Projects

Mersys Campus – Full-Stack Development of a Large-Scale EdTech SaaS Platform

I worked as a Senior Software Engineer and team lead on Mersys Campus, a large-scale EdTech SaaS platform used by schools, universities, and training centers. The platform includes Student Information System (SIS), Learning Management System (LMS), ERP modules, reporting, assessments, HR, finance, and scheduling — all delivered as a multi-tenant SaaS solution. My role covered the full stack with a strong focus on designing scalable backend architecture and delivering polished, performant front-end interfaces used daily by thousands of users. Key contributions: • Led development of core modules in SIS, LMS, and ERP using Java, Spring Boot, Angular, MongoDB, and microservices. • Refined and improved complex UI workflows across the platform, ensuring consistency, usability, and clarity for non-technical users. • Optimized critical reporting features, reducing load time significantly and improving the overall user experience. • Introduced better component structures in Angular to support maintainability and consistent UI behavior across different modules. • Worked closely with designers and product teams to transform rough requirements into smooth, intuitive UX flows. • Mentored junior developers, ensuring high coding standards and aligning the team with best practices. • Implemented system improvements that resulted in better performance, simplified navigation, and more efficient daily operations for client institutions. Mersys Campus remains one of the most comprehensive EdTech SaaS platforms in the region, and I contributed end-to-end to its architecture, user experience, and overall stability. See More

I contributed as an Expert Software Engineer to ObvioGo, a digital clinical trials platform focused on improving participant engagement and streamlining study operations. My work supported multiple teams and helped enhance both system performance and the user-facing components of the platform. My contributions included: • Building and refining core front-end features using React Microfrontends to ensure a modular, scalable architecture. • Improving UI consistency across participant and study coordinator interfaces, enhancing clarity and ease of use. • Developing backend services using NestJS and MongoDB, enabling faster data workflows and more reliable study operations. • Implementing event-based microservices with Kafka to support real-time interactions and improve system responsiveness. • Establishing front-end best practices that accelerated team productivity and reduced onboarding time. • Collaborating closely with designers, product owners, and clinical operations teams to translate study requirements into intuitive user experiences. • Leading code reviews, driving quality improvements, and mentoring engineers across multiple teams. Impact: • Reduced clinical study setup time significantly—from approximately 3 months to 1 month—by optimizing architecture and front-end workflows. • Improved performance and developer experience across the platform, contributing to faster delivery cycles and smoother user journeys. ObvioGo remains a key platform in decentralized clinical trials, and my contributions strengthened both its technical foundation and overall user experience. See More
