About
I’m a hard-working, fast learner who is a proven Software Engineer with a 4-year Computer Engineer degree and 3+ years of work experience. As a dedicated problem solver who is skilled in programming languages including libraries/frameworks, I’m eager to solve real-world problems through the use of my skill and technology. Through my time at Dialog Axiata PLC, I have gained further hands-on experience in industry-standard development, which I’m looking to apply at an ever-growing organization. I’m also a great team player, although I’m also able to overcome obstacles independently.
