Practical training, careful review, and migration support

Training, review, and migration support that help teams build capability, clarify architecture decisions, and make delivery risks visible.
日本語・英語どちらでもご相談いただけます。

Getting started

Start with the actual problem and the material you already have.

The first step is to understand the team, system, and constraints as they are. A rough architecture sketch, data sample, proposal, migration mapping, or list of concerns is often more useful than a polished presentation.
完成した提案書や要件定義書がなくても、構想メモ、構成図、データ例、移行上の懸念などから始められます。

Technical briefing for decision-makers or project teams
Enterprise training session
Project-based workshop or use-case assessment
Data model or architecture review
Migration and validation support
Ongoing technical advisory

Recommendations are based on the project, the data, and practical experience—not a commitment to one product or platform. I work in Japanese or English with teams in Japan and overseas.

Enterprise Training & Workshops

企業向け技術研修・案件ワークショップ

Focused sessions for engineers, architects, consultants, and delivery teams. Content is adapted to the audience and can range from a technical briefing to a project-based workshop. The objective is to help teams judge when a technology is useful, understand its limits, and apply the learning to real delivery decisions.

システムインテグレーター、コンサルティング会社、企業の技術チーム向けに、技術を単なる製品説明にとどめず、実際の案件で判断・活用できる研修やワークショップを日本語・英語で提供します。

Typical outcome

Shared terminology, stronger technical judgment, and a concrete way to apply the learning to a real project.

Typical focus

Knowledge graph and GraphRAG fundamentals
Graph data modeling and architecture
Neo4j, Cypher, SQL/PGQ, and GQL
Use-case assessment and PoC planning

Data Modeling & Architecture Advisory

データモデリング・アーキテクチャ支援

Independent review and advisory for graph data models, RDB-to-graph mappings, knowledge graph and GraphRAG architectures, ontology or schema choices, and retrieval design. Particular attention is given to identity, relationship semantics, provenance, implicit assumptions, and the boundaries between relational, graph, and vector systems.

構想段階、PoC前、設計中のいずれでも、IDの扱い、関係の意味、出典、暗黙の前提など、後から問題になりやすい部分を丁寧に確認します。

Typical outcome

Clear findings, visible assumptions and risks, and practical options for the next design or procurement decision.

Typical focus

Identity, relationship semantics, and provenance
Knowledge graph and GraphRAG architecture
Roles of relational, graph, and vector technologies
Second opinions on proposals and PoC designs

Migration, Validation & Technical Advisory

移行・検証・技術支援

Support complex system and data migrations through dependency modeling, data mapping, reconciliation, consistency validation, character encoding analysis, and cutover planning. This work is often less visible than a new architecture, but it frequently determines whether a migration or integration succeeds. Advisory can also cover product research, standards, interoperability, provenance, and cross-system questions.

依存関係、不整合、文字コード、対応表、検証条件、切替リスクなど、目立ちにくくても成否を左右する部分を整理します。

Typical outcome

A clearer risk picture, explicit validation criteria, and actionable findings for implementation or procurement.

Typical focus

Dependencies across legacy and new systems
Data mappings, relationships, and consistency
Character encoding, validation, and cutover risks
Standards, interoperability, and ongoing advice

Next step

Discuss your team or project.

Share a short description of the current situation, the decision ahead, or the capability you want to build.
