About Me
I'm a Software Engineering student at SZABIST, Karachi (graduating 2027), currently working as a Data Engineer at Technocas and Backend Developer at Zank AI, a US-based fintech startup — both roles I hold simultaneously.
I specialize in building end-to-end data pipelines, scraping systems, and production backend infrastructure. From wrangling 10k+ product records out of e-commerce sites to designing Snowflake ETL workflows with Airflow — I build things that work at scale.
I'm also trained in Cloud Data Engineering at SMIT and hold an Oracle Cloud GenAI certification. Open to remote roles in Cloud Data Engineering, Backend, or AI integration.
