Automated Fulfillment Service

Launched a service that allowed fulfillment service to manage their orders through a dashboard instead of using their existing FTP solution.

A team of developers and business analysts were given this problematic situation at a big fulfillment center. At that point, they received their orders through a manual file system and then conveyed them to UPS and DHL through an FTP system.

At the end of the analysis, we built a cron-managed system on MuleSoft that relied upon an API. The cron job pulled customer orders from the different systems at a defined frequency and sent them automatically to the fulfillment center as well as DHL and UPS through APIs to prepare themselves to fulfill them. Once the orders were packed, DHL and UPS also received notifications to pick them up and sent out notifications when they delivered the packages.

Though common in 2021, this integrated system wasn't as popular at the time of this project, and maintaining existing business roles wasn't quite easy while making such a major transition.

Certificate Management on Blockchain

As the first hired person, I divided the project into manageable tasks and decided which engineers would be required to meet the deadline and budget. I laid out the entire engineering stack and architecture that we had to adhere to.

Managed to get two developers for the UI and integration in India, a blockchain consultant in Cameroon, and a mobile development agency in Columbia. I did all the DevOps and project and product management. We succeeded in delivering the project within time and budget.

This project was challenging as no one on the project but the consultant had experience with blockchain. I quickly used my engineering background to grasp the required architecture and handled communication through APIs. Once we knew the protocols, implementation became rapid following microservice architectural patterns.

I defined the architectural structure to follow with buy-ins from the blockchain consultant. This was developed using .NET and tested with a Cucumber Selenium framework.

Doctor-Patient Relationship Management Solution

http://www.dprm.io

Managed a team of three back-end developers, two mobile developers, one front-end developer, and two QA engineers. Defined and prioritized user stories and bugs based on stakeholder and user feedback and launched the project within budget and time.

This project was critical as it involved heavy PII data management. I had to work with domain experts to get more knowledgeable of the medical field and its requirements. Based on the knowledge gathered, I was able to break down business requirements better and convey the needs in a technical vocabulary to the development teams.

We had to pass multiple security testing and work with the team to prioritize and quickly fix the few issues mentioned from a data security and penetration testing perspective. We launched the project on both web and mobile on time and within budget.
