What I'm looking for

I am looking for a challenging role to build scalable web applications and contribute to collaborative projects.

As a Python backend developer, I specialize in designing and building production-ready APIs using frameworks like Django, DRF, and Flask. My experience encompasses creating scalable systems with clean architecture, secure JWT authentication, and PostgreSQL databases. I take pride in delivering fast, modular, and maintainable backend code, ensuring that my projects are not only functional but also adhere to best practices.

I am certified in Python through Harvard's CS50P course and actively contribute to open-source projects. My portfolio includes a range of applications, from a Freelancer Marketplace API to a SaaS Billing API System, showcasing my ability to tackle complex challenges and deliver robust solutions. I am passionate about leveraging my skills to support real-world product development and thrive in collaborative team environments.
