Milan Aleksić

Backend founding engineer of Soda, working on Soda Cloud SaaS. Programming languages I used were Java, Python and Go.

Became the company’s go-to backend engineer and MySQL performance guy. Helped scale the company 100x in both customers and revenue over 5 years, all without high-profile incidents in the Soda Cloud product.

Had a multi-hat impact on the organization through domain, infrastructure, and system design. Maintainer of the Soda Kubernetes agent, Vault Decrypter, warehouse source preparation, public API, OpenAPI generator, custom DI/DB framework, and several other complex features and mini-services.

Developed an internal platform CLI tool (dopy / dogo) for automating many painful DevOps tasks. v1 was in Python, v2 in Go (integrating APIs from AWS, Okta, Datadog, Kubernetes, Soda Cloud, using SQLite and Perfetto).
