Built a MySQL DB from scratch for the purpose of serving football stat api

A scalable real-time chat backend built with FastAPI, Redis, and Celery. It supports one-to-one and group chats, offline message persistence, user tracking through Redis, and rate limiting with a sliding window algorithm. The system uses Celery tasks queue for throttled email notifications and maintains partitioned PostgreSQL message tables.

Judicious Graph Partitioning

Composing deployment structures of a serverless application by partitioning the nodes of the service tree

Minimal library that enables partitioning of iterable collections in a concise manner.

Optimized PySpark jobs by analyzing query execution plans and rewriting transformations for efficiency. Applied techniques such as reducing shuffles, tuning partitions, selecting efficient operators, and choosing optimal data formats. Demonstrates performance tuning for large-scale Spark ETL workloads using Python and PySpark.

This project demonstrates key PySpark performance optimization techniques using a synthetic banking transactions dataset (~5,000 records). Built using Databricks and Delta Lake.

A collection of Python scripts to facilitate the preprocessing of input sequences to dynamic homology.
