Worked on enhancing patient allergy data integrity within the ntu-pear/PEAR_WebFE repository by updating the patient allergy update endpoint to utilize patient_allergyid, replacing the previous patientId approach. Extended the AllergyUpdateFormData structure to include PatientID, ensuring more comprehensive and accurate data capture for each update. These changes improved the reliability of patient allergy records, supporting more accurate downstream analytics and clinical decision-making. Coordinated closely between frontend and backend systems to reinforce data consistency across the application. Leveraged React for front end development and utilized both JavaScript and TypeScript to implement these enhancements, focusing on robust data handling and system integration.
