Project details

I’m a Backend Engineer, Data Engineer, and System Architect with 4+ years of experience building scalable backend systems and data pipelines for internal tools and data-driven applications.

I specialize in system architecture, backend development, data engineering, and cloud infrastructure, delivering reliable, performant, and production-ready solutions.

Expertise includes: scalable APIs, Python backend development (Django, DRF, FastAPI, Flask), data pipelines and ETL, relational and analytical databases, efficient ORM queries, third-party API integrations, Docker, CI/CD pipelines, and cloud deployment on AWS and Google Cloud.

You’ll get clean, well-documented code, scalable designs, reliable data flow, automated deployments, and clear communication.

If you need someone to design, build, and deploy scalable backend systems, I’d be happy to help.
