Begize Specimen Referral System

A mobile application for KNCV, a tuberculosis organization that was built with Flutter. The project aids in streamlining the exchange of specimens between referring medical facilities, carriers, and testing medical facilities.

Using couriers or transporters who accept orders from referring healthcare facilities to the chosen test center, referring healthcare facilities can send orders, including patient specimens, to neighboring test centers. Once orders from referring medical facilities have been received via couriers or transporters, the test centers submit the results via the application.

Along with additional user management tools, it also provides front-end web panels allowing users to interact with the application and achieve features comparable to those listed in the mobile application.

It is tailored for isolated areas where the internet might not be accessible. Despite the lack of internet access, orders can still be placed via SMS.

We mainly used BLoC, DIO, GetIt, Firebase, Hive, and other tools to build this application.

FETS Project Management Tool

A web-based project management tool that allows donors to check and balance expenditures. There are two kinds of users on the system – project managers and budget managers. The application enables these users to control costs spent on a project.

Projects are divided further into sub-projects and tasks for further audit and compliance. It gives more security as the flow goes hierarchically from budget managers to project managers.

There is also added transparency between donors and project managers as they get timely reports once tasks are done. We built individual Flutter-based sections for donors to check these reports.

The main tools we used to build the application are React with Material UI, PostgreSQL, Web3.js, and Express.js.

CNCM Copyright Management Tool

A React and Flutter-based copyright management tool to manage user assets and get the asset owners paid whenever their assets are used by TV or radio stations.

It also aids associations in managing their assets and generating income from their platform-saved assets. The tool features a mobile application that allows asset owners to view their revenue and make subscription payments.

Movie Streaming Application

A React Native-based application that allows members to stream movies and trailers. Users of the application can purchase a variety of bundles and view TV series and films of their choice. Back-end and mobile front-end development were part of my responsibilities on this project.

We used React Native for the front end and Express.js for the back end. It is a component of the Meda Garage platform, an application marketplace similar to the Play Store.

Taxi Dispatcher Payment Application

A Flutter-based payment application for a local Uber-like taxi dispatcher application in which users can pay for what they use and buy or send packages to their friends or relatives. It has more than four bank payment integrations to make transactions easier for all customers. Corporations can also pay their employees for taxi usage using the application.

We used BLoC for state management, Dio for API requests, GetIt for dependency injection, and shared preference to save users' insensitive data.

The application has more than 50,000 downloads on the Google Play Store, and it has played a big role in significantly facilitating the taxi dispatching process.

Queens Inventory

An Electron-based application to manage inventory for one of the biggest supermarkets in Ethiopia, Queens supermarket. It has many custom report tools shipped with it to determine which items are low and which are high in stock. We used Electron for IPC calls and React to render the UI.

I participated in the development process from the front to the back end. The main tools we used to build the application are React, Electron, Express.js with MongoDB, and TypeScript.

Music Streaming App

https://play.google.com/store/apps/details?id=com.sewasewmusic.music&hl=en&gl=US
A Flutter-based music streaming application that allows users to listen to music and podcasts. They can also download music of their choice to their device locally, so they can listen to it when their internet access is limited or non-existent.

I was a front-end developer working with Flutter following the requirement specification, implementation, and testing phases.

Job Application Tracking System (ATS)

A React-based application to link employers and job seekers. Employers and employees can register in our system, simplifying the application tracking procedure. The application helps employees or job seekers see daily job postings and apply for specific jobs. It also helps employers reduce the stress of finding suitable applicants.

OpenInfuse

A Flutter-based mobile and React-based web application that nurses can use to manage patients' appointments, inventory, and everything related to the IV infusion process. The web app is mainly used to send patients consent screens and compliances.

Tenancy Management App

A Flutter-based mobile application that helps landlords and tenants manage their arrears, documents that need renewal, and documentation needed to undergo the tenancy and landlord mapping, including single properties and HMOs.
It uses Crezco, which is a new payment provider in the UK.

Pitchle

An application built with Flutter that brings together investors, entrepreneurs, business owners, and sellers in one location. This social networking site allows entrepreneurs to submit their pitches and seek partners or investors, investors to find companies to invest in, and business owners to find partners or someone to sell their company to.
