Full development cycle of AI web interface for education.

Led a team of 5 (DevOps, backend, frontend).

Architecture design, backend (Django, PostgreSQL), frontend.

AI API integration, WebSockets.

CI/CD setup, Docker containerization.

Admin panel for managing prompts and user scenarios.

Implemented webhooks for Telegram subscription management.

PostgreSQL-based subscription logic with HMAC-SHA256 validation.

Team leadership: Led a 7‑member engineering team; ran planning/standups/retros; delegated work; mentored developers; unblocked delivery.

CI/CD enablement: Helped design and configure CI/CD pipelines to automate build, test, and deployment; added checks to improve reliability and speed of releases.

Frontend development: Built features for a React SPA using Redux for state management and React Router for navigation.

API integration: Implemented client-side modules for API communication (request/response handling, authentication, error handling, and retries) and integrated them with Redux flows.

Code quality: Reviewed code across the frontend (React) and backend (Python FastAPI), ensuring consistency, performance, and adherence to project standards.

Frontend: React, Redux, React Router

API: Custom JS modules for REST (auth, retries, error handling)

Backend (in reviews): Python, FastAPI

CI/CD: Pipeline automation (YAML-based; e.g., GitHub Actions/GitLab CI)

VCS/Collaboration: Git, PR workflows and code reviews

Developed custom Go exporter for VPN API & PostgreSQL.

REST API for aggregated metrics → Prometheus.

Grafana dashboards for visualization.

Refactored 20k LOC monolith into modular async aiogram architecture.

Improved maintainability & async performance.

Retry logic for external APIs.

Dockerized deployment with configs via .env (Pydantic Settings).

Designed FastAPI-based payment microservice.
