Summary
Python backend developer building asynchronous REST APIs with FastAPI (asyncio) and DRF on PostgreSQL, Redis and Celery,
tested and deployed via GitHub Actions CI/CD. Currently building payment and platform integrations for an EdTech company’s CRM.

Experience
CRM Developer (part-time) — Turbo Education Oct 2026 – Present
Stack: Zoho CRM, Deluge, Zoho API, n8n (webhooks), WayForPay, sandbox testing
– Built automated monthly payment plans (invoice series with due dates, amount reconciliation, duplicate protection) and a
WayForPay integration: payment links, payment verification and auto-closing of invoices.
– Rebuilt access sync CRM → n8n → LMS via webhooks (access rules, DRY RUN mode, retries, access revoke); automated support-
manager assignment with loop-free two-way sync.
– Found legacy-sync defects; planned a rollback strategy and a staged 6-wave production rollout.

Team Project
Mental Health Platform — Backend Developer (team of 11) § Sep 2026 – Present
Stack: FastAPI, async SQLAlchemy 2.0, PostgreSQL, Alembic, Redis, Groq API, Stripe, WayForPay, Docker Compose, GitHub Actions
– Main backend contributor (∼75% of backend code) of a platform where an AI assistant matches clients with psychologists.
– Built a separate AI chat microservice from scratch: streams LLM replies via Server-Sent Events, keeps dialogue history in Redis,
behind an interface that allows swapping Groq, Gemini and Grok clients.
– Implemented psychologist matching: ranking by symptom overlap with filters by gender, price, language and time slots.
– Designed the PostgreSQL data model and Alembic migrations; implemented Google OAuth login, JWT in HttpOnly cookies and
refresh-token rotation with reuse detection.
– Designed a provider-neutral payment interface (factory, Stripe and WayForPay providers, normalized webhooks); fully async services
with blocking SDK calls moved to asyncio.to thread.

Projects
Online Cinema API — capstone project § Jul 2026 – Sep 2026
Stack: FastAPI, async SQLAlchemy 2.0, PostgreSQL, Alembic, Celery, Redis, Stripe, MinIO, Nginx, Docker, Pytest, AWS EC2
– Developed a backend for an online movie store: 70+ endpoints for accounts, profiles, catalog, cart, orders and payments, fully
asynchronous (async SQLAlchemy, asyncpg, aioboto3, aiosmtplib), layered routes / services / models.
– JWT auth with email activation, RBAC, Celery periodic tasks, MinIO (S3) storage; Stripe Checkout with idempotent web-
hooks and refunds.
– Wrote 286 integration and E2E tests (Pytest, HTTPX, fakes behind ABC interfaces); CI/CD in GitHub Actions with auto-deploy
to AWS EC2 behind Nginx.
Airport API Service — DRF, PostgreSQL, Docker § Jun 2026 – Jul 2026
– REST API for flights, routes, crews and ticket orders with JWT auth; optimized queries with select related / prefetch related,
added filtering, throttling, Swagger docs and 64 API tests, with CI deploy to Render.
IT Company Task Manager — Django, PostgreSQL, Bootstrap § Dec 2025 – Mar 2026
– Project, team and task management app with auth, search and pagination; 250+ unit tests, CI and auto-deploy to Render.
