SEPT 2024 — PRESENT

I’ve been working as part of a small Python integration team responsible for
integrating TheViewPoint and Tatari platforms to optimize ad monetization. The main
Hobbies objective of our team is to ensure seamless communication and reliable data exchange
I enjoy going to the gym, and about between the two systems.
six months ago I started taking
Our work typically starts with investigating how specific parts of Tatari operate
singing lessons, which I find very and determining whether it is possible to provide the required data. Based on
engaging and rewarding this research, the TVP team defines integration tasks for us, which usually involve
developing API endpoints or generating data files stored in Amazon Bitbucket.
Before implementation, we discuss the proposed solutions with Tatari engineers, then
implement the features, go through their review process, and deploy the changes to
production.

When there are no active integration tasks between TVP and Tatari, we support
Tatari’s MediaOps team by extending and fixing their internal admin panel. This
work includes improving Prelogs and Postlogs parsers, implementing conditional
email notifications for clients, resolving performance issues on reporting pages,
and handling various other backend tasks. This contribution is important for daily
operations, and our work is appreciated by internal stakeholders.

Tech stack: Python, Flask, SQLAlchemy, PostgreSQL

Python/Java backend developer, Faifly
MAR 2022 — AUG 2024

RPM365 is an American healthcare company that provides a range of medical
services, including doctor consultations and the manufacturing and sale of
medical devices. I was part of a 16-member team that utilized Scrum
methodology to enhance collaboration and efficiency. My role primarily involved
backend development—initially using Python/Django and later Java/Spring—where
I contributed to the discussion, development, testing, and documentation of new
features. I frequently focused on optimizing legacy code, particularly rewriting
database queries to improve performance.

Stack: Python, Django, Django Channels, DRF (Django Rest Framework), Celery,
Redis, MySQL.

Python backend developer, Faifly
JUN 2021 — MAR 2022

We developed an API for a card game available on mobile and web platforms for
clients in Kuwait (koutbo4, koutbo6, duwaween). Originally crafted by Faifly using
Python 2, our objective was to transition the project to Python 3, update the libraries,
and introduce new features. Our development team comprised one senior developer
and two junior developers, including myself. My primary responsibilities involved
upgrading the REST API from Python 2 to Python 3 using Django Rest Framework.
Additionally, I designed and implemented a new admin panel with Wagtail, enhancing
the system with CRM capabilities. I also integrated user registration features via
Facebook and Google.

Stack: Python, Django, Django Rest Framework (DRF), Wagtail, Celery, Redis,
MySQL

Full-stack developer, My own project
SEPT 2022 — APR 2024

In September 2022, I began developing my project, Chatty. It's a SAAS application.
The app allowed you to install a chat widget on your website for live interaction with
your visitors or to set up a chatbot that handles common inquiries automatically, all
designed through a user-friendly graphical interface. The technology stack includes
a backend composed of DRF, Celery, Django Channels, Wagtail, PostgreSQL, and
Redis, paired with a frontend built on Ts/Vue.js. The project employs GitLab CI/CD
for automated backend testing with every code push and is manually deployed using
Docker Compose (I haven't used Kubernetes or similar tools).

The backend repository is public and available for review, as the project is no longer in
active development: https://gitlab.com/den_zharikov/chatty_backend
