About John Selvaraj Arulappan
Lead Application Developer at Adp Celergo
With over 15 years of experience in software development, I specialize in Microsoft Dynamics 365, Power Platform, and CRM solutions. My expertise lies in designing and implementing scalable microservices architectures using .NET Core, RabbitMQ, Docker, and Kubernetes ensuring systems that are secure, reliable, and high-performing.
I have successfully led large-scale CRM migrations, including a cost-efficient upgrade from Dynamics CRM 2011 to 2016, and optimized workflows through custom plugins and .NET integrations. My focus on building secure APIs, applying encryption and hashing techniques, and adopting clean architecture principles ensures robust solutions for complex business needs.
Beyond back-end engineering, I bring strong front-end integration skills with Angular and micro-frontend frameworks, along with hands-on experience in setting up CI/CD pipelines using Azure DevOps, Jenkins, and Bitbucket. My deep understanding of containerization and orchestration enables me to deliver solutions that scale seamlessly across global environments. I enjoy bridging technology with real-world impact, and I thrive in collaborating with stakeholders to deliver tailored solutions that drive measurable business success.
As a mentor, I’m committed to sharing practical knowledge, guiding professionals through complex technical challenges, and helping them grow their careers with confidence in both technology and leadership.
