Professional Summary

Senior backend engineer with 5+ years building production APIs, microservices, and cloud-native systems. I work from explicit boundaries — ports and adapters, bounded contexts, and contracts you can test — not from framework magic.

Recent work spans multitenant NestJS services on AWS, event-driven architectures with Kafka, and integrations across compliance and logistics domains. I also mentor teams on testing, CI/CD, and maintainable delivery.

Focus areas

Backend Architecture
Microservices with Clean Architecture, hexagonal patterns, and CQRS where the domain requires it.
Cloud-Native Development
AWS in production — Lambda, ECS, API Gateway, DynamoDB, and CI/CD pipelines for multitenant delivery.
Distributed Systems
Resilient messaging with Kafka, gRPC, and idempotent consumers for high-availability workloads.
Performance Optimization
Latency and cost tuning through caching, query design, and observability-driven iteration.
