Senior Backend Engineer · Core Engineer at Pashouses
Backend systems in Python and FastAPI, PostgreSQL performance and schema design, CI/CD with GitHub Actions and Docker, observability and reliability in distributed services. Currently exploring Rust for performance-sensitive workloads.
Focused on integrating LLM-powered features into backend systems with an emphasis on reliability and consistency. Experience designing services that interact with LLM APIs while treating them as non-deterministic components within a larger system.
Approach includes controlling output behavior through prompt design and structured responses, ensuring outputs remain coherent, predictable, and aligned with expected system behavior. Emphasis on validation, fallback strategies, and maintaining consistent user experience rather than relying on raw model output.
