Iโm a Senior Mobile App Developer ๐ with over 4+ years of experience ๐
I help startups and businesses craft intuitive and stunning mobile apps without compromising quality. Flutter Developer | Cross Platform Engineer | Android & iOS Service ๐ผโ๏ธ
With my over 4 years of professional experience in Mobile Applications Development, Iโve had the incredible opportunity to work with different teams from different companies on a number of diverse projects that have further sharpened my prowess in the realm of Mobile Applications Development.
Having been the brain behind many user-engaging apps, enterprise solutions, birthing an ordinary conceptualized idea to life from merely an idea to deployment is a great achievement that makes me stand out and would forever be proud of.
Beyond just writing the code that โworksโ, Iโve always been committed to excellence, leveraging cutting-edge technologies, both those majorly within my stack, and also from third parties in form of libraries or SDKs.
Adding flavour to my competency is my crave for wanting my apps not just to meet expectations, but also exceed it by integrating some other cool and interesting features that makes my team wowed. One of this is usually in form of me enabling theming and adding cool, smooth transition animations.
As I look forward to a potential role here, I look forward to further letting my creativity serve, soothe and quenches the thirst of wider audience, which is what Iโm always proud of.
With my proven track record of delivering results and a steadfast dedication to excellence, I am confident in my ability to drive impactful change and propel a prospective company/team Iโd be working with towards new heights of success.
