Owned backend and database development for a data-intensive SaaS platform built from scratch, contributing to architecture decisions. Designed PostgreSQL data models, indexes, constraints, and migrations for systems handling millions of records. Applied Django ORM optimizations and shaped TimescaleDB hypertables and time-series aggregation workflows. Built CSV and data-processing pipelines with bulk operations and asynchronous execution, and delivered REST APIs feeding frontend charts and tables. Orchestrated background processing with Celery and Redis, improved performance through caching and query optimization, achieved 95%+ automated test coverage, and processed 1 million+ source rows for a single object. Collaborated via Git Flow, GitHub Actions, code reviews and architecture discussions.
