Work experience

Senior Python Developer

from 11.2020 to now (6 years)

Domain: Backend infrastructure for multi-platform trading operations, automated
Context: deposit/withdrawal orchestration, payment gateway integrations, and back-office
management systems for compliance and transaction oversight.

Key Achievements & Impact:
• Database & Infrastructure Optimization: Optimized heavy database transactions and refactored critical
service layers, dropping peak RDS CPU utilization from 95% down to under 80% and drastically reducing
HTTP 504 gateway timeouts under high load.
• Event-Driven Messaging & Integrations: Implemented event-driven consumers using RabbitMQ
exchanges to ingest real-time market trading events and configured Kafka subscribers for system
notification pipelines.
• Automated Profiling & Diagnostic Pipelines: Built a targeted incident capture system using py-spy ring
buffers triggered by Nginx latency watchers, automatically storing execution dumps and flame graphs upon
slow requests for rapid post-mortem analysis in test environments.
• AI-Driven Code Review & Quality Automation: Engineered custom, tiered AI code-review workflows
integrated into GitLab CI (offering light, standard, and detailed analysis modes), incorporating self-tuning
feedback loops that align AI suggestions with team standards while maintaining strict context budgets.
• Elasticsearch Upgrade & Migration: Executed a seamless data migration across 5 major Elasticsearch
versions (lacking native direct migration support), maintaining full data continuity and zero service
degradation during switchover.
• System Reliability: Led major dependency upgrades across core services without downtime, ensuring
stable middle-layer operations for high-volume financial trading platforms.
