✨ Chidubem Celestine Nwabuisi (DCN) ✨

Building production-grade data systems with a software engineering mindset.

🚀 About Me

I am a Data Engineer with over 5 years of industry experience in software and application development, primarily in the telecommunications sector. I specialize in bridging the gap between application code and data infrastructure.

Unlike traditional ETL developers, I apply Software Engineering and DevOps best practices (CI/CD, automated testing, version control) to build scalable, self-healing data pipelines and enterprise integrations.

Currently, I am expanding my expertise in secure data systems by researching Differential Privacy in LLM API Interactions as part of my MSc in Cybersecurity Technology.


🛠️ Core Tech Stack

Data Engineering & Backend - Python (FastAPI, Django), SQL, Apache Spark, Bash

Cloud & Orchestration - AWS (S3, Lambda, Redshift, Glue), Apache Airflow, Docker, Kubernetes, Terraform

Databases & Storage - PostgreSQL, MongoDB, MSSQL, ElasticSearch, Firebase

Software & DevOps Practices - CI/CD Pipelines, GitHub Actions, Jenkins, Secure SDLC, API Design


🔭 What I'm Working On

  • 🧱 Data Engineering Architecture: Expanding my modern data stack toolkit at ALT School Africa.
  • 🏘 Property Management Platform: Engineering the backend architecture and data models using FastAPI, PostgreSQL, and Firebase.
  • 🤖 OutBound AI (HNG 12): Collaborating on API integrations and data flow for AI-driven applications.
  • 🔐 Academic Research: Evaluating data privacy and security in LLM environments.

👯 Looking to Collaborate On

  • 🧠 Building robust data platforms and ETL/ELT pipelines.
  • 🛠 Applied Data Science and Analytics infrastructure.
  • 📦 Backend API development and SaaS product architecture.
  • 🌍 AI/NLP projects involving local African languages.
