Isiah Christian S.

Application Systems Developer

I am a Software Engineer with nearly more than 5 years of professional experience, primarily working with Java EE, JSP, PostgreSQL, MySQL, and Oracle 19c. Throughout my career, I have developed and maintained enterprise applications while gaining experience in database design, backend development, and system support. In addition to my core expertise, I have working knowledge of HTML, CSS, Bootstrap, basic JavaScript, ReactJS, WordPress (Divi), and Adobe Photoshop, allowing me to contribute to both technical and user-facing aspects of web development. I am currently focused on expanding my skills in Python, with the goal of developing automation solutions for repetitive tasks, advancing into data science, and building expertise in cybersecurity. Beyond software development, I am also a duly licensed Electronics Engineer (ECE) and Electronics Technician (ECT), having successfully passed the board examinations. My combination of software engineering experience, database expertise, web development knowledge, and engineering credentials enables me to approach complex technical challenges from both software and electronics perspectives while continuously pursuing opportunities for growth and innovation.
