Mohd Shahil

I’m a Java Backend Developer with 4 years of experience building scalable, secure enterprise applications for organizations in the Financial Services and telecom domains. I focus on delivering high-performance backend systems through strong API design, clean architecture, and reliable integrations.

Across projects and roles, I’ve worked extensively with Java (Java 8/17), Spring Boot, Spring MVC, Spring Data JPA, Hibernate, and microservices architecture. I design and implement RESTful APIs, including authentication and authorization with Spring Security, JWT, and Keycloak, while ensuring robust exception handling and application error management.

I optimize persistence and performance using MySQL and MongoDB, JDBC/JPA patterns, and database query optimization. I also apply Redis caching strategies to improve response times and reduce database load, and I integrate third-party services such as payment gateways and notification systems.

I deploy and support production systems using AWS and Docker, with CI/CD workflows backed by Git and GitHub. I’m comfortable with log analysis, thread dumps, heap dumps, and monitoring through Prometheus and Grafana, and I strengthen quality with unit/integration testing using JUnit and Mockito, plus Swagger/OpenAPI and Postman.
