What I do

Expertise

How I turn unclear product needs into maintainable backend systems, stable frontend interfaces, reliable integrations, and delivery workflows that can be operated by real teams.

Backend & Platform Architecture

I design backend systems with clear boundaries between transport, application logic, domain rules, persistence, and infrastructure. Preferred stack: FastAPI, SQLAlchemy 2.0, PostgreSQL, Alembic, Redis, RBAC, OAuth2/JWT, domain events, and Outbox patterns.

Frontend Product Engineering

I build practical frontend applications with React, TypeScript, and Next.js, focusing on dashboards, admin panels, maintainable components, SSR/SSG, and interfaces that support real business workflows.

Marketplace & Commerce Systems

I work with commerce workflows, marketplace integrations, product/order data, operational dashboards, seller processes, Ozon, Wildberries, Yandex Market, 1C, CRM systems, stock analytics, adverts, supplies, and reporting.

Integrations & Workflow Automation

I connect external APIs, internal systems, ETL pipelines, scheduled jobs, Airflow-backed workflows, imports/exports, payment APIs, and Telegram bots to reduce manual work and improve operational reliability.

Cloud, DevOps & Delivery

I use Docker, docker-compose, GitLab CI/CD, GCP Cloud Run, Cloud SQL, Artifact Registry, OpenTofu direction, and infrastructure scripting to ship repeatable deployment workflows.

AI-Assisted Engineering

I use ChatGPT, Claude, Copilot, and PyCharm AI/code generation to accelerate planning, implementation, testing, refactoring, and review while keeping architecture decisions and final responsibility human-led.
