Experience
- Skaitmeninis, MBSolution Architect - Principal Backend EngineerEDUCATION AND E-LEARNINGDecember 2024 - Today (1 year and 6 months)
- designed and implemented a cloud-native, event-driven microservices architecture using Java 21 and Quarkus 3.x
- built reactive backend services with Vert.x and SmallRye Mutiny to handle high-concurrency workloads
- modeled domain-driven architecture with hierarchical MongoDB collections optimized for performance and scalability
- implemented Kafka-based event processing with idempotent operations and fault-tolerant workflows
- designed secure multi-service infrastructure with strict network isolation and token-based authentication
- ensured observability, resilience, and production-readiness across distributed components
--- - McLane Company (Enterprise Distribution & Logistics)Solution Architect / Principal Backend EngineerRETAIL (LARGE RETAILERS)May 2021 - October 2025 (4 years and 5 months)
- designed and led modernization of distributed backend systems supporting large-scale logistics operations and hight-speed repricing
- architected event-driven microservices (Kafka-based) to improve system scalability and decouple legacy components
- optimized concurrency and throughput in high-volume transaction processing pipelines
- implemented resilience patterns (idempotency, retry orchestration, failure isolation) to stabilize production systems
- collaborated with cross-functional teams (product, infrastructure, security) to align architecture with business constraints
