What I'm looking for

I’m looking for a backend-focused role where I can build reliable pipelines and performant services, work with modern AI/LLM systems, and continuously improve quality with testing and CI/CD—preferably on scalable products with real impact.

I’m a Backend / Full-stack developer who loves turning messy data and ideas into reliable systems. At Pappers, I developed ETL pipelines with Node.js, TypeScript, and SQL (processing up to 45M+ records) and refactored backend services using SOLID principles to cut response times by up to 99%.

I also work on modern AI-driven backends, building LLM pipelines (60–70% average accuracy; up to 80–90% on targeted tasks) and designing an LLM evaluation server using the LLM-as-a-Jury approach. Previously at Expensya, I contributed to a B2B SaaS expense management platform used by 600K+ users and 6K+ clients using ASP.NET Core, C#, and SQL Server—optimizing queries, improving API reliability with a retry mechanism, and strengthening quality with unit and end-to-end tests.
