Synergy University Moscow: Management of Information Systems (2017)Python Backend Development
Extensive expertise in Python backend development using FastAPI, Pydantic v2, SQLAlchemy, Alembic, Celery, Flask and Django. Design and implementation of REST and OpenAPI services, webhooks and queue-based architectures with RabbitMQ and Redis.
Cloud and Platform Engineering (AWS, Kubernetes)
Deep hands-on experience with AWS services including ECS Fargate, Lambda, Step Functions, API Gateway, S3, DynamoDB, CloudFormation and Cognito, as well as GCP. Kubernetes cluster management with RKE2, EKS, Helm, Rancher and Docker, combined with infrastructure-as-code using Pulumi, Terraform, Terragrunt and Ansible.
ML and AI Platform Engineering
Practical experience building and operating ML and generative AI platforms using MLflow, FreqAI, Optuna, CatBoost, scikit-learn, FAISS, sentence-transformers and OpenAI SDK. Integration of LangChain, Claude Code, Codex, Cursor and MCP servers for AI-driven development workflows and agent-based automation.
DevOps and CI/CD
Proven track record in delivery and security automation using GitHub Actions, GitLab CI/CD and Jenkins. Tooling includes pytest, mypy, Ruff, Vault, least-privilege IAM, Bandit, CodeQL, Dependabot and Wiz, with CVE response at fleet scale.
Data Engineering and Databases
Broad experience with relational and NoSQL databases including PostgreSQL, MySQL, MongoDB, ClickHouse, Redis, DynamoDB and ArcticDB. Covers migrations, backups and restore testing.
Observability and Monitoring
Setup and operation of observability stacks using Prometheus, Grafana, Alertmanager, Thanos, CloudWatch, Sentry and Langfuse for production systems.
Blockchain Infrastructure
Operation of blockchain data platforms indexing multiple EVM networks in real time. Management of full nodes, real-time block indexers, tx-details and tracer services across bare-metal and Kubernetes clusters.
Frontend and Mobile Development
Frontend and mobile development skills covering React, TypeScript, Vite, Next.js on the web side, and Swift with SwiftUI as well as Kotlin with Jetpack Compose for native mobile applications.
Fraud Detection and Fintech Systems
Design and delivery of real-time fraud detection systems using ETL on Airflow, feature engineering, CatBoost training, real-time scoring, MLflow model lifecycle, monitoring and alerts. Saved a payment processor client 500,000 EUR per year.

Project history
Cloud-native trading platform on AWS using Python, FastAPI, Freqtrade, MLflow, Pulumi, ECS, Lambda and DynamoDB. Built an AI-driven SDLC on Claude Code with coordinator and parallel worker agents, designed trading-safety controls, led least-privilege IAM hardening and implemented fail-closed infrastructure deployment guards.
Operated a blockchain data platform indexing 6 EVM networks in real time across ~70 bare-metal/VPS hosts and three Kubernetes clusters. Managed full nodes, real-time block indexers, day-to-day operations of 70+ hosts, built AI-assisted documentation and runbooks, automated TLS certificate issuance and led security patching campaigns.
Client project that checks a bank-transfer receipt in a fraction of a second and returns accept, review or reject with a 0-100 risk score and an explanation. Built with FastAPI, Pydantic, PostgreSQL 16, RabbitMQ, Redis, OpenAPI with API keys, idempotency keys and signed webhooks, and a React and TypeScript interface with role-based access.
