I am a third-year student on track to graduate in 2027 with a First-Class Honours BSc (Hons) in Computing. My interest lies in the engineering challenges of building and maintaining large-scale consumer applications and the internal tools that support them. I am actively seeking an internship with a team that operates at this level to gain practical, real-world experience and contribute to impactful projects.

Projects

FileShare

A secure, anonymous file-sharing web application.

Key Engineering Decisions:

  • Cost-Effective Storage: Chose Cloudflare R2 for its S3-compatible API and zero-cost data egress. This was the key financial decision making a public file download service sustainable, as standard S3 egress fees would be really expensive.
  • Production-Grade Security: Implemented Caddy as a reverse proxy on AWS EC2 to automatically provision a Let's Encrypt SSL certificate. This cleanly solves the browser's mixed-content security policy (https frontend talking to http backend) and offloads all TLS complexity from the application code.
  • Guaranteed File Deletion: Leveraged PostgreSQL’s native `TIMESTAMPTZ` data type for the `expires_at` column, enabling a time zone-agnostic `@Scheduled` cleanup job in Spring Boot that enforces the 24-hour data deletion guarantee with absolute reliability.

Movies PWA

A responsive and performant movie discovery Progressive Web App.

Note: This project was built two years ago to demonstrate frontend fundamentals and has been running continuously as deployed.

Key Frontend Decisions:

  • Optimized Performance: Built with Next.js for its server-side rendering (SSR) capabilities, ensuring fast initial page loads and excellent SEO performance, as verified by Lighthouse scores.
  • Robust Testing Strategy: Implemented a comprehensive testing suite, including unit tests with Vitest and React Testing Library for individual components, and end-to-end (E2E) tests with Cypress to validate critical user flows like searching and navigating to a movie detail page.
  • Maintainable Styling: Utilized SCSS Modules to scope all CSS classes to their respective components. This prevents global stylesheet conflicts and makes the UI components truly modular and reusable.

BankApp (Academic)

A desktop WPF application demonstrating core Object-Oriented Programming principles.

Key OOP & Design Decisions:

  • 3-Tier Architecture: Strictly separated the application into three distinct layers (DAL, BIZ, UI) to enforce separation of concerns. This ensures that business logic is completely independent of the database and the user interface.
  • Secure Authentication: Implemented secure password handling using the `Rfc2898DeriveBytes` (PBDFK2) algorithm. A unique salt is generated for each user, hashed with their password, and stored.
  • Role-Based Access Control (RBAC): All permission checks (e.g., transaction approvals requiring a "Manager") are enforced in the Business Logic Layer (BIZ), not the UI. This server-side validation is a critical security practice that prevents unauthorized actions.
