Need a reliable senior Java developer who delivers scalable, production-ready solutions? I help companies build and modernize enterprise applications with 14+ years of hands-on experience.
What I Bring to Your Project:
I specialize in developing robust backend systems using Java and Spring Boot, architecting microservices that scale, and integrating modern cloud platforms (AWS, Azure). Whether you need to build a new application from scratch, migrate legacy systems to cloud-native architecture, or enhance existing platforms with new features
My Technical Expertise:
- Java (14+ years), Spring Boot, Microservices Architecture
- Cloud platforms: AWS, Azure (Azure Solutions Architect certification in progress)
- Frontend: React, Angular for full-stack delivery
- Data Engineering: Apache Spark, Apache Iceberg, Apache Airflow
- DevOps: Kubernetes, Docker, CI/CD pipelines
- Databases: SQL, NoSQL, distributed data systems
What Makes Me Different:
I combine deep technical expertise with financial services domain knowledge, having worked on mission-critical banking applications. I don't just write code—I architect solutions that solve real business problems. I communicate clearly with both technical teams and business stakeholders, ensuring everyone stays aligned throughout the project.
Projects I Typically Handle:
✓ Backend API development and microservices architecture
✓ Legacy system modernization and cloud migration
✓ Full-stack application development (Java backend + React/Angular frontend)
✓ Data pipeline engineering and ETL solutions
✓ Performance optimization and technical debt reduction
✓ Team collaboration on large-scale enterprise projects
My Approach:
I focus on delivering value quickly through iterative development, maintaining high code quality standards, and ensuring comprehensive documentation. I'm comfortable working independently or integrating with your existing team, adapting to your processes and tools.
