Strategic Multi-Site ERP Transformation

Enterprise ERPFinanceMaterialsProductionPayrollB2B Integration

24 modules across two independent entities

A large ERP implementation spanning two nearby but independently managed sites, with a 25-engineer delivery team. The architecture covered core enterprise functions including finance and accounting, materials, sales and distribution, production, equipment maintenance, personnel, payroll, security and project information.

Relational Data ModelJava Web EngineTransactional ServicesExtension FrameworkSecurityEnterprise Integration

The architecture treated ERP as the digital backbone of the enterprise rather than a set of isolated modules. Shared financial impact, reusable services, common standards and extensibility were central concerns.

The project combined site leadership, enterprise process understanding, architecture, implementation discipline and the development of a young engineering team.

Identity as an integrated enterprise system

A practical reference architecture integrating Spring Boot 3, Spring Security 6, Keycloak 26, Okta SAML 2.0 and Just-In-Time provisioning. The focus is not on isolated protocols but on authentication, federation, provisioning and lifecycle behavior working as one enterprise IAM system.

Procurement Analytics Chatbot Architecture

ProcurementAzureData LakeGenerative AIFinOps

Databricks for transformation; lightweight serving for questions

A procurement analytics proof of concept using ADLS Gen2, Databricks Delta Lake, DuckDB, Python Flask and Anthropic Claude. Business users ask questions in English; the application generates and validates SQL, queries curated Gold Delta tables, and returns an explanation in business language.

Databricks performs transformation and prepares Gold tables, but it does not need to remain continuously active for chatbot serving. DuckDB can query the curated data directly, reducing always-on compute and making cost part of the architecture decision.

Architecture MethodProduction EngineeringGovernance

AI must live inside the enterprise nervous system

The recurring architecture principle across these projects is that AI does not repeal enterprise engineering. IAM, security, observability, DevSecOps, data governance, FinOps, compliance and production operations remain part of the architecture.

Security and identity are designed in, not bolted on.

Observability and auditability are architecture components.

Cost and runtime economics influence design choices.

Human accountability remains explicit for consequential actions.
