Hi! I'm a Software Engineer experienced in building scalable, high-performance applications and working with cloud technologies. I specialize in full-stack development, data optimization, and system enhancements. Currently, I am contributing to Sakai LMS Development and mentoring students as a Computer Science Tutor at Marist College.

• Sakai LMS Development & Enhancement:
  • Developed and scaled a live-stream pipeline from 200 to 300,000 users per session.
  • Expanded streaming channels from 2 to 250+.
  • Focused on accessibility improvements, bug fixes, and backend solutions for on-demand content using AWS.
  • Ensured WCAG-compliant features to improve LMS usability and reliability.
  • Worked closely with staff to gather feedback and implement continuous improvements.

• Provide personalized tutoring sessions in Computer Science, covering topics like:
  • Programming languages (Java, Python, JavaScript)
  • Data Structures & Algorithms
  • React, Redux, JavaScript, and more.

• BNYMellon Project:

• Designed, developed, and maintained efficient and scalable Single Page Applications (SPAs) and Multiple Page Applications (MPAs) using React and Angular, ensuring high performance and responsiveness across devices.

• Built reusable component libraries for Disclosures and Notifications, reducing development time by 30% and ensuring consistency across applications.

• Integrated RESTful APIs into React applications to streamline data flow and enhance user interface performance, reducing latency by 25%.

• Identified and implemented web-based user interactions, creating highly responsive and intuitive UI components using React workflows and state management libraries like Redux (Thunk/Saga).

• Developed graph-based infographics and customisable data view navigations using micro-frontend architecture, enabling modular and scalable application design.

• Collaborated with cross-functional teams, including Product Managers, UX Designers, and Backend Engineers, to translate verbal client requirements into written use cases and testable development stories.

• Improved test coverage by 40% through Functional Testing and Integration Testing using tools like Jest and React Testing Library (RTL).

• Documented technical workflows, best practices, and knowledge in a private wiki, facilitating the onboarding of new hires and ensuring knowledge retention for future use.

• Set up and managed AWS infrastructure for build and deployment pipelines, including S3 for static asset hosting, EC2 for application servers, and Lambda for serverless functions, ensuring seamless CI/CD workflows.

• Configured AWS CloudFront for content delivery, reducing load times by 20% and improving user experience.

• Implemented AWS CodeBuild and CodePipeline to automate build, test, and deployment processes, reducing manual errors and deployment time by 50%.

• Monitored application performance using AWS CloudWatch, identifying and resolving bottlenecks to ensure optimal system performance.

• Worked in Agile methodologies (Scrum), participating in daily stand-ups, sprint planning, and retrospectives to deliver high-quality features on time.

• Mentored 10+ junior developers in React, Redux, and micro-frontend architecture, improving team productivity and code quality.

• Conducted code reviews to ensure adherence to best practices, maintainability, and scalability of the codebase.

• Championed accessibility best practices, ensuring compliance with WCAG standards and improving usability for diverse user groups.

• Optimized web applications for SEO and performance, achieving Google Lighthouse scores above 90 for performance, accessibility, and best practices.

Key Achievements:

• Delivered 5+ scalable SPAs and MPAs for enterprise clients, reducing development time by 30% through reusable component libraries.

• Improved application performance by 25% through REST API optimisations and AWS infrastructure setup.

• Automated CI/CD pipelines using AWS CodeBuild and CodePipeline, reducing deployment time by 50%.

• Achieved WCAG compliance for all front-end applications, improving accessibility and user satisfaction.

• Developed solutions for pose recognition using ergocentric videos and DynamoDB for managing millions of daily API calls.
• Automated Git pull request merges, improving code integrity and reducing manual intervention.
• Created productivity-boosting scripts to streamline development workflows.

Here are a few highlights of the projects I've worked on:

• Sakai LMS Enhancements: Contributed to Sakai LMS by improving accessibility, scalability, and backend functionality.
• Real-time Data Processing with Apache Spark: Built high-speed data processing solutions handling up to 1M records/sec.
• React & Redux SPA Libraries: Developed reusable libraries and optimized frontend performance.
