I’m Afzal Hussain, a software and data engineer focused on building reliable backend services and end-to-end data pipelines. I work across Python (Django, FastAPI, Flask), SQL, and modern data engineering practices like ETL/ELT and Raw → Curated → Gold transformations to turn messy inputs into trusted datasets for analytics and production workflows. I also enjoy applying AI to real-world data tasks—preparing training/evaluation data, validating benchmarks, and helping teams build LLM/RAG solutions using tools like LangChain and OpenAI. Whether it’s cloud infrastructure on AWS, Docker/Kubernetes deployments, or CI/CD automation, I aim for scalable systems, clean data quality, and dependable delivery—often working independently on remote, project-based engagements.…I’m Afzal Hussain, a software and data engineer focused on building reliable backend services and end-to-end data pipelines.
