Technical Leadership & Full-Stack Expertise - I've demonstrated great technical leadership by transforming a legacy CRM system into a modern, scalable microservice architecture using .NET Core and Angular. My expertise spans cloud infrastructure design with Azure DevOps, Infrastructure as Code principles, and PostgreSQL optimization that significantly reduced costs while maintaining performance. I've built comprehensive solutions including advanced automation modules, JWT authentication systems, multi-channel communication platforms, and pioneered event-driven architecture using hexagonal patterns and CQRS for cross-domain data management. My ability to integrate cutting-edge AI technologies like Mistral AI for intelligent conversation summarization showcases my innovation in leveraging emerging technologies for business value.

Strategic Vision & Team Development - Beyond technical skills, I am doing great at strategic decision-making, having successfully convinced leadership to adopt microservices architecture and established clear domain boundaries that balance technical excellence with business needs. My leadership extends to mentoring junior developers on complex architectural patterns, conducting workshops, and delivering comprehensive AI implementation training. I've consistently demonstrated the ability to prepare forward-thinking solutions, such as mobile development alternatives addressing policy constraints, while maintaining rigorous development standards in fast-paced startup environments. My approach balances rapid delivery with sustainability, ensuring technical debt management while transforming legacy systems into market-ready products that appeal to modern customers.

Backend Development - I served as a backend developer for Gaming1's betting sites within a team of fifteen developers, where I developed robust import/export modules in C# and .NET for ticket management systems, enabling QA teams to utilize production data for realistic automated testing scenarios. I implemented critical backend solutions for heavily regulated gaming environments, ensuring strict compliance with stringent industry regulations while working within a monolithic architecture planned for future decomposition. My technical contributions included proactive preparation for planned architectural transformation through comprehensive training on containerization with Docker, and I introduced Kubernetes orchestration concepts to experienced developers, demonstrating practical implementation approaches tailored to our existing systems.

Operations Leadership & Cross-Functional Collaboration - I took on significant operational responsibilities, participating in on-call rotation to provide critical support for Linq American markets across multiple time zones, ensuring 24/7 system reliability. I coordinated cross-functional incident response involving internal sports analysis teams and infrastructure specialists during system outages, while creating detailed incident reports documenting root causes, resolution approaches, and preventative measures for future reference. My leadership extended to organizing training sessions for colleagues with varying experience levels, including senior developers with 15+ years of experience, and I effectively navigated complex process environments dictated by strict regulatory requirements while maintaining effective communication across organizational boundaries and managing interconnected projects with three additional development teams.

Frontend Development & AI Consultancy - I participated in migrating a legacy ASP.NET application to Angular, modernizing the user interface while maintaining core functionality and business logic. I initiated technical discussions on Angular state management approaches, comparing BehaviorSubject implementation within services against contemporary state management libraries, and established Angular best practices through collaborative team workshops that created standards guiding future frontend development projects. My AI expertise includes completing an advanced university certificate in Artificial Intelligence at UMONS, gaining comprehensive knowledge across multiple AI disciplines and mastering fundamental concepts including interpolation techniques, image processing/classification methodologies, and reinforcement learning approaches. I assisted the CEO in "Tremplin IA" consultation meetings, helping diverse businesses identify strategic AI implementation opportunities to enhance their operations.

Client-Focused Innovation & Cross-Industry Consultancy - I developed key features for a public administration's timber management CRM system, demonstrating strong attention to specialized industry requirements while maintaining close collaboration with client stakeholders throughout the development process to ensure alignment between technical implementation and business objectives. I delivered iterative improvements based on direct client feedback, resulting in high user satisfaction and system adoption.
