I’m a back-end focused Python engineer with about 4 years of experience building and scaling REST APIs and distributed systems in fast-paced startup environments. I’ve worked on production-grade features end-to-end—from design and implementation to deployment—especially around digital onboarding and critical fintech workflows. I enjoy performance optimization and reliability work, including database query tuning, eliminating N+1 issues, and building async processing pipelines with Celery and Redis. I also partner closely with cross-functional teams to deliver secure, test-covered services using Django/Django REST frameworks, PostgreSQL, JWT/RBAC-based access control, and CI/CD practices for consistent releases.
