I have a masters degree in computer applications and have been working as a full stack mobile and web developer for many years now. I've learned a lot from my experiences and am always eager to learn more and explore. I have taken numerous applications from ideas or figma designs to production applications on AWS, Google Cloud, Firebase, Google Play Store or Apple App Store with CI/CD setup with pipelines triggered from GitHub actions. I love what I do and it feels so good to say that "Yes It can be made better". There are always a thousand ways to implement a feature but the pursuit for most efficient and reliable way is the goal. Like Martin Fowler said "Any fool can write code that a computer can understand. Good programmers write code that humans can understand.”, I always like to write code that is easy to read, manage and scale.

Most software projects don’t fail because of missing features.

I build and maintain web applications using React, Node.js, databases and cloud deployment. I focus on writing clean, scalable, and maintainable code that can grow with the product.
