Marin Tomic
@marintomic
I am a senior backend software engineer specializing in .NET, cloud-native architectures, and scalable serverless systems.
CroatiaWhat I'm looking for
I am a motivated and detail-oriented backend software engineer with 7+ years of experience building scalable, cloud-native systems and modernizing legacy platforms. I focus on clean architecture, performance optimization, and continuous delivery.
I have led serverless backend architecture and development using .NET Core, AWS Lambda, DynamoDB, SQS and SNS, and I built Docker-based CI/CD pipelines in Buildkite with Terraform and Makefile to orchestrate safe, version-aligned deployments. I drove a monolith-to-microservices migration on .NET and Azure, replacing MSMQ with RabbitMQ, MSSQL with Postgres and applying CQRS, Outbox and Saga patterns.
I also modernized legacy systems on AWS, worked on embedded C/C++ projects and AR/VR integrations, and implemented observability with Datadog and modular services via shared NuGet packages. I enjoy collaborating in remote teams to deliver reliable, maintainable systems that scale.
