Top SchoolSubhayu Bala is a data and infrastructure engineer with six years’ experience building high-performance data systems and production AI/LLM pipelines, currently driving ingestion, onboarding, and observability at Loop AI. He has a track record of dramatic optimizations—replacing a 27.5-hour SQL job with a 5-second DuckDB/Pandas engine on 80M+ records and cutting BigQuery scans from 342 GB to under 6 GB—while architecting the data platform behind a startup’s $6M Series A. At FiftyFive Technologies he delivered enterprise-grade solutions for clients like Johnson & Johnson and Advent International, built TB-scale deduplication tooling later open-sourced with 9.7k+ downloads, and automated logistics workflows that replaced dozens of manual ops. He combines hands-on systems work (Python, SQL, dbt, Kafka, Airflow, cloud platforms) with production AI—fine-tuning LLMs on H100 clusters and shipping agentic systems with >95% task accuracy. Based in Kolkata, he also maintains six Python packages on PyPI with 43k+ downloads and has published research in quantum communication, reflecting a blend of practical delivery and academic curiosity.
