Live Projects: WhataDeal https://whatadeal.events/ As a Senior Backend Engineer at WhatADeal, I designed and developed the core microservices powering our event management platform using Node.js and Nest.js. I implemented the Product Service with real-time inventory synchronization using Kafka, engineered the Booking Service's transaction system handling 10,000+ daily bookings with 99.9% reliability, and built the Promotion Service's discount engine. My performance optimizations through Redis caching and query tuning reduced API response times by 60% while maintaining system stability during traffic spikes. Working within the backend team, I contributed to our microservices architecture and introduced testing improvements that reduced production incidents by 40%. These systems supported the platform's growth to handling 50,000+ concurrent users and facilitated a 30% monthly increase in vendor adoption, demonstrating the scalability and robustness of the backend infrastructure I helped build.

In this role, I took on the responsibilities of a full-stack developer, contributing significantly to various aspects of the project. One of my key achievements was the creation of an affiliate frontend web application for CredPal, which played a pivotal role in attracting and onboarding over 45,000 new users within just four months. I also played a central role in introducing new features and enhancing existing ones within the credit card system. My multifaceted involvement included serving as the team lead for the loans module and participating in the payment team, where I skillfully integrated various payment solutions such as Paystack, Korapay, Monnify, and Remitta. Furthermore, I demonstrated my proficiency in data analysis and reporting by generating comprehensive reports using advanced SQL queries. To ensure a seamless transition and improve scalability, I took the lead in transitioning the system from a monolithic architecture to a microservices-based one. This project not only honed my software engineering skills but also allowed me to contribute significantly to expanding the reach and impact of the credit card company's services.

This application is dedicated to extending credit to both small businesses and individuals. During the project, my contributions were diverse and played a vital role in enhancing a lending application designed for both small businesses and individuals. I was responsible for optimizing the onboarding process and improving the registration module, focusing on streamlining the user experience. This ensured that the journey from sign-up to log in was smooth, efficient, and user-friendly. In addition to this, I implemented a robust phone number verification system, which significantly enhanced security and user verification. This system involved generating and sending authentication tokens to users via SMS, a critical feature in ensuring the identity of users. Furthermore, I simplified the sign-up process by introducing social authentication, allowing users to access the application using their social media profiles. This not only streamlined the registration process but also enhanced overall user convenience. My contributions extended to the analysis of users' social reputations, where I crafted a script to fetch data from platforms like Facebook, LinkedIn, and Twitter. This data was then used to calculate users' social reputations, resulting in a score that determined the maximum loan amount a user could qualify for. Lastly, I played an active role in troubleshooting and maintenance, addressing issues, resolving bugs, and extending the application's functionality with new features. Technologies: PHP (Yii), HTML, CSS, MySQL, and Git. PET ROJECTS: Banka App. http://dharmykoya.github.io/banka I developed a mini-project during my recruitment at Andela, demonstrating my skills as a software engineer.
