The existing monolithic e-commerce platform was struggling to handle peak traffic during sales events, experiencing frequent downtime and poor user experience. The system needed to scale from handling 10K concurrent users to 100K+ during Black Friday sales.
Implemented a microservices architecture using Spring Boot and Kubernetes, with separate services for user management, product catalog, order processing, and payment handling. Introduced Redis for caching, Kafka for event streaming, and implemented circuit breakers for resilience.
Financial services company needed real-time fraud detection and transaction processing system capable of analyzing millions of transactions daily with sub-second latency requirements while maintaining strict compliance and audit trails.
Built event-driven architecture using Kafka Streams for real-time processing, implemented machine learning models for fraud detection, and created comprehensive audit logging system. Used MongoDB for flexible document storage and PostgreSQL for transactional data.
Full-stack Java development using Spring Boot, microservices architecture, and modern frameworks. Specializing in scalable enterprise applications with high availability and performance requirements.
Cloud-native application development and deployment using AWS, Azure, Docker, and Kubernetes. Implementing CI/CD pipelines and infrastructure as code for reliable, scalable deployments.
Leading development teams, establishing best practices, and mentoring developers. Experienced in agile methodologies, code reviews, and technical decision-making in enterprise environments.
Legacy system modernization, API integration, and data migration services. Helping organizations transition from monolithic to microservices architecture with minimal downtime.
I specialize in Java ecosystem technologies including Java 8-23, Kotlin, Spring Boot, Spring Cloud, Hibernate/JPA, and modern frameworks. For databases, I work with PostgreSQL, MongoDB, and Oracle. I'm experienced with cloud platforms (AWS, Azure), containerization (Docker, Kubernetes), and messaging systems (Kafka, RabbitMQ).
I follow domain-driven design principles to identify service boundaries, implement API-first design with comprehensive documentation, ensure proper service communication patterns, and establish monitoring and observability. I also focus on data consistency strategies, circuit breaker patterns for resilience, and automated testing at all levels.
I have led teams ranging from 3 to 15 developers across multiple time zones and cultures. My leadership approach includes mentoring junior developers, establishing coding standards and best practices, facilitating technical discussions and decision-making, implementing agile processes, and fostering a collaborative team environment focused on continuous learning.
I implement comprehensive testing strategies including unit tests, integration tests, and end-to-end testing. I enforce code review processes, use static code analysis tools, follow SOLID principles and design patterns, maintain clear documentation, and establish CI/CD pipelines with quality gates to prevent issues from reaching production.
I start with comprehensive monitoring and profiling to identify bottlenecks, optimize database queries and indexing strategies, implement appropriate caching mechanisms (Redis, in-memory caching), tune JVM parameters for optimal performance, and design efficient algorithms and data structures. I also focus on horizontal scaling strategies and load balancing.
I use the strangler fig pattern for gradual migration, implement API gateways for seamless integration, ensure comprehensive testing during transition phases, maintain backward compatibility where necessary, and plan phased rollouts with rollback strategies. The goal is to minimize business disruption while modernizing the technology stack.
