About

Turning ideas into practical, production-ready software.

My work is centered around backend-heavy web development with Java. I like projects where authentication, database design, and business logic matter just as much as the interface.

Through hands-on projects, I've worked with Servlets, JSP, JDBC, Oracle SQL, HTML, CSS, and JavaScript to build complete applications that support real user flows instead of isolated demos.

I’m focused on improving system design, shipping dependable features, and contributing to teams that value clean execution and ownership.

Backend-first mindset

I care about session handling, data flow, validation, and maintainable logic.

End-to-end ownership

I enjoy taking a feature from UI planning to database integration and testing.

Product focus

I actively build, iterate, and improve based on what each project needs to do for real users.

Projects

Work that shows both backend depth and product thinking.

Preview of the Online Examination Portal project

Featured project

Online Examination Portal

Java • Servlets • JSP • JDBC • Oracle SQL • HTML • CSS • JavaScript

A full-stack online examination system with separate admin and user experiences, automatic evaluation, timed assessments, and result tracking backed by Oracle SQL.

My role Designed backend flows and database-driven exam logic
Why it stands out Handles timed submission, access control, and result history

What it solves

Digitizes exam management so admins can create and control assessments while users can take secure timed tests and instantly review results.

What I built

Authentication flows, session-based access control, timed exam submission, question retrieval through JDBC, result generation, and history views.

  • Implemented role-based access for admin and user modules
  • Built secure login, registration, password updates, and session management
  • Connected dynamic question loading and result processing with Oracle SQL
  • Created timed exam behavior with automatic submission on timeout
  • Designed dashboards for exam management and score history tracking
