What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth in a dynamic environment.

As a Senior Python Developer with over 11 years of experience, I specialize in developing scalable web applications, automation solutions, and data-driven systems. My expertise lies in frameworks such as Django, Flask, and FastAPI, along with cloud deployment on AWS, Azure, and GCP. I have a proven track record of optimizing database performance and implementing CI/CD practices to enhance the efficiency of modern distributed systems.

Throughout my career, I have successfully designed and developed high-performance REST APIs, managed asynchronous processing pipelines, and migrated legacy applications into modular microservices. My commitment to security and compliance has led me to build robust authentication mechanisms and role-based access control systems. I take pride in mentoring team members and fostering best practices in software development, which has significantly improved productivity and code quality within my teams.
