The Human Intelligence Behind Artificial Intelligence.

I bring the precision of a Banker, the logic of a Coder, and the insight of a Psychologist to ensure your software works for you.

Beyond The Code

I don't just find bugs; I find the "why" behind them. I am a Senior QA Engineer who bridges the gap between cold logic and human behavior.

Full-Stack Quality

14 years of navigating the entire SDLC. From the first line of code to the final deployment, I ensure your product is robust, scalable, and ready for the real world.

The Psychology of Users

Code doesn't exist in a vacuum. My Psychology background lets me predict how users actual behavior, catching critical design flaws that automated scripts miss.

Financial Precision

In Fintech, a decimal point is a disaster. My 5-year Finance & Banking degree means I speak the language of business, ensuring your logic is as sound as your code.

Elite Technical Services

Specialized expertise for companies that cannot afford to fail.

AI Reality Check

AI & LLM Validation that separates hype from reality. I test your models for factual accuracy, logical consistency, and safety, ensuring they deliver real business value.

Intelligent Automation

Stop maintaining brittle scripts. I build resilient Test Automation Frameworks (Python, Playwright) integrated into CI/CD that adapt to change and speed up your releases.

The Technical Truth

Hiring is hard. As a Technical Verification Specialist, I cut through the resume noise. I conduct rigorous technical interviews to tell you exactly what a candidate knows—and what they don't.

Proven Results

Real problems solved. Real value delivered.

Taming the LLM

Benchmarked and optimized an AI chatbot for a 30% increase in accurate responses.

Fortifying Fintech

Led security and functional testing for a high-volume banking platform, achieving zero critical defects in production.

Automation Evolution

Migrated legacy manual tests to a modern Python framework, cutting regression time from days to hours.

Let's Talk Quality

You need more than a tester. You need a partner who understands the code, the business, and the user.
