Presentation

I provide end-to-end web application development services, taking your idea from concept to a fully functional, deployed web application. Whether you need a new website, a business application, or a custom web solution, I can help at every stage of development.

My End-to-End Services Include:

Planning & Requirements: Understanding your idea, defining features, and planning the application structure.
UI/UX & Frontend Development: Creating responsive, user-friendly interfaces using React.js, JavaScript, HTML, and CSS.
Backend Development: Building secure and scalable backend systems using Java, Spring Boot, REST APIs, and Node.js.
Database Development: Designing database schemas, relationships, queries, and data management using MySQL or PostgreSQL.
Authentication & Security: Implementing login, registration, role-based access, and secure API integration.
API Development & Integration: Connecting frontend and backend services and integrating third-party or AI APIs.
Testing & Bug Fixing: Testing features, fixing errors, debugging issues, and improving performance.
Deployment & Launch: Configuring the production application, deploying the frontend and backend, connecting the database, and setting up environment variables and domain configuration where required.
Post-Deployment Support: Helping troubleshoot issues and maintain or improve the application after launch.

My goal is to deliver a complete, reliable, responsive, and fully functional web application—not just a design or a collection of code files.

From the initial idea and development to testing, deployment, and launch, I can help turn your requirements into a working product. I value clean code, clear communication, and practical solutions tailored to your needs.

Background

Full Stack Developer
Educational Testing Services · 03/07/2025 – 18/07/2026
I have around 1 year of professional full-stack development experience at Educational Testing Service (ETS), where I worked on production web applications, including the TOEIC Link assessment platform.

My experience includes developing frontend interfaces using React.js, JavaScript, HTML, and CSS, along with backend development, REST API integration, and troubleshooting using Java, Spring Boot, and SQL. I also worked on improving web accessibility following WCAG 2.2 Level A guidelines, resolving production bugs, and supporting reliable application performance across browsers.

Alongside my professional experience, I have worked on projects involving AI integration, Gemini APIs, Python, FastAPI, and database management.

As a freelancer, I can help clients build complete web applications from planning and development to testing, deployment, and post-launch improvements. I focus on clean code, responsive design, reliable functionality, and clear communication throughout the project.
