Julie Soni

I’m a Senior Full Stack Developer with 11+ years of experience designing, developing, and delivering enterprise-scale applications across Banking, Financial Services, and Business domains. I lead critical initiatives end-to-end, from backend and frontend delivery to modernization and performance optimization. I’m also experienced working in Agile/Scrum, including prior ScrumMaster responsibilities.

My core expertise spans Microsoft technologies including .NET Core, ASP.NET Core, C#, Web APIs, and REST services, along with microservices architecture. On the frontend, I build with Angular (12+), TypeScript, and JavaScript, and I work with SQL Server and Oracle/PL-SQL for reliable data handling. For cloud and delivery, I’ve used AWS and Azure alongside CI/CD pipelines and DevOps tooling.

At Barclays, I led development and maintenance of treasury systems handling 70+ data feeds, improving stability and performance. I migrated the application architecture to an AWS-based hybrid model, and implemented CI/CD pipelines using TeamCity, Nexus, and Nolio tools—reducing deployment time by ~50% and minimizing manual errors. I also built monitoring dashboards and delivered high-impact solutions for stakeholders, including large-scale regulatory Ring-Fencing across multiple legal entities.

Since Jan 2023, I’ve worked as an Independent Consultant/Freelance Full Stack Developer, designing and deploying a full-stack booking platform with ASP.NET Core and Angular, secure authentication, and payment integration. I focus on scalable architecture, responsive UI, API development, and reliable operations—continuously improving database performance, transaction stability, and user experience.
