About Me

Profile Image

As a Technical Specialist, I transformed a legacy system into a scalable SaaS capable of handling 100 million requests, designed mobile applications for a major mortgage corporation, and increased data extraction accuracy from 75% to 98% using Java Spring Boot, MongoDB, and ML models. Leading cross-functional teams, I ensured on-time project delivery and generated ~$800K in revenue. I built deployment pipelines with Jenkins, ArgoCD, and AWS, ensuring 99% uptime, and chaired meetings to improve communication and productivity.

As a Senior Software Engineer, I developed MVPs, enhanced app usability, mentored over 15 new hires, and reduced defects by 70% through static code analysis and code reviews.

Previously, as a Software Engineer, I reduced mobile app crashes by 80%, increasing user retention by 75%, and boosted user engagement by 80% through feature implementation and code refactoring.

Projects

ResNeXT - Pneumonia Detection using AI

Built a sophisticated AI model to detect any patterns from an X-ray that will increase the probability of an accurate pneumonia diagnosis. The model is currently being trained on a dataset of 5,000+ X-ray images to classify whether the person is affected.

Zootopia

Built inventory management, zoo population control, and employee management systems to demonstrate advanced Database Management skills. The backend was written in Java and had an Oracle DB as a Database System. The front end was done in both React and JavaFX.
