PROFESSIONAL SUMMARY
Information Systems student (graduating 2026) with hands-on experience building a full-stack web application end-to-end:
React/TypeScript frontend, Node.js/Express backend, and PostgreSQL database. Comfortable across HTML, CSS, JavaScript, and React
on the frontend, with relational database design, SQL, and server-side logic on the backend. Additional exposure to Windows Server
administration and Docker. Seeking an Intern/Trainee Frontend Developer role to apply these skills on a real product team.

TECHNICAL SKILLS
Frontend: HTML, CSS, JavaScript (basic), React, TypeScript, Tailwind CSS, Vite, Axios
Backend & APIs: Node.js, Express.js, REST API design, JWT authentication
Databases: PostgreSQL, MySQL, Prisma ORM, relational schema design, SQL
Version Control & DevOps: Git, Docker
Systems: Windows Server, Active Directory, VirtualBox

FEATURED PROJECT
TechZone — Full-Stack E-Commerce Web Application — Personal project
Designed and built a complete online electronics store covering the frontend, backend API, database schema, and core e-commerce
business logic. Used an AI coding assistant (Claude) to accelerate implementation, while personally designing the architecture, data
model, and security logic.
• Built the storefront in React 18 + TypeScript with routing (React Router), Tailwind CSS styling, and Axios-based API integration;
implemented product catalog with search, category filters, sorting, and pagination.
• Implemented authentication and role-based access (user/admin) with JWT and bcrypt password hashing, including a protected
admin dashboard for product and order management.
• Designed the PostgreSQL schema with Prisma ORM (migrations + seed data) and built a REST API in Node.js/Express covering
auth, products, cart, and orders.
• Implemented server-side order logic where prices and stock are validated and computed from the database inside a transaction,
so client-submitted prices are never trusted — preventing price-tampering.
• Added request validation (Zod) on both client and server, rate limiting on auth endpoints, Helmet security headers, and CORS
allow-listing.
• Wrote unit and integration tests (Vitest, Supertest, React Testing Library) covering JWT logic, validators, and protected routes.
Stack: React, TypeScript, Vite, Tailwind CSS, Node.js, Express, PostgreSQL, Prisma, JWT, Zod, Vitest.

ADDITIONAL PRACTICAL EXPERIENCE
• Developed static websites using HTML and CSS, applying structured, semantic layouts and responsive styling.
• Designed and implemented relational database schemas; wrote complex SQL queries and managed indexes and table
relationships.
• Configured and administered Windows Server in a virtualized environment (VirtualBox), including Active Directory setup.
• Used Docker to containerize applications and standardize development environments.
