Within the payment team, I participated in the development of a secure and scalable payment solution, integrating various payment methods as well as inter-company and cross-border flows. The project was carried out using Agile methodologies, with an approach focused on pair programming and mob programming, and a continuous effort of refactoring to ensure code quality. Unit test coverage reached 80% on the C# side and 70% on the Typescript/Vue side, and over 1,000 integration tests were implemented on Postman.

My contribution:

- Development of new front-end and back-end features

- Participation in the design and development of the new authorization version and its implementation for all partners

- Participation in the design and development of a new payment method eligibility management system per partner

- Integration of new payment partners

- Migration of projects from .NET 6 to .NET 8

- Migration of a VueJS project from Webpack to Vite and from Vuex to Pinia

- Configuration and development of front-end unit tests with Vitest

- Development of a Kafka-Elasticsearch POC to generate performance indicators (KPIs) for transactions

Arrowsphere is a cloud service management and distribution platform. It acts as an intermediary between cloud service providers (Azure, Amazon, etc.) and cloud service resellers. I joined the team responsible for the provider portal and provider catalog management. I also worked on the cross-team authentication and authorization system. Projects are divided into microservices and libraries, run on a fully serverless AWS architecture, and use a Git workflow based on the master branch only (and feature branches). With this Git workflow, a continuous integration and deployment (CI/CD) pipeline allows QA to autonomously merge and deploy validated pull requests.

AWS Services used:

- ApiGateway

- CloudFormation

- CloudFront

- CloudWatch

- CodeArtifact

- Cognito

- DynamoDb

- IAM

- Lambda

- OpenSearch (Elasticsearch)

- S3

- SES

- SNS

- Step Functions

Technologies:

- Nodejs 18

- Typescript 4

- Vue 3

- Eslint

- Mocha

- Newman

- Cypress

- Git

- Shell

My contribution:

- Design and development of new features across the entire stack of our project

- Updating our import tools to cover 100% of provider offerings

- Improving our authorization and authentication provider to manage policies, allowing for easier grouping and assignment of rights

- Participation in a cross-team project for autonomous integration of new providers

- Refactoring and improvement of existing code (design patterns, performance enhancements, code coverage)

- Migration of all repositories from Node 12 to Node 18

- Implementation of a common set of ESLint rules, common build/deployment scripts, and common package workspaces across all repositories

I joined the BMC team on a project to digitize merchant management (+300K affiliates) to optimize payment services (+300M transactions/year).
