JAVASCRIPT – SENIOR SOFTWARE ENGINEER

SUMMARY
Hi, I am Joshua Oguma, a software engineer with a B.Sc degree in Software
Engineering in Kharkiv National University of Radio Electronics and about 5 years of
experience in commercial Web development.
I am well versed in using HTML, CSS and JavaScript, Angular, RxJS and NgRX for
solving problems at the UI level as well as in documenting UI components using
Storybook. I am also adequately skilled in using a variety of WebAPIs for building
great user experiences and also fairly equipped on the server-side using NodeJS and
MongoDB as well as integrating with Third party server-side APIs.

So I have a desire to transition into full stack but my strong points are on the Angular
Ecosystem (Angular/Ngrx/RxJs). And I also have experience mentoring 7 people
coming from a Hybris (Java) background into using Angular, RxJS and NgRx
technologies during my time in Epam Systems and I currently mentor upcoming
software engineers during my free time.

I have worked on several client projects as an outstaff fulltime employee of Epam
Systems and as a freelancer to EduFront as well as in other companies like (Glorium
Tech, Rews Consulting and Ciklum. But I’m currently working in REWs consulting as a
senior Angular Developer.
