Java sits at the center of the platforms I build. Spring Boot runs the backend services and APIs, handling business logic, data access, and the core behavior of the system. Many of these platforms pair a Spring Boot backend with Angular on the frontend, forming structured web applications such as internal dashboards, operational platforms, and SaaS systems used by teams every day. Angular provides the application interface while the Java backend manages services, data, and integrations behind the scenes. Python also comes into play when automation or data workflows are needed. Small services and scripts written in Python handle background tasks, integrations, and operational processes that support the main platform. Java and Spring Boot handle the backend services, Angular runs the platform interface, and Python supports automation and background tasks.

I build scalable backend systems using Java & Spring Boot that handle real-world traffic without breaking.I also support Angular frontend development to deliver complete end-to-end web applications. With 6+ years of experience, I specialize in developing robust APIs, microservices architectures, and cloud-based systems that are reliable, secure, and built for production. If you're facing issues like slow APIs, poor scalability, or need a backend built from scratch. I can help you design and implement a solution that actually works under load.
