Cloud and Software Engineer focused on building reliable systems, useful automation and practical AI integrations.
I work on backend services, serverless data pipelines, IoT integrations and internal tools that turn messy operational processes into maintainable software. My current work mixes production cloud infrastructure, connected devices, AI-assisted workflows and developer tooling.
- Building
git-health, an open source CLI for repository health checks. - Designing IoT data pipelines and serverless integrations with AWS, MQTT, Lambda, S3 and CloudFormation.
- Working with LLMs, RAG systems and workflow automation for engineering and operations.
- Improving reproducible technical projects with notebooks, tests, CI and clear documentation.

I am interested in small, useful tools that developers can run locally in minutes:
- repository quality checks;
- notebook reproducibility;
- environment and configuration validation;
- IoT and MQTT diagnostics;
- automation scripts that remove repetitive work.
