I design and build software, data architectures and intelligent solutions for real problems.
01 / APPROACH
I think in complete systems.
From the interface to the database; from the pipeline to the process that uses it. I work across layers so each decision makes sense in the whole system.
INTERFACESAPIsDATAINTEGRATIONSAIOPERATIONS
02 / DISCIPLINES
Three disciplines. One way of building.
Data with structure and purpose.
Pipelines, models and analytical layers that make information usable.
SQL · PYTHON · PARQUET · ORCHESTRATIONIntelligence integrated into the process.
Models, tools and automations connected to concrete needs.
LLMs · WEBHOOKS · ASYNC WORK03 / SELECTED WORK
Work in context.
Technical pilots and concepts are labeled by their actual status.
