Back End Developer at SEO Quartz who engineered secure REST APIs and optimized MongoDB queries for faster performance.

At SEO Quartz, I engineered secure RESTful APIs with Node.js and Express.js for authentication and data processing.

I designed MongoDB schemas and aggregation pipelines with Mongoose, and indexed queries to improve performance. I also built JWT authentication and authorization workflows, with password hashing using bcrypt.

I tested APIs with Postman and Jest, collaborated with the React frontend team, and optimized asynchronous operations while debugging backend bottlenecks.
