Qartivus develops enterprise-level software and SaaS solutions for startups and growing companies that require reliable and scalable production systems. Our expertise lies in three main areas: creating new SaaS platforms from the ground up, developing backend APIs and machine learning pipelines, and providing Code Rescue services for teams dealing with inherited codebases filled with technical debt or AI-generated shortcuts that are difficult to expand safely. Each project comes with complete code ownership, well-documented architecture, and GDPR-compliant design. We avoid black boxes and unexpected issues. We are discerning in our project selection, ensuring that each client receives direct senior involvement from the architecture stage through to the final delivery.
