JAVLON BAXTIYOROV

Senior engineer on the internal platform Citifuel runs its daily operations on.

Stack: FastAPI, React, PostgreSQL, Redis, Celery, Docker

• Built one ERP dashboard that brings all six departments into a single system (billing, verification, customer support, pre-qualifier, collections, and deal closing), each with its own automations and reports, and access limited to the right people.
• Built the CMP Connector, a gateway that gives every internal project one safe, rate-limited way into CMP (the core ERP), instead of each project logging in on its own and risking the shared account getting blocked.
• Worked on payments, authentication, and session security across these systems.
• Pulled reusable parts out into open-source libraries: fastapi-passkeys, fastapi-trusted-devices, and unipay-uz.

Led backend engineering for a high-traffic, AI-powered education ecosystem (soff.uz, soffia.uz, soffcrm.uz), and mentored the team while doing it.

Stack: Django, FastAPI, PostgreSQL, Redis, Celery, Docker, AI integrations

• Designed the backend and APIs with Django, FastAPI, Redis, and PostgreSQL for a high-load platform where traffic ran well above the active-user count, around 2.5 million.
• Built AI-powered automation and educational content-generation services (presentations, papers, tests), including STT/TTS and NLP pipelines.
• Mentored and managed two junior developers — owning their growth, code quality, and day-to-day delivery.
• Optimised backend infrastructure for high-load and real-time services.

Backend systems in Python and Django, with AI models integrated into production products (the TANA healthcare platform).

Stack: Django, DRF, FastAPI, PostgreSQL, Redis, WebSockets, Docker

• Built a FastAPI WebSocket microservice for real-time patient queue management (TANA Health), decoupled from the Django monolith.
• Integrated AI/NLP models for automatic tagging and smarter search (TANA Clinics).
• Collaborated with cross-functional and AI/ML teams to ship high-quality software.

Backend solutions in Python and Django with a focus on performance.

Stack: Python, Django, Docker, Redis, Celery

• Implemented APIs and integrated third-party services.
• Used Docker, Redis, and Celery to improve system performance.

Backend services across a range of client projects — real estate, automotive, hospitality — most shipped end to end.

Stack: Python, Django, DRF, PostgreSQL, Docker, Nginx

• Developed and optimised backend services; tuned PostgreSQL performance.
• Shipped real-world products: Evolution Motors, Leapmotor CA, HighTownCity.uz, Hologorod.
• Version control with Git; containerisation with Docker.

First production ground — learned that shipping is a discipline, not an event.

Stack: Python, Django

• Designed and developed backend solutions for client projects.
• Integrated external APIs and collaborated closely with frontend developers.

Open-source libraries used in production and by other engineers.

• fastapi-passkeys — storage-agnostic WebAuthn / passkey authentication for FastAPI.
• fastapi-trusted-devices — device trust & session-security primitives for FastAPI.
• unipay-uz — unified payment-gateway integration for Uzbek providers.

One dashboard for the whole company, so no department needs a separate tool.

Stack: FastAPI, React, PostgreSQL, Redis, Celery

• Six departments in one place: billing, verification, customer support, pre-qualifier, collections, and deal closing, each with its own data, automations, and reports.
• Access is scoped by department (people see only their own; admins see everything), with passwordless login through a Telegram bot.
• Celery background jobs handle payment reminders, Zoho Desk ticket sync, a timezone-aware calling cadence for leads, and bulk collections reports.

A gateway between Citifuel's internal projects and CMP, the core ERP.

Stack: FastAPI, Redis, httpx, Docker

• The problem: every project logged into CMP with the same account and made its own uncoordinated requests, which looked like abuse and could get the account blocked.
• The fix: one service logs in once, shares and auto-refreshes the token, and projects call the connector with an API key instead of CMP credentials.
• Added global rate-limiting so calls to CMP are spaced out, plus Redis caching of common responses to cut repeated load.

AI-powered educational ecosystem serving thousands of users, consisting of multiple interconnected services.

Stack: Django, FastAPI, PostgreSQL, Redis, Docker, AI integrations

• soff.uz — Main digital marketplace for ready-made academic materials, 3D designs, website templates, and freelance services. Hosts 1.5M+ academic works and 2K+ templates.
• soffia.uz — AI academic assistant that generates presentations, course papers, reports, tests, and research documents in seconds. Serves 20K+ users with Google and Telegram auth.
• soffcrm.uz — Internal CRM for users, seller accounts, sales pipelines, and platform analytics.

Healthcare management system combining a Django monolith with a FastAPI microservice for real-time queue management via WebSockets.

Stack: Django, DRF, FastAPI, PostgreSQL, Redis, WebSockets, Docker, Nginx

• Designed and implemented a FastAPI microservice for real-time patient queue management using WebSockets.
• Integrated the microservice with the Django monolith to synchronize patient and appointment data.
• Improved scalability by decoupling real-time features from the core monolith.

Stack: Django, PostgreSQL, Python 3, AI models (NLP, ML), Nginx, Gunicorn

• Implemented AI models for automatic tag generation from service descriptions.
• Integrated AI into the search functionality to improve service discovery.

Real estate platform for sale and rental of luxury apartments and commercial spaces in the High Town residential complex.

Stack: Django, PostgreSQL, Python 3, Jinja2, Nginx, Gunicorn

• Developed the real estate management system and all website pages.
• Integrated the application form with AMOCRM for automated client request management.

Courses: Python Programming Basics, Advanced Python, Database Management, API Development, Backend Projects.

• Authored technical articles on Python and Django — Telegram blog with 500+ monthly readers (t.me/DevFlowJavlon).
• Conducted online workshops for junior developers on backend development best practices.
