I successfully completed the development of an API for an online marketplace, enabling sellers to efficiently manage their products and orders through programmatic interactions. Leveraging my skills in ETL, Full-Stack Engineering, Back-end Development, Infrastructure Provisioning, DevOps, CI/CD, and Real-Time Transaction Updates, I utilized a range of tools and technologies, including Python, Docker, Azure Kubernetes Service, Azure Functions, FastAPI, Payment gateways, and VPC.

One of the key aspects of the project was implementing OAuth2 authentication with JWT tokens, ensuring secure and authenticated access for sellers interacting with the API. By incorporating this industry-standard authentication mechanism, I provided a reliable and robust layer of security to protect sensitive seller information.

Throughout the development process, I adhered to best practices in software engineering and utilized agile methodologies, allowing for efficient collaboration with stakeholders and ensuring the delivery of high-quality code within specified timelines. I emphasized clear and concise documentation, facilitating ease of use and integration for future developers working with the API.

Additionally, I leveraged the power of containerization using Docker, which enhanced scalability and portability of the application. By utilizing Azure Kubernetes Service, I orchestrated the deployment and management of the containerized application, providing a highly available and fault-tolerant infrastructure.

The API facilitated seamless management of products and orders, empowering sellers to automate and streamline their operations. Real-time transaction updates ensured that sellers were always informed about the latest status of their orders, enhancing the overall user experience and satisfaction.

Overall, through my expertise in API development, utilization of relevant tools and technologies, and emphasis on security and scalability, I successfully delivered a robust and efficient API for the online marketplace, enabling sellers to effectively manage their products and orders programmatically.
