Overview
A frontend-focused UI engineer at a junior level who delivers single-file, end-to-end client features. The strongest proven skill is client-side UI implementation with validated API interaction, exemplified by generatePaletteFromApi and displayPalette in unstonio/colorGPT/index.html. There is little evidence of component architecture, testing, advanced accessibility, or performance engineering in public code.

Overview
A pragmatic backend/API engineer at an experienced mid-to-senior level who builds small production systems end-to-end. The strongest proven skill is implementing REST services and payment/subscription flows with concrete idempotency and schema-evolution measures (see server/src/index.js and server/src/db.js). The public code lacks systematic testing, advanced distributed-systems patterns, and formal secrets/CI hardening documentation.

A backend-focused engineer at about a Senior level who authors production Python services and non-trivial domain logic. The strongest proven skill is building reliable document-consolidation backend logic and a file-backed registry - evidenced by contract_mvp/engine.py (consolidation algorithms) and contract_mvp/registry.py (transactional storage, revision management) with tests. Public code lacks evidence of multi-service distributed design, systematic migration history, or mature observability/ops integrations.

A pragmatic backend engineer at a middle level who builds end-to-end asynchronous Telegram bot features and payment integrations. The strongest proven skill is implementing payment-related flows and local persistence, supported by the SQLite manager (tgbot/sqlite/database.py) and scheduled payment-check logic (tgbot/apscheduler/check_bitcoin_payment.py). The work shows modular bot architecture and integrations but lacks migration histories, systematic retries/backoff, formal API contracts or observability/metrics instrumentation.

A seasoned engineering generalist focused on building robust local-first AI tooling and backend services at a senior level. The strongest proven skill is designing a production-focused persistent memory and search stack (SQLite + FTS5 + hybrid vector search) with idempotent migrations and comprehensive unit/integration tests - see mnemon-memory-mcp/src/db.ts and src/tools/memory-search.ts. There is limited public evidence of formal CI flakiness remediation, large-scale performance testing (load/soak), or an enterprise-grade flaky-test quarantine system.

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).

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.

Overview
Backend engineer (senior-level) focused on building LLM-backed retrieval and RAG pipelines for security workflows. The strongest proven skill is designing a hexagonal Python FastAPI service with adapters, reproducible offline eval and extensive integration tests (see app/api/app.py, app/adapters/* and app/eval/*). The public code shows limited evidence of large-scale multi-region distributed systems, long migration histories, or advanced SRE/runbook artifacts.

Overview
An iOS engineer at a solid middle level who delivers well-structured UIKit features with MVVM/presenter-interactor patterns and custom transitions. The strongest proven skill is building polished, interactive UI components and lists - evidenced by the compositional diffable collection layout (MyCode/HistoryScreen/UI/HistoryCollection/HistoryCollectionView.swift) and custom animated/interactive transitions (MyCode/HistoryScreen/PresentDismissTransition.swift). The portfolio lacks measurable performance profiling, a robust offline sync engine, extensive lifecycle-process-death handling and release/CI artifacts in public code.

Backend • Senior • 9+ years exp • Management: 1-2 years • 30 years • Moscow, Russia • Fully remote • Actively seeking • English: B1
Overview
A backend-focused engineer at a senior (lower-mid) level who consistently delivers well-structured prototypes and production-adjacent services across Node.js and Python stacks. The strongest proven skill is building robust API-backed tools with clear domain logic and test coverage - for example the bank-statement parsing + normalization pipeline (server/import/parseStatement.ts and server/import/normalize.ts) and the FastAPI LLM run/save/validate flow (backend/app/main.py + backend/app/models.py). Public code shows limited operational tooling and monitoring, and there is little evidence of multi-service production operations, advanced DB migration history, or formal secrets-management beyond environment variables.

AI/ML • Senior • 4+ years exp • Actively seeking
Overview
A competent ML engineer at a senior (applied) level who builds end-to-end model training, inference and MLOps pipelines. The strongest proven skill is building billing-aware training and inference pipelines with thorough validation and tests - exemplified by the training_feasibility logic and the extensive training/inference test suite. There is limited evidence of measured efficiency work, distributed training architecture, or original research contributions in public code.
