Hi there,
I am Wael Hasan, an Egyptian Senior Full-Stack JS/TS web developer, with 10 years of total web development experience, 8 of them using MERN stack.
I build a high quality Functional and Object Oriented code, plus being a testing enthusiast, which makes me thrive to have a 100% test coverage for all of my codes, whether they are frontend projects, or backend projects.
I am searching for an opportunity for a
Backend Nodejs developer
- Passion for being a better software engineer
- Passion for learning more about technology in general and JS in particular
- Fast learner
- Passion for building well engineered useful stuff and see people use it happily
- Good team player
- A lazy developer that searches for the simplest best way to make the code as reliable, self-documenting, and maintainable as possible; so it takes less effort for any change from me or my colleagues
- To do repetitive work, that does not leverage my technical skills
- If you work on an industry that contradicts with my faith and believs, or I prefer to stay away from, which are: banking, insurance, racism, porn, weaponary.
