I have experience implementing Microsoft Power BI functionality in Node.js and Express, as well as integrating BigQuery for data analysis. I've designed and managed API modules for two in-house applications, Qufree and Trakwa, available on the Play Store. Additionally, I've worked as a backend developer for a third-party, focusing on customer-impacting features, unit testing, and bug fixing.I've also designed and built multiple microservices, including UAAM (User Authentication and Authorization Management), FMS (File Management Service), PMS (Product Management Service), NMS (Notification Management Service), and CUS (Common Utils Service). These services can be independently injected into any existing or new software system.In terms of planning and requirement analysis, I've been involved in designing new features and functionalities. I've successfully integrated two-way communication on WhatsApp and Interactive Voice Response (IVR) systems via webhook and deployed them. Additionally, I've developed an Email notification system for handling transactional, system info, and promotional emails for all clients on the platform.I've also worked on a Network Management Project (COBO) as a full-stack engineer, integrating Google Maps API and other customer requirements.
