Joy Sebastian C.

A digital product can function technically while remaining incomplete with respect to business needs, difficult to use, or insufficiently tested before its release.

I help companies validate the functionality of their websites, applications, SaaS platforms, data, and AI-generated content.

My approach connects three dimensions: business requirements, user experience, and execution quality.

I can assist with:

• Analyzing needs and clarifying requirements;

• Drafting scenarios, test cases, and acceptance criteria;

• Manual testing, functional acceptance, and UAT;

• Regression testing after fixes or updates;

• Identifying and documenting defects;

• Benchmarking AI responses or content;

• Annotating, classifying, and quality controlling data;

• Analyzing KPIs and performing Excel/SQL checks.

I use prompting and AI tools to improve test coverage, search for edge cases, structure needs, and accelerate documentation. AI remains an assistance tool: results are systematically checked against guidelines, user context, and quality criteria.

My background in finance, SaaS, and digital operations has provided me with rigor, traceability, confidentiality, and the ability to collaborate with technical and business teams.
