Project 1 – Replacing legacy system (HealthTech): • Delivered Kafka proxy cluster (270K+ msg/min, <300 ms latency). Automated Kubernetes via Terraform (<60 s provisioning) and integrated Terraform state into GitHub CI/CD (AWS S3). Ensured versioned, reliable infra updates and team alignment. Project 2 – Global platform (E-commerce): • Implemented Kafka draft topics, extended Terraform provider, optimized Hibernate queries, led 20+ tech interviews and mentored engineers across distributed Agile teams.

Responsibilities: • Designed and deployed cloud-native, event-driven systems on AWS. Built high-performance Java microservices for on-premise event handling, led demos, workshops, and collaborated with international cross-functional teams and stakeholders. Achievements: • Integrated ACD & WFM systems, strengthened security (KMS, IAM, auto rotation), automated CI/CD (99% success), ensured 99.9% uptime for 1B+ req/month, fixed JVM leaks, improved scalability, and enhanced monitoring (Prometheus, Grafana).

• Developed a scalable Java microservice for processing fitness activity data from an Apache Kafka cluster, enabling horizontal scaling to 15+ instances. • Configured and optimized PostgreSQL with read replicas to achieve 99.9% high availability and data consistency. • Implemented load balancing with Nginx among 15 microservices, improving system throughput and reducing peak-time downtime by 90% through resilient, distributed architecture.
