Backend-focused software engineer using Python, PySpark, and LLMs to build scalable data and AI products.
IndiaWhat I'm looking for
I’m a backend-focused software engineer who builds scalable data pipelines and AI-assisted applications. At UD Trucks India, I designed and deployed ingestion pipelines with PySpark and migrated 5TB+ of Parquet data in AWS S3 to Apache Iceberg-backed tables, improving query performance and reducing scan costs by 30%.
I’m hands-on across the stack when it helps the product—like building a Flask/Vue.js reconciliation tool to automate Excel comparisons. My projects include an async YouTube-to-shorts pipeline (FastAPI, Celery, Redis, FFmpeg) and an F1 telemetry platform (FastAPI, React) with local Parquet caching and performance gains from 15s to under 100ms per session.
