Portfolio
I joined the team as a front-end developer to build the decentralized application based on RSK network, one of the solutions built on Bitcoin.
As a mid-senior developer in the team with 15 members, I committed my work and reviewed the pull requests from other developers as well.
I was assigned to add new features to website and to build a new DeFi application.
I’ve developed the launchpads for new Tokens, Mynt and Zero, which finally raised $ 2M.
With application, I developed the features like staking, launchpad, claim and landing pages.
The company raised $ 2M in 2 presales, in which the launchpads I built were used.
As an only developer, I built the user interface of this admin panel.
The goal is to build the pages in pixel-perfect as given in Figma design.
I designed the structure of the application and built the authentication pages, dashboard with charts, and data tables to list data.
I delivered the application in time after revising the issues several times.
I worked as a front-end developer with 5 developers in this project.
The goal was to build a desktop application that can monitor the twitters with the various options.
My role was to build the monitoring module in the customer version.
I developed the interface in pixel-perfect and integrated the Twitter API v1.
The company increased the followers by 30%.
The difficulty was to avoid the rate limiting using proxy and to leverage the efficient twitter API for better performance while getting all the necessary information.
As an only developer, I built this panel from scratch. There were 2 mobile developers, and I was a full-stack developer to build API and admin panel.
First goal was to build the interface that can manage the app data as the restful API gets ready.
I developed the application by myself from scratch while communicating with the client and mobile developers.
We upgraded the API from using Firestore and firebase function to using Node.js and MySQL.
With the changes of API, I integrated new API features into the panel like ID verification, reports, language update and etc. Finally the mobile applications have been published on Google and Apple stores.
I worked directly with the client as an individual developer.
The goal was to increase the loading speed by revamping styling system.
The old version used multiple CSS libraries but the client wanted to use only one library Tailwind CSS and to purge the unused CSS classes.
Finally the website has been formatted using Tailwind CSS, and css bundle reduced by 80%, improved the loading speed 50% above.
