⇢ End-to-end development of the back-end API that powered Grandvision subscription payment and customer care portals, using C#, .Net, Zuora, and Vue.js, this product powered 7,200 stores owned by the client and led to over 30% increase in annual subscription and renewals.
⇢ I developed a total of 9 Medusa Js and Strapi CMS plugins, using Node.js and typescript, to manage features including payment integration with Mollie, migration of existing clients from Odoo to medusa js, search and filter functionality for product and text based search using Algolia, and other B2b features to modernize EKI’s e-commerce solution for manufacturing rubber, plastic and foam across europe.
⇢ Automated Europarc’s in-house Smartsheet for managing real estate sales, enabling automatic updates to their sales websites and seamless synchronization with other site listings. This led to an increased efficiency in managing their sales listing as they only need to work on the sheet and all the data is synchronized to all the websites.

⇢ Modernized the backend of the company's mainstream product from PHP to Node.js using Nest.js, Typescript, RabbitMQ, Reddis, and Mysql database.
⇢ I led the design and implementation of a message queue management system using RabbitMQ, which ensured that data was adequately processed. This increased the speed of the dashboard by 5 folds.
⇢ I spearheaded the redesign of the entire cloud infrastructure from manual deployment on AWS EC2 to using Pulumi as infrastructure as code provider and deploying all services on AWS ECS Fargate.
⇢ I implemented CI/CD processes using Bitbucket pipelines to automate the deployment of the entire infrastructure using Pulumi cloud.

⇢ I Led the design and implementation of a well-integrity management system, which collects and analyzes data from oil wells to compare it against globally accepted safety standards and recommendations. This increased the overall safety and integrity of oil wells by over 25% thanks to the system recommending action points to the engineers regularly.
⇢ I spearheaded the design of SEPAL PVTRMS software, a desktop software used for digitizing oil PVT laboratory reports.
⇢ Designed and implemented a C# based algorithm for petroleum production forecasting that integrates economic forecasts based on oil production and the inherent constraints surrounding oil production. The license for this piece of software was sold for $25,000 per annum for more that 5 clients at the time.
⇢ Implemented backend APIs for EPS, a software requested by the NPDC for managing budgets based on UAP standards and expected yearly or monthly production for all joint venture partners. This piece of software sold for $1.3M.
