In 2026, I performed a complete overhaul to meet the client's high-end brand positioning needs. The technical architecture was streamlined by unifying two Next.js instances, effectively reducing technical debt and optimizing load times.,

Visually, I designed a sleek, premium interface that showcases the photography portfolio. Developed with a Mobile-First approach, the application ensures a seamless and intuitive experience across all devices while maximizing visitor conversion rates.

An interactive tool that helps users make decisions through head-to-head comparisons. Users input a list of items, and the app presents them in pairs (or triplets) for selection. Winners move to the next round until a final champion is crowned. Useful for rankings or making fun, interactive choices.

A showcase website for a fictional dental center built with Vue 3, TypeScript, and TailwindCSS. This project focused on creating a modern, responsive interface with a high execution speed and clean design.

A robust CLI tool built with TypeScript to automate README creation. It intelligently extracts metadata from package.json and uses interactive prompts to gather project details. I focused heavily on code quality, achieving over 90% code coverage with Jest. The tool is published on NPM for easy global installation.

My first project using the Angular framework. This dynamic frontend application allows users to explore movies and TV shows by fetching comprehensive data from The Movie Database (TMDB) API. Key learning milestones included:

1. Creating reusable components and services.
2. Managing routing and application state.
3. Handling asynchronous data with HttpClient and RxJS Observables.
4. Implementing a responsive UI with search, pagination, and loading indicators.

This project is a custom iteration of my Next-Portfolio, specifically tailored for a professional photographer. It leverages a robust dual-app Next.js architecture (Admin & Showcase) with MongoDB Atlas, while integrating key features for this specific use case:

1. Automated Email Notifications: Instant alerts via Nodemailer for new contact form submissions.
2. Domain-Specific Customization: Refined design and content organization optimized for high-quality visual portfolios and galleries.
3. Core Feature Inheritance: Benefits from full dynamic CMS (albums, projects), secure authentication (NextAuth.js, Argon2), Cloudinary image optimization, and protected forms (reCAPTCHA v3, rate limiting).

In 2026, I performed a complete visual overhaul and technical restructuring, migrating from two separate apps to a single centralized architecture to improve deployment efficiency and performance.

When integrating Jest tests into a Next.js project with a decoupled frontend/backend architecture, standard GitHub Actions lacked the granularity to distinguish between different test results. To improve Pull Request reporting, I modified the willcaul/jest-github-action. This enhancement allows specifying and executing multiple Jest configurations within a single workflow, providing clear, separate reports for server and client components.

A modular full-stack CMS and digital showcase. The admin dashboard provides a robust interface for managing blog posts, photo albums, and projects with granular role-based access control (Admin, SuperAdmin, UltraAdmin). The showcase application focuses on performance, SEO, and security, implementing reCAPTCHA v3 and IP-based rate limiting.

A CodePen-inspired platform featuring a Node.js backend and a Next.js frontend. This ambitious project utilizes GraphQL and Apollo for communication, TypeORM with PostgreSQL for data management, and a comprehensive testing suite (Jest & Cypress).

An Uber Eats-inspired meal delivery application. Built with Vue.js for a dynamic UI, TypeScript for type safety, Docker for containerization, and Tailwind CSS for modern styling.

An Airbnb-style rental platform developed with Symfony, PHP, and MySQL, featuring booking and listing management.

A Quora clone powered by Symfony, managing complex relations between users, questions, answers, and votes.

A functional replica of Twitter/X built with Node.js. It features Pug templating, Express routing, and MongoDB. This project served as a deep dive into the architecture of complex social media platforms.

An innovative AI-powered chat application integrating ChatGPT. This ambitious project focuses on creating an intelligent, interactive conversational experience by leveraging OpenAI's capabilities. Built with a Node.js backend and a React frontend, it utilizes React Redux for robust state management. Using Vite ensured a high-performance development workflow, while the API integration offered a rewarding technical challenge in handling real-time AI responses.

A high-performance single-page application for fitness coaching, built with TypeScript, React, Vite, and a Node.js backend.

My initiation into React, focusing on fundamental concepts like components, state management, and conditional rendering.

A web implementation of the classic board game using Webpack to optimize resources and Sass for styling.

A JavaScript-based logic game focused on state management and DOM manipulation.

A dynamic application integrating a REST API for data persistence, focusing on CRUD operations and styled with Sass.

My first step into web development, focusing on the fundamentals of the DOM, HTML structure, and CSS layout.
