TARGET ROLES

Trading Operations Engineer Crypto PnL Reconciliation Bot Monitoring & Risk Ops

QA Automation Engineer Python Data Pipeline Specialist AI / Workflow Automation

PROFESSIONAL SUMMARY

QA and Python Automation Specialist with 5+ years in fintech, enterprise, and crypto operations. Expertise spans manual QA,
REST API validation, SQL-based data analysis, and end-to-end automation scripting. Currently focused on trading operations
automation: Hummingbot/Binance workflow automation, PnL reconciliation, config-level performance analytics, inventory risk
control, and decision-pipeline engineering. Proven ability to turn operational chaos into reliable, auditable systems — exactly the
discipline that separates profitable algo-trading from expensive guesswork.

PORTFOLIO PROJECT — CRYPTO OS

Crypto OS — Production analytics, risk-control and PnL reporting layer for Hummingbot Pure Market Making on
Binance Spot (Python · SQLite · Docker · Git)
• Built a deterministic Python/SQLite toolkit that reconciles Binance account trades into an accounting database with realized PnL,
mark-to-market true PnL (live Binance price fetch), and unrealized inventory valuation — eliminating a critical stale-price bug that
overstated true PnL by $29 on a $700 book.
• Designed a config lifecycle (WATCH → CANDIDATE → REFERENCE_READY) and multi-signal decision engine (market regime +
session adjuster + execution quality + spread-edge monitor + health score), producing a single FINAL_DECISION with confidence %
per pipeline run.
• Implemented HODL benchmark: every config is evaluated against passive SOL holding — ensuring active market-making genuinely
adds value beyond simple long exposure.
• Built alpha attribution engine separating realized trading alpha from market-direction PnL, revealing that v69's apparent $29 true PnL
was 52% market exposure — a critical insight for config promotion.
• Engineered session-aware spread adjuster (ASIA / EUROPE / US / LATE sessions), detecting that US session (14–20 UTC)
generated 100% of BUY_DRIFT inventory accumulation.
• Established data-integrity guardrails: config resolver, fill-drought detection, runtime YAML vs DB alignment check, config snapshot
backfill, and daily SQLite backup pipeline.
• Full audit trail in SQLite: fills · config_tests · config_profit_registry · config_lifecycle · kill_switch_log · execution_quality_decisions ·
market_regime_decisions.
• Prometheus/Grafana monitoring layer and Telegram read-only alert channel in roadmap; tagged production release
profit-pipeline-v1 on GitHub.

KEY ACHIEVEMENTS

• Fixed a $29 stale-price bug in mark-to-market PnL calculation — restored true_pnl from +$29.77 to real +$0.49, enabling correct
capital-scaling decisions.
• Designed a multi-signal decision engine (15 scripts, 12 SQLite tables) producing a single auditable trading decision per pipeline run.
• Separated realized trading alpha from market-direction PnL — revealed that 52% of v69 true PnL was inventory appreciation, not
active edge.
• Reduced regression testing effort by ~30% using Python automation scripts (Intellias).
• Accelerated Treasury document processing by ~40% through automated submission workflow (Military Administration).
• Built HODL benchmark and HODL-vs-PMM comparison — first honest measure of whether market making adds value.

Education Languages

Finance — Lviv Polytechnic National University, 2000–2008 Ukrainian — Native
