Full-Stack Web and API Development (Node.js, React, SQL)

I'm Mark, a BSIT graduate with hands-on experience building backend systems, not just following tutorials. I can help you build, fix, or improve your web application, from the database up to the user interface.

Services

Backend and API Development
- REST APIs using Node.js and Express
- Authentication systems with JWT, including login, sessions, and token refresh
- Role Based Access Control (RBAC) to manage different user permissions, such as admin versus regular user
- Database design and queries with SQL
- Fixing broken or slow backend logic

Frontend Development
- Building user interfaces with React
- Connecting frontend to backend APIs so the application works end to end
- Basic to intermediate responsive design


Full-Stack Projects
- Taking a project from concept to a working application
- CRUD applications, dashboards, admin panels, and small business tools
- Debugging existing codebases on the Node, Express, and React stack

Why work with me
I am new to freelancing but not new to building software. I have completed a hackathon project with IBM and built full REST APIs with proper authentication and role management. I am currently in interview processes with several companies in the Philippines, so I am used to explaining my code and decisions clearly rather than just delivering it without context.

I communicate directly, do not overpromise, and will tell you upfront if a request falls outside my current skill level rather than waste your time and budget.

Good fit for
- Small businesses or startups needing a simple web application or internal tool
- Developers who need additional support on a Node or React project
- Clients who need an API built or fixed, with proper login and access control
- Bug fixes or feature additions on an existing Node.js, Express, or React codebase

Not currently offering
- Complex DevOps or infrastructure work
- Native mobile app development
- Large enterprise scale systems

Tools used: Node.js, Express, React, SQL (MySQL/PostgreSQL), JWT, Git
