Heitor de Castro Teixeira

Analytics Engineer | Data & AI
Fortaleza, CE, Brasil

From Civil Engineering to Data & AI, I design end-to-end data solutions: from raw ingestion and analytical modeling to machine learning, LLM integrations, and real-time dashboards.

Repository Prefixes

To keep my GitHub organized, I use the following repository prefixes:

  • PROJ — applied projects and professional work
  • MBA — academic work from my MBA
  • TRN — training, exercises, and study-oriented repositories
  • CRS — courses and workshops I have taught

Tech Stack

Data Engineering & Analytics Python SQL dbt Airflow PostgreSQL SQL Server

Visualization & BI Grafana Power BI

Featured Projects

🔄 Acme Data Pipeline — End-to-End ELT (SAP B1 → Power BI)

End-to-end ELT pipeline (anonymized production project) that turns SAP Business One and SharePoint data into a tested, documented data warehouse on SQL Server. Four components: DB-to-DB SAP ingestion (linked server + SQL Server Agent, incremental strategies), a two-way SharePoint connector over Microsoft Graph, the dbt warehouse (medallion / Kimball, ~450 tests, Elementary observability), and Airflow orchestration. 🔗 Repository

☀️ Nexus Grid — Solar Energy Observability Platform

Data platform and dashboards for photovoltaic plant monitoring. Built analytical layers with dbt (RAW → STG → INT → MART), documented business rules, and delivered real-time operational dashboards with Grafana and PostgreSQL.

🦴 Bone Age Estimation (X-Ray AI)

End-to-end ML model for bone age estimation from wrist radiographs. Includes sex embedding for physiological differentiation, data augmentation, and validation with medical specialists. Research published at CBIS 2024. 🔗 Paper · Coverage

🏆 Fall Prevention (IoT + ML + Embedded, 2nd Place National IoT Award)

Full-stack IoT system for elderly fall prevention. ESP32 firmware for real-time sensor data collection, ML pipeline for predictive modeling, and on-device inference. Awarded 2nd place in a national IoT competition. 🔗 Coverage

🔥 Pellis, Burn Classification

Technical lead on a burn classification system using SAM (Segment Anything Model) for pre-classification noise reduction. Built the full data cleaning pipeline, including duplicate image detection and removal. 🔗 Coverage
