[Personal Project] Actu Sport Mundo - https://actusportmundo.com - has been a news platform since 2022, with a focus on African athletes. I developed the mobile app to be launched this December, available on Android and iOS. Its main features are sports news wherever Africans are involved but it also offers teams, championships, and other category preferences, so that user gets notifications based on their preferences. Additionally, it features a scores section akin to Google Search. It currently supports two languages (English and French).

Helped a hybrid team of twelve maintain and migrate a legacy VMS (TVS) to 12-FA multi-VMS (ALVEA). +1bn people served daily Kubernetes, Helm, Cloud Foundry, Docker, Spring Framework, Java 8/11, Angular, StencilJS, TypeScript, JavaScript, OpenID Connect, microservices, micro frontend, Jenkins, Ansible, TDD, DDD.

Member of the feature team rewriting the Risk-Adjusted Return on Capital (RAROC) platform MVP. I focused on the simulation microservice and leveraged Spring Framework and Domain-Driven Design to develop and test REST services that collect and organize data for the RAROC calculus microservice, and version simulations and their contextual data.

Societe Generale is a French bank, the largest in Europe, established worldwide. Member of the GTS Alerting team for their private cloud platform. Here are my major contributions to the project: + Re-engineer the Java-based microservice at the core of monitoring, based on Apache Flink with the goal of not repeating logic across the code base + Fix various bugs from v1 logic that caused more than 30 crashes per day in production environments + Design abstractions for Apache Flink data sources, for consistency and reuse across the service + Collect custom metrics sent to Influx DB and build live monitoring graphs with Grafana + Advocate for GitOps-based CI/CD and implement it using on-premise Jenkins, and some Python scripting, across environments & the multi-region cloud + Secured our pipelines & clusters by migrating secrets from Jenkins and Kubernetes secrets to Vault + Developed a Python-based microservice that integrates with the in-house ticketing system, to serve users preferring ticketing for resources monitoring alerts. I used Flask, Open API, OAuth, RabbitMQ, PostgreSQL and SQL Alchemy + Provisioning of “static” resources (PostgreSQL database, InfluxDB, AWS S3 buckets) using Terraform and Ansible As a result, we ingested 14.5 billion metric events daily, crossed with 11.3k monitoring rules (default and user-defined), produced ~26k violations (ACTIVE/INACTIVE) per day and, thanks to anti-flood, ~3k alerts daily. The Grafana boards & Apache Druid aggregated metrics provided insights to fine-tune performance further for Apache Flink within our clusters. Terraform and GitOps CI/CD made deployments a breeze.

Muuv Labs merged with Vi Labs and is now a Vi company. Their innovation labs help health and wellness companies develop the next generation of products, faster and more affordable than ever before. I enriched the back-office application with users and product information to help the support team, using GCP Cloud Build for CI/CD and Kubernetes for DevOps, Elastic Search for caching, PostgreSQL and NodeJS (Express.js).

Memority is a French startup which was absorbed by Accenture in 2018 until late 2023. It is also the product they develop: an Identity and Access Management (IAM) both as a Platform as a Service (Paas) & on-premise enterprise software. The multitenant solution featured flexible models, custom IAM workflows with BPMN, permissions & roles delegation, custom UI, in-app scripting, and integration with external tools (client APIs, LDAP, InWebo, SAML, OpenAM). I implemented many features in various microservices, from authentication to data model migration, through developing frontend widgets and integrating them with back office and backend APIs & dataset import and export. I did some CI/CD scripting in Jenkins, managed dependencies with Maven, containerization with Docker, data storage with PostgreSQL and MongoDB, backend with Spring Framework, database schema versioning with Flyway, frontend with Angular, and broker with RabbitMQ. + Memority received ISO27001 certification DevSecOps under SOC and “Les Cas d’Or” 2019 for IoT security. + It powered security around the Internet of Things (IoT) for renowned vehicle constructors + A demo delegated permissions over a flying drone, and the recipient took control right away, in-flight

Maximising front-end development expertise, I created an accountancy application and established a continuous deployment process through Google Cloud Run, with Nginx web server and Docker open platform. I also employed the use of VueX, Vue-router, SCSS/SASS and Tailwind CSS throughout the project. My key contributions included: • Delivered quality solutions 2-weeks into the project by picking up VueJS a week prior to starting.

As part of an e-commerce open-source project, the aim was to implement features across the sales pipeline and a DevOps process with Docker open platform, using various technological programs such as NestJS, OpenAPI, Angular 9 & Nebular theme, Postgres and Docker. My key contributions included: • Planned and led back-end/front-end software installation to strengthen sales pipelines.

With the use of Python, NodeJS, NL, Postgres, Open API 3, Sequelize, React and AWS, my role centred around building an application designed to customize menus, adapt to alternative ingredients and introduce complex nutritional formulae. My key contributions included: ♦ Built a nutritional PoC AI-based application to enable restaurants to tailor menus to customers.

I designed and built a range of microservices with supported data sources using Express, Redis, Swagger and Datastore in a full-stack development role. I produced integration specifications and unit test plans to successfully validate APIs, utilizing open-source testing frameworks such as Jest, Jasmine and Mocha. I instigated projects for container readiness, including the deployment of Kubernetes, Dockerfile and Docker Compose Files. I sustained a well-defined API gateway, developer server scripts and processes for production-grade maintenance programs.

Ran the printing house, supervising a team to provide a range of services to clients, including defect and issue resolution, ongoing maintenance and full replacement. Took ownership of financial management, accounting and store leadership. I discovered the entrepreneur lying in me.

Lead the IT department of a young integrated poultry group. I also assisted with the supervision of staff, budgets and system management. I worked with the founder and partners (including Belgium Nuscience, Italian Mancini & Cameroonian COMETAL) daily to understand the entire business plan and enable efficiency with IT software solutions. + Build the company website with WordPress, integrated with Google Analytics and Google Maps + Build a small intranet HR software to help aggregate and search through employees and candidates. I used AngularJS, MySQL and NodeJS (Express.js).

Secured internship as part of software engineering degree. I developed a web tool to help HR with the onboarding process by building AngularJS, Java, Spring Framework, and Twitter Bootstrap.
