BEHIND EVERY LINE
OF CODE, THERE
IS A BUILDER.
I build APIs, AI integrations and data-driven systems.
EDUREPO ↗Knowledge, organized.It starts with a foundation.
Keep contracts consistent as the system evolves.
History records my contribution propagating execution context along a feature’s path from handlers through services and repositories. Request context is passed as the first argument in corresponding interfaces and operations.

From concept
to code.
Three perspectives on engineering: applied AI, deterministic data and asynchronous market systems.
Give ideas a structure.
Knowledge needs versions, permissions and history.
EduRepo organizes academic work as versioned repositories. Titles, abstracts, institutions, authors, advisors and attachments form a structure that needs to evolve without losing history.

From information to structure.
From PDF methodology to a verifiable strategy specification.
StratHUB explores how trading methodologies described in documents can become explicit, verifiable rules. PDFs can mix explanations, charts and entry, exit and risk criteria; that information needs structure before another system can consume it.

Events become state.
Explainable market data, reproducible state.
Argus investigates the technical foundations of a market-analysis platform: receiving events, representing an order book, preserving data provenance and reproducing state later. Its central question is how to trust a data sequence before building visualizations or decisions on top of it.

The person behind the build.Isaac
Valeriano.
Engineering connects my two ways of seeing the world: Economics and Data Science. I build software to turn questions into systems we can understand, test and improve.
