Hello, Client.
I appreciate the opportunity to submit my application for this position.
I am a skilled full-stack developer with extensive experience in building secure and scalable web and kiosk-based applications.
→ In a recent project, I developed a kiosk-based application for a parking management system running on Ubuntu OS. The application targeted two user groups: admin users to manage parking registrations and customers to pay parking fees. My responsibilities included designing secure login/logout functionality with role-based access control, creating a user-friendly frontend for customers, and integrating it with a payment terminal for seamless transactions. I implemented the backend with SQL for efficient data management and ensured encryption of sensitive data at rest and in transit. One notable feature was the integration of a Pax A920 payment terminal, where I handled API communication for secure card transactions and receipt printing, ensuring a smooth user experience.
I have expertise in:
→ Frontend: React.js, Vue.js, HTML5, CSS3, JavaScript.
→ Backend: Node.js, Python (Flask/Django), Express.js.
→ Database: MySQL, PostgreSQL, SQLite.
→ Security: Role-based access control, OAuth2, SSL/TLS encryption.
→ Payment Integration: Pax A920, Stripe, PayPal APIs.
→ OS Environments: Ubuntu/Linux systems for kiosk setups.
I am confident in my ability to bring your vision to life based on my above skills and experiences.
Best regards, Jesse F.
