What I'm looking for

I’m looking for a health-tech team where I can build secure API automation, collaborate across codebases and docs, and apply medical AI curiosity to improve reliability and user safety.

I’m a software tester with a background in medicine and medical AI development. I bring hands-on experience in manual and automated API testing, security testing, and building test infrastructure for health-tech platforms.

At BalanX Bio, I reviewed and documented AWS cloud architecture for an AI health coaching platform, then executed 400+ manual API tests across multiple endpoints and produced structured test checklists. I built an automated testing sandbox using TypeScript and Jest, reverse-engineered and formalised the Layer12 WebSocket schema into a versioned contract, and documented critical security issues including a chat isolation vulnerability plus XSS/SQL injection flaws. I also coordinated cross-functional check-ins and mentored a junior intern on API testing.

As a freelance developer, I’m building an AKI prediction model using XGBoost and LightGBM, integrating SHAP for model explainability to support clinical decision-making. I enjoy working across codebases, documentation, and remote collaboration—turning reliability and security into measurable outcomes.
