P
Hi, my name is Chibuikem Prince Chisomaga and I'm a Software Engineer who loves building finance-based, high-performance business, and blockchain-related solutions.
I have over 6 years of software engineering experience and an excellent understanding of JavaScript, PHP, Solidity, Typescript, Nodejs, MongoDB, Expressjs, Nest, MySQL, Postgres, Docker, Kubernetes, RabbitMQ, Sequelize, GraphQL, Redis, and design of highly available and scalable microservice applications.
My Hobbies are reading (Bible & Other books), praying, WWE, basketball and listening to podcasts during my free time. I also enjoy public speaking, mentoring, group discussions, and working with teams.
Fintech API
I have led software teams to build fintech web and mobile applications.
On those projects, I oversee the architectural designs, their Implementations, and the back-end implementations of the design.
At the backend, I proffered and implemented solutions to lots of challenges that have to deal with concurrency of wallet operations(debit and credit), payment security, double spending, and high application availability.
Cryptocurrency Mining API
I have built several mining APIs for cryptocurrency staking and investments like https://miningcyphers.com.
I built a special algorithm that receives a given amount of crypto from users and over a given period of time returns a higher value based on the hashing rate selected by the user and set for the staked value.
One great lesson and challenge on this project was managing and manipulating large decimal numerical values, and computing them with a reliable result.
Real-estate and E-commerce API
I have built real estate and property commerce projects. The project controls sales, purchases, and leases of houses, land, and other properties.
This project had a search engine that filters and handles a very large dataset.
I learned how to work on, transport, and manipulate large datasets without reducing the speed, performance, and availability of an API.
