What I'm looking for

I’m looking for remote, hybrid, or on-site web development opportunities where I can work across application development, integrations, deployment, maintenance, and production support.

At WEBMOVILSYSTEM, I built and maintained responsive web applications using PHP, JavaScript, and MySQL. I developed frontend interfaces and backend functionality for web-based applications.

I integrated REST APIs and third-party services, connecting application data with APIs, JSON, and relational databases. I also developed features and enhanced existing applications to meet project and business requirements.

I managed deployment and publishing to production environments, and supported web hosting, domains, DNS, web servers, and FTP. I tested applications and provided ongoing production support and maintenance.

At IXOSYSTEM and GOAPPIFY, I developed and maintained web applications and websites, supporting integrations, deployment, and troubleshooting. I also created and edited web graphics and digital assets using Adobe Photoshop at WEBMOVILSYSTEM.
