What I build when nobody’s asking me to.
Full systems, designed and operated solo, in real cloud accounts I pay for myself. No sandbox, no staging environment someone else maintains, no ticket dictating scope — every decision here is one I made, deployed, broke, and fixed. Each page below covers the trade-offs, not just the diagram.
NexusIQ
A working multi-agent AI control plane: Text-to-SQL, RAG, federated query across four engines, role-based governance, and sovereign AI request classification — running end to end.
NexusRetail
A multi-tenant retail and inventory platform with AI invoice reconciliation, designed, deployed, and operated solo in a real AWS account — VPC, ECS Fargate, Cognito, Textract, WAF, and full CI/CD.
Convoy
A fleet re-optimization demo running entirely on local, no-cloud Exasol Personal — live MongoDB vehicle federation via Virtual Schema, an in-database re-optimization UDF, and an XGBoost demand model.
