Hiring Manager

Dear Hiring Manager,
Engineering teams need backend architecture that scales gracefully and is a joy to work with. At Pocket FM, I migrated legacy services to a microservices model, reducing latency by 40% and improving deployment frequency to multiple times per week. Hireginie's focus on intelligent hiring solutions needs that same blend of reliability and developer experience.
I have deep expertise in AWS, Docker, and Kubernetes, ensuring that the systems I build are not only performant but also maintainable. While leading backend initiatives at Pocket FM, I established CI/CD pipelines and automated testing that improved our code quality metrics significantly.
Prior to Pocket FM, I architected the backend for CodeAnt AI's hiring platform, collaborating closely with data scientists to productionise algorithms while keeping the API snappy for recruiters. Balancing machine learning pipelines with user-facing endpoints taught me how to make thoughtful tradeoffs.
