Hi I can support your EHR web platform by integrating and testing RESTful APIs while validating secure patient and clinical data exchange between systems. I have experience with REST API integration, Postman, Swagger/OpenAPI, API test planning, regression testing, React Native/mobile workflows, healthcare web platforms, and structured QA reporting. The main technical challenge is ensuring patient, appointment, clinical, and workflow data remains accurate and secure across API-connected modules. I will solve this by creating clear API test cases, checking request/response payloads, validating edge cases, confirming authentication and permission behavior, and reporting defects with reproducible steps. I can also verify FHIR/HL7-style data structures where applicable, test mobile and web flows connected to the APIs, and support backend/frontend teams during issue resolution. My focus will be reliable test coverage, clean communication, and preventing healthcare data integrity issues before they reach production. I can work within your existing QA process and provide simple, actionable reports for the development team. Thanks, Hercules

Hello, I hope you're doing well! I understand you need an API Integration and Testing Engineer to support an EHR platform by validating RESTful integrations, verifying healthcare data exchange, ensuring patient-data integrity, and performing comprehensive functional and regression testing across connected systems. I have strong experience with REST APIs, Postman, Swagger/OpenAPI, integration testing, QA workflows, backend validation, and data-driven applications, including working with structured healthcare-style data exchanges and detailed defect reporting. I will thoroughly test API endpoints, validate request/response accuracy, verify workflow integrity across systems, document findings clearly, and collaborate closely with the development team to ensure reliable, secure, and compliant integrations. Q1: Which healthcare standards are currently in use—FHIR, HL7, or a custom data model? Q2: Do you already have API documentation and test environments available for validation? Q3: Is the primary focus on backend API testing, or do you also require end-to-end testing involving the web/mobile applications? Looking forward to helping strengthen the quality and reliability of your EHR platform!

Hi, The core of this is verifying patient and clinical data integrity as it moves between systems, and that's where most EHR integrations break: a FHIR resource that validates in isolation but drops fields on the round-trip. Testing API endpoints against the contract, not just the happy path, catches that. How I'd approach it: - Postman + Newman for automated REST API suites that run in CI - Swagger/OpenAPI as the schema-validation source - Targeted checks on FHIR or HL7 payloads, plus functional and regression testing per endpoint I work across Node.js backends and React Native, with a 5★ rating over 72 reviews here for careful shipping — which counts for more when patient data is involved. Are you hitting a FHIR server (HAPI, Azure API for FHIR) or a custom REST layer mapping to HL7 v2? That shifts the validation strategy. Asif

I’ve worked on integrating and testing RESTful APIs for healthcare platforms before, focusing on verifying accurate data exchange and secure workflows. For a similar EHR project, I tested endpoints to ensure patient and clinical data integrity aligned with HL7 standards, catching issues early through functional and regression tests. I can use Postman and Swagger to validate your APIs efficiently and provide clear, detailed reports on any problems. To prepare, could you share whether your APIs follow FHIR or HL7 formats primarily? Also, do you have existing automated tests, or would you need help setting them up? I’m ready to jump in and help ensure your EHR platform runs smoothly with reliable, secure API integrations.

I've seen EHR integrations return 200 responses while silently mapping clinical fields to the wrong patient records. By the time anyone notices, the data is already inconsistent and hard to trace back. I've done production API integration on a trading platform with real-time broker APIs (Kite, Angel One) where data accuracy wasn't optional. Same principle applies here: validate payload structures, test edge cases before they become data issues, document failures so the dev team can act fast. I'd start by auditing your endpoints in Postman, map responses against your FHIR or HL7 schema, and run functional and regression tests across patient and clinical data flows. Are your API contracts currently FHIR R4 or custom REST, and is there an existing schema definition I can work against?
