What problem did Job Jolt have?
Applying from LinkedIn meant copying job details by hand and spending too long on generic cover letters before every application.
How did we approach it?
One-click extraction in the browser, sanitized payloads sent to a secure API, and OpenAI generation tuned for speed and relevance to the specific listing.
What did we build?
React Chrome extension injected on LinkedIn job pages; Flask backend with OpenAI; API key validation, token-based authentication, rate limiting, bcrypt password hashing, and SQLAlchemy for user and database management.
What was the outcome?
An end-to-end workflow from job listing to draft letter in seconds, an early, practical AI product that shows real browser and backend integration without overselling scope.
