Web Application Development

Full-stack: Python and Javascript

Full-stack development

Work both with frontend and backend — from an idea to a ready service.

Modern stack

Use Django and Nuxt.js/Vue.js for speed, security, and scalability.

Post-launch support

Support projects, adding new features and fixing bugs.

Custom solutions

Each project is tailored to the business needs, not to a template.

Services

Web Application Development

I create powerful and user-friendly web applications using Django, Nuxt.js, and Vue.js. I design architecture, ensure security, and work with databases (PostgreSQL, MySQL) and APIs.

API and Backend Service Development

I develop REST APIs using Django and FastAPI. I optimize queries, ensure data protection, and integrate with payment systems, external services, and mobile applications.

Telegram Web Apps Development

I develop mini-applications inside Telegram using Vue.js and Nuxt.js. I create custom interfaces, interact with Telegram API, implement authentication and payments, and ensure high security.

Project Refinement and Optimization

I fix bugs, optimize performance, and improve codebase and interfaces. I help develop projects by adding new features, improving architecture, and integrating with other services.

CRM System Development

I create custom CRMs on Django and integrate them with other services and systems. I set up client management, deal tracking, automated reporting, and integration with payment systems and APIs.

Custom Projects on Demand

I develop unique projects tailored to client business logic. These can include dashboards, marketplaces, analytics systems, booking platforms, chat systems, and more.

Business Process Automation and Integration

I help automate company workflows: API integration, automated data processing, report generation, process monitoring, and Docker container setup for better manageability.
