5+ years of experience using JavaScript frameworks/libraries/tools. I have Bsc. in Computer Science with strong background in programming, and considerable experience using cutting-edge software development tools.
I'm a passionate and result-driven software engineer with over 7 years of hands-on experience using JavaScript and its related stacks: NodeJS, ReactJS, Angular 14+, NestJS, Typescript, jQuery, Babel, Webpack, etc. I have Bsc. in Computer Science with strong background in programming, and considerable experience using contemporary software development tools.
I'm extremely skilful using Relational Databases such as MySQL and PostgreSQL, and No SQL database like MongoDB. Occassionally, I also work with Laravel (PHP Framework).
I'm productive in both team-based and self-managed projects, and passionate about working with state-of-the-art technologies. I like to get things done but only in the right way: taking into account the scalability, maintainability, performance, efficiency, effectiveness, robustness, security, and most importantly, the business needs and values of any platform/application I find myself working on.

I have always been a big fan of JavaScript starting from those days I used it mainly for DOM manipulations, back in 2012. I have quite a lot of experience in JavaScript. I have followed JavaScript all along seeing it evolve from just DOM manipulations to the server (using NodeJS), to Desktop (using Electron) and presently for Mobile applications (using Cordova, React Native, etc.).
I have worked a lot with old and state-of-the-art javascript framworks/libraries/tools, ranging from NodeJS, jQuery, AngularJS, Angular, React, Meteor, React Native, Babel etc. Also as an advocate of TDD, I, all the time, do bunch of testings leveraging JavaScript testing tools like Mocha, Supertest, Nightwatch, Selenium, Jasmine, Chai, Protractor, Enzyme, Jest, and Karma.

I started using React in the early 2016, few months after I graduated from University. Since then, I have been a big fan of React.
Over the years, I have built plethora of Single-page applications using React for clients and for personal use. I have thought React and also contributed to React-related projects. React is my most revered JavaScript library; I have seen it grow and being embraced significantly by the JavaScript community since its advent in 2015.
Working with React is undoubtedly the best thing that have happened to me in programming with JavaScript. I will be more than glad sharing my knowledge and expertise with anyone interested or in need of my services.

I'm an Expert with hands-on experience in Node.Js. I have worked with several teams and firms buiding applications that have to do with Node.JS and other server side tools, like EJS, PassportJS, ExpressJS, etc. If there is one area I can boast to be good at in JavaScript ecosystem, it's definitely NodeJS.

I'm a big fan of OOP, having began my programming with Java before shifting focus back in 2012. The experience I do have using TypeScript with React and Angular is unparalleled. I'm very experienced in it and will be happy working with anyone using it.

I began my web development journey back then in 2012, and HTML/CSS was my first point of action. Over the years, I have acquired a lot of experience using HTML/CSS; I have built several mockups, prototypes, and web pages that have to do with HTML/CSS or its emerging frameworks/libraries such as Bootstrap, SASS, SCSS and LESS. As a web developer, HTML/CSS is part of my daily routines, and I love writing it — as it happens to be the cornerstone of web applications.

Jimoh is a javascript wizard! Plus he really stuck with my problem. We finished when the code was bug free and working like a champ. Will definitely work with Jimoh again!

I'm working on a long, complex project. I am a data engineer in my day job so I know a good deal about what I want to do, but I am not an expert in react and mongo db. Jimoh takes the effort to understand the complexities of this project
