Building e-commerce solutions at BigCommerce
Toronto, ON, Canada
I'm passionate about creating software that solves real problems and makes a difference. With over 5 years of experience in full-stack development, I love building scalable applications that can handle millions of users while staying maintainable and elegant. Whether it's architecting microservices with Spring Boot, crafting responsive frontends with React, or orchestrating deployments with Kubernetes, I enjoy every aspect of the development lifecycle. I've had the privilege of working on everything from healthcare platforms serving half a million patients to e-commerce systems processing thousands of transactions daily. Currently, I'm focused on building next-generation e-commerce solutions that help merchants grow their businesses.

Featured Projects
Real Estate Management Platform
I developed a comprehensive real estate management system with Next.js, TypeScript, and Material UI, backed by Spring Boot microservices. The platform features property listings with advanced search, role-based access control, favorites system, and analytics dashboards. I implemented a microservices architecture for users, properties, analytics, and contact management, ensuring scalability and maintainability. The application includes multi-language support and responsive design across all devices. My focus on security best practices and API integration resulted in a robust solution that streamlines property management for agents, administrators, and clients.
Microservices E-Commerce Platform
I built a high-performance e-commerce platform using a microservices architecture. This platform leverages Express.js (Node.js), MongoDB, and React.js for a seamless user experience. To ensure continuous delivery and minimize downtime, I implemented CI/CD pipelines with Azure DevOps, resulting in a 70% reduction in deployment time. Furthermore, I utilized Terraform for efficient cloud resource management and integrated ELK/Prometheus for robust monitoring and logging, achieving 99.9% uptime.
Toronto GTA Investment Map
I developed a responsive real estate investment analysis platform focused on the Greater Toronto Area. This application helps property investors identify and evaluate investment opportunities across different locations using interactive maps with heat mapping visualization. Key features include location-based investment scoring, financial analysis tools for calculating ROI and cash flow projections, portfolio tracking, and comprehensive property details with mortgage calculators. The app includes an analytics dashboard that visualizes investment trends and performance metrics, and generates exportable reports. The application uses React with Leaflet for mapping, Recharts for data visualization, and local storage for data persistence.
Job Application Tracker
I developed a comprehensive job application management system using React, Tailwind CSS, and modern web technologies. This application helps job seekers track their applications across multiple companies, monitor application statuses, and analyze their job search through an interactive dashboard. Features include company management, application status tracking, follow-up reminders, interview notes, and analytics visualizations. I implemented robust error handling, local storage for data persistence, and CSV import/export functionality for data backup.
