About

From apps to data

I started at CIMOL technical school training an AI to recognize melanomas in skin photos — the first time data and healthcare crossed paths in my career.

I then spent almost five years building full stack products: APIs in Java/Spring and Go, apps in Flutter and Next.js, data modeling on Oracle, SQL Server and PostgreSQL.

Today I'm a Data Engineer at NoHarm.ai, moving hospital data into clinical pharmacy: AWS pipelines, SQL modeling for reporting and LLM-powered text-to-SQL.

Things I've built

NoHarm.ai case · private

Clinical text-to-SQL

Clinical pharmacists ask questions in plain language; an LLM pipeline generates SQL over NoHarm's data model, runs it on PostgreSQL and returns the answer.
