Capgemini | Senior Python Developer During my tenure at Capgemini, I worked as a Senior Python Developer with over 8 years of experience in designing, developing, and delivering scalable enterprise-grade web applications, backend systems, automation frameworks, and AI-enabled solutions for global clients across multiple industries. My role involved end-to-end ownership of backend architecture, API engineering, cloud deployments, performance optimization, and automation-driven business solutions. At Capgemini, I contributed to building modern, secure, and highly maintainable software systems that supported large-scale business operations. My responsibilities extended across the full software development lifecycle, including requirement analysis, solution design, development, testing, deployment, monitoring, and continuous improvements. Backend Development and Enterprise Application Engineering I played a key role in developing robust backend systems using Python and leading frameworks such as Django, Django REST Framework, FastAPI, and Flask. I was involved in building scalable web platforms and enterprise applications that served thousands of users with high availability and performance requirements. I designed and implemented modular backend architectures following microservices principles, ensuring better scalability, independent service deployment, and maintainability. My work included building RESTful APIs and service-to-service communication layers that enabled seamless integration between internal modules and third-party systems. I also worked on real-time application development using WebSockets, enabling live data streaming and instant communication features for business-critical applications. To support asynchronous processing and workload distribution, I implemented background task execution systems using Celery along with message brokers like RabbitMQ and Redis.
