Automated and implemented backup and recovery procedures for inventory management systems that resulted in high software availability.
Stored, retrieved, and manipulated data for close analysis of PostgreSQL database performance across specific periods. Consulted with network engineering staff to evaluate hardware and software requirements for new system development.
Oxus HRIS is a human resource information system that helps organizations automate the part of its human resource department that can be digitalized, it manages payroll, 401k, queries, loans e.t.c. I worked on migrating this huge software from Django 1 to Django 2 and Python 3. The project was very fun and full of experience because of migration from a deprecated Python 2 to the new Python 3. After Migration, I then went on to manage the app for 3 further months to assist the customers to migrate to the new app which now has more features, we were also able to achieve 2x more speed in request fulfillment.
Smcompliance is a platform that helps organizations curb social security risks and corporate espionage. While working on Smcomplaince, I used the Akka stack of Akka streams, Akka HTTP, and Akka persistence to handle streaming events and MongoDB as a data store. Smcompliance makes use of Kafka as an RPC to communicate with different services in the stack, and we were able to process hundreds of thousands of data daily through our data pipelines. I worked on web scraping processes to enrich and monitor the activities of the organization across many social platforms. I also used Akka streams to stream social media posts in realtime, send it to an integrated RPC using Kafka and subsequently to machine learning algorithms which then store the aggregations and results in MongoDB after predictions and segmentations.
Amana Market is a marketplace for agricultural produce, it connects farmers in the most remote part of Nigeria and also those in the urban cities to potential buyers of the products. This software is a full-scale marketplace that includes product delivery, aggregations from many farmers to fulfill IPOs, and a tracking system to track purchases and its delivery as it embarks. The platform was built using the Play framework, I worked as an engineer to design and translate the business logic of the purchases tracking and delivery system to a robust system that serves farmers and farm produce buyers across Nigeria, I also worked on a proof of concept architecture design for migrating the monolithic application to a distributed microservices platform which is currently in development.
