Fullstack Web Developer & Linux Server Expert
Profile
Brief Overview of Background and Experience
As a web developer, I possess extensive experience in developing custom e-commerce stores, websites, and in implementing management, CRM, and ERP systems. I am proficient in PHP and the CodeIgniter framework, with strong skills in JavaScript and CSS technologies. Additionally, I have worked on several React and React Native projects. My personal passion lies in server-side management, particularly in mastering and continuously learning about Linux-based systems (Debian/Ubuntu).
In my work, I place great emphasis on the secure construction of applications. I have also gained significant experience in the field of SEO. I consider client communication and relationship management to be my strengths.
My hobbies also include other areas of development, such as embedded system development based on Python (esp32). Another strength I would like to mention is my experience with large corporations (National Instrument). Here, I developed and implemented a proprietary equipment management and maintenance system for the company's site in Penang, Malaysia.
I enjoy nature and hiking, and traveling.
