Architectural Guidance & Strategic Migration
Java Developer/ Tech Lead
Java Developer/ Tech Lead
Architectural Leadership & Strategic Migration: Spearheading the migration of a large-scale Enterprise Legacy platform from Azure Services to AKS (Azure Kubernetes Service), ensuring high availability and seamless transition of critical logistics business logic.
Event-Driven Architecture (Kafka): Designing and implementing high-throughput asynchronous communication using Apache Kafka.
Kafka Streams: Leveraging Kafka Streams and event-sourcing patterns to ensure data consistency and decoupling of warehouse management modules.
System Design (DDD & CQRS): Architecting complex domain models using DDD and CQRS, specifically focused on solving concurrency and scaling challenges in global logistics.
Infrastructure & Cloud Automation (IaC): Leveraging Terraform and Helm charts to automate the provisioning and management of production-grade Kubernetes (AKS) environments, focusing on infrastructure stability, pod performance, and Kafka consumer group scaling.
Technical Governance: Driving architectural consistency and mentoring the team in building robust, testable microservices (Java 21, Spring Boot 3.4).

Leading project for Warehouse Management
Java Developer
Java Developer
High-Throughput Event Processing: Engineered a system for processing events from TMS (Transport Management System) using Apache Kafka and Avro serialization, ensuring high data consistency and schema evolution safety.
Resilience Engineering: Designed and implemented complex Kafka Retry Strategies (Retry/DQL topics) and Transactional Outbox patterns to guarantee message delivery and system reliability under heavy load.
Performance Optimization & Load Testing: Conducted rigorous load testing and "to-the-bone" microservice optimization (Java 21, Spring Boot 3).
Fine-tuning: Optimized JVM parameters and Kafka consumer configurations to achieve sub-second processing latency.
Polyglot Persistence: Managed diverse data storage solutions, optimizing queries for MS SQL Server and MongoDB to support high-concurrency logistic workflows.
