What I'm looking for

I’m looking for a backend-focused role where I can build reliable REST APIs and data pipelines, collaborate cross-functionally, and keep improving quality through testing and automation while growing as a developer in an Agile environment.

I’m a Python Backend Developer with ~1.4 years of experience building RESTful APIs, server-side services, and data pipelines for production-grade logistics applications. I focus on clean, maintainable Python code, strong API integration, and reliable database management to deliver backend features that work in real-world workflows.

In my current role, I designed and built FastAPI REST endpoints and improved performance through query optimization, while also developing a text-to-SQL backend module to help non-technical users retrieve structured data via natural language. I’ve also refactored legacy backend components, built data processing scripts for logistics datasets, and supported smooth integration between React/TypeScript frontend and backend APIs. Previously as a QA Trainee, I executed Postman API tests and automated regression scenarios using Python and Selenium, partnering with backend developers to triage defects across multiple release cycles.
