{"entity":"person","person":{"name":"Pavel Tishchenko","role":null,"level":"Senior","country":null,"summary":"A backend-focused engineer comfortable across Python ML inference and Java/Spring backend systems at a senior, pragmatic level. The strongest proven skill is designing and testing production-grade APIs and domain services, evidenced by the FastAPI inference service with metrics/caching and the Java transactional services with idempotency and optimistic-locking tests. There is less public evidence for advanced operational patterns like distributed queues, circuit breakers, secret rotation workflows, or documented DB migration histories.","skills":[{"name":"Python","group":"Languages","level":"Senior","since":null},{"name":"Java","group":"Languages","level":"Senior","since":null},{"name":"C++","group":"Languages","level":"Senior","since":null},{"name":"SQL","group":"Languages","level":"Not selected","since":null},{"name":"Bash","group":"Languages","level":"Not selected","since":null},{"name":"FastAPI","group":"Python","level":"Senior","since":2024},{"name":"Pydantic","group":"Python","level":"Senior","since":null},{"name":"Uvicorn","group":"Python","level":"Senior","since":null},{"name":"Spring Boot","group":"Java","level":"Senior","since":null},{"name":"Testcontainers","group":"Java","level":"Senior","since":null},{"name":"CMake","group":"C++","level":"Senior","since":null},{"name":"LLM","group":"AI/ML","level":"Middle","since":2024},{"name":"BERT","group":"AI/ML","level":"Middle","since":2024},{"name":"vLLM","group":"AI/ML","level":"Middle","since":2024},{"name":"RAG","group":"AI/ML","level":"Middle","since":2024},{"name":"NumPy","group":"AI/ML","level":"Middle","since":null},{"name":"PyTorch","group":"AI/ML","level":"Not selected","since":null},{"name":"Scikit-learn","group":"AI/ML","level":"Not selected","since":null},{"name":"Transformers","group":"AI/ML","level":"Not selected","since":null},{"name":"XGBoost","group":"AI/ML","level":"Not selected","since":null},{"name":"CatBoost","group":"AI/ML","level":"Not selected","since":null},{"name":"Airflow","group":"AI/ML","level":"Not selected","since":null},{"name":"MLFlow","group":"AI/ML","level":"Junior","since":2026},{"name":"Deep Learning","group":"AI/ML","level":"Middle","since":null},{"name":"MLOps","group":"AI/ML","level":"Middle","since":null},{"name":"NLP","group":"AI/ML","level":"Junior","since":2026},{"name":"FAISS","group":"Databases","level":"Middle","since":2024},{"name":"pgvector","group":"Databases","level":"Middle","since":2024},{"name":"PostgreSQL","group":"Databases","level":"Senior","since":null},{"name":"Redis","group":"Databases","level":"Senior","since":null},{"name":"Apache Kafka","group":"Databases","level":"Not selected","since":null},{"name":"CI/CD","group":"DevOps","level":"Junior","since":2024},{"name":"Prometheus","group":"DevOps","level":"Senior","since":null},{"name":"Docker Compose","group":"DevOps","level":"Senior","since":null},{"name":"Git","group":"DevOps","level":"Not selected","since":null},{"name":"Rest API","group":"DevOps","level":"Not selected","since":null},{"name":"Docker","group":"DevOps","level":"Junior","since":2026},{"name":"SLI/SLO/SLA","group":"DevOps","level":"Not selected","since":null},{"name":"Pytest","group":"QA","level":"Junior","since":2024}],"photo":"https://alion.io/storage/2026/0720/3da1a1adc2.256.webp","url":"https://alion.io/user/pavel-tishchenko"},"contact":"Through Alion only: the person decides whether to answer.
