-to-graph mappings, schemas, and relationship semantics before implementation.
03
GraphRAG Architecture
Design practical GraphRAG architectures around retrieval, context, provenance, and evaluation.
04
Migration Planning
Use graph modeling to clarify dependencies, inconsistencies, encoding issues, and cutover risks in system or data migration.
05
Internal Training
Run focused sessions on graph databases, knowledge graphs, GraphRAG, Cypher, SQL/PGQ, and GQL.
I help teams turn complex relationships, data dependencies, and migration risks into practical graph models — for search, analysis, migration planning, and knowledge systems that need reliable context.
