At Profit Development Company, I develop full-stack applications with Python, React, and PostgreSQL. I implemented role-based access control and JWT authentication, and built REST APIs with Django Ninja.

I also processed CSV data with Pandas and generated automated PDF reports with FPDF. I write unit and integration tests for business logic, APIs, and application workflows.

On a freelance project, I developed and maintained a large property management SPA with React and TypeScript. I built reusable UI components and configuration-driven forms, and integrated REST APIs with caching, authentication, and automatic token refresh.
