Key Projects CRM System for Electricity Consumption Data Collection and Analysis (Django) One of the key projects was the development of a CRM system for collecting and analyzing electricity consumption data using Django. I built a web application with a monolithic architecture that enables management companies and resource supply organizations to efficiently collect, process, and analyze electricity consumption data. Thanks to Django's built-in ORM tools, middleware, and Redis caching, the system reliably handled up to 100 concurrent users. Authentication based on Django Auth and a notification system via Django Signals alerted consumers about meter reading deadlines and outstanding payments. The project ran on Nginx. CRM System for a Freight Transportation Company (FastAPI) Developed a CRM system for the dispatch service of a freight transportation company, built on a microservice architecture using FastAPI. The system automated the creation of orders, driver assignment, shipment status tracking, and trip cost calculation. Landing Pages (Flask) Beyond CRM systems, I developed over 20 landing pages using Flask for small businesses — including a dental clinic, fitness club, law firm, and delivery restaurant.
