Computer science student at Lakehead University. Two systems I architected are live in production at a startup — Django, Celery, FastAPI, PostgreSQL with pgvector. I film the work most days and publish it.

Worked on ticket class and tests. Completed them. Pending comment class and employee class.
continued working on Ticket class and testing, need to improve.
I started coding this project, wrote few tests, and started implementing the ticket class. Thank you for following along.
Hi guys, it's been some time. I came back to this project today. I was involved in hackathons, and work got little tight. I will try to stay consistent moving…
About Me
Prajith Ravisankar
Hons. BSc in Computer Science
I work on backends: multi-tenant Django integrations with OAuth and webhook verification, Celery pipelines that survive duplicate deliveries, and a FastAPI service doing semantic search over 14,000+ ad-targeting options with pgvector. Two of those are live in production. I am finishing a CS degree at Lakehead University, and I film most of the work and put it on YouTube — currently Day 28.

PythonDjangoDjango REST FrameworkCeleryJavaScriptReactReduxPostgreSQLRedisAWS S3WebSocketsREST APIsOAuth 2.0Ad Platform APIsGit- Worked with four Engineering Interns to build OAuth 2.0 authentication for six advertising platforms using Django, Redis, and REST APIs, improving token handling to prevent authentication issues and improve platform reliability.
- Built a real-time deployment status feature using React, WebSockets, and Redis, replacing polling and giving 60+ businesses live progress updates and failure notifications across multiple active deployments.
- Worked with the Founding Engineer on an AWS S3-based media pipeline that automatically resized uploaded assets for the requirements of six advertising platforms, allowing one upload to be reused across platforms.

- Designed a PostgreSQL-based targeting taxonomy that organized 14,000+ targeting options across six advertising platforms, enabling businesses to discover similar audiences across platforms through a unified system.
- Improved search performance with specialized database indexes, achieving sub-100ms filtered queries and sub-500ms semantic search results across all six advertisement platforms; now live in production.
