Overview
A backend-focused LLM-inference engineer at a mid-to-senior level who builds asynchronous, production inference pipelines integrating LLMs and audio transcription. The strongest proven skill is building reliable async pipelines and integrations - demonstrated by the Mango client parsing, worker implementations, transactional outbox and comprehensive pytest coverage (e.g., app/clients/mango.py, app/services/*_worker.py and tests/*). There is no evidence of custom model training, experiment tracking, GPU/quantization work or original research-level ML architecture in public code.

Overview
A backend-focused engineer at a solid middle level who independently builds end-to-end features integrating LLMs, embeddings and data ingestion across small services. The strongest proven skill is building RAG-style pipelines and LLM integrations, evidenced by the ingest and chat API routes that create embeddings, store chunks and perform similarity lookup (chatbot-builder/app/api/ingest/route.ts and chatbot-builder/app/api/chat/route.ts). The public code, however, lacks migration history, formal testing, structured observability and advanced scalability or transactional design.

Backend • Middle • 5+ years exp • Moscow, Russia • In office, Partially remote, Fully remote • Actively seeking • English: B1
Overview
A pragmatic backend engineer at a senior level who repeatedly ships API services, LLM integrations and device-sync logic with substantial test coverage. The strongest proven skill is building resilient AI-backed service paths and integration guards (timeouts, hedges, retries, quota and streaming) evidenced by llm transport tests, hedge/timeouts in server code and background parse adoption logic (relo_dojo llm tests, Driftora backgroundParses and llm/transport tests). Code shows careful DB migration and encryption work but lacks public evidence of large-scale distributed systems (multi-region, service mesh) or infra-level SRE artifacts.

Backend • Middle • 4+ years exp • Novosibirsk, Russia • In office, Partially remote, Fully remote • Actively seeking • Relocation
Overview
A backend-focused engineer with strong hands-on experience implementing distributed-consensus components and a second skillset in Java-based multiplayer game code; the Raft roles, transport layer and custom storage provide the strongest proof. The clearest proven skill is building a Raft implementation with concurrent replication and HTTP-based RPC, evidenced by core role implementations (leader/follower/candidate), transport sender/receiver and storage (LockStorage). The public code does not show production-grade API governance, authentication, metrics/observability rigs, or integration with durable databases and migration histories.
