Experience
EKIMO
A comprehensive healthcare platform designed to streamline various aspects of patient care. The system allows users to search for and book doctors' appointments, purchase medications, and manage referrals and prescriptions all in one place.
As the lead architect, I designed and implemented the entire back-end infrastructure using Ruby on Rails, supported by AWS services for scalability and reliability. The platform integrates with multiple 3rd-party systems and ensures the secure handling of sensitive medical data.
EKIMO has significantly improved the efficiency of healthcare service delivery, providing patients with a seamless experience and healthcare providers with robust tools for managing their operations.

Healthcare System for Hospitals
This healthcare system was developed to optimize hospital patient and medical chart management. The platform supports patient registration, appointment scheduling, and comprehensive medical chart documentation, thereby improving hospital workflow efficiency. I was responsible for creating the system architecture, using Ruby on Rails and PostgreSQL to handle large volumes of sensitive medical data while ensuring data security and regulatory compliance. The system also integrates with external services for lab results and referral management. As a result, it reduced patient processing time by 40% and improved overall data accuracy, thereby enhancing hospital performance.
MultiChannel Banking Platform
The MultiChannel Banking Platform was designed to modernize and enhance the digital banking experience for Bank Republic’s customers. I led the redesign and implementation of both mobile and internet banking features, focusing on improving user experience and system performance. The project also included a shift to an enterprise service bus (ESB) architecture using Tibco, which enhanced the platform’s scalability and transaction processing speed. These efforts resulted in a more seamless banking experience and improved system reliability.
