About Ruslan
ERPNext / Odoo Developer | Python | Django | React | Integrations
Dnipro, Ukraine - 1:12 am local time
I build and customize business software: new ERP functionality, work inside existing codebases, and connections between ERP systems and external services or mobile apps.
ERPNext / Frappe and Odoo
- ERPNext / Frappe customization and development
- Custom apps, DocTypes, modules and business logic
- Python server-side development
- Reports, workflows, scripts and automation
- ERP integrations with external systems and APIs
- REST APIs and webhooks
- Odoo customization and integration
- ERP deployment and maintenance
I have developed and customized ERPNext for a manufacturing business, covering warehouse, accounting, production and HR functionality, along with custom Python / Frappe applications and frontend work.
Backend and full stack development
- Python / Django
- Node.js
- React / Next.js / Vite
- REST APIs
- PostgreSQL / MySQL
- Docker / Linux VPS
- Third-party API integrations
- Webhooks and automation
I can build a complete application: backend, API and frontend. I can also join an existing project and take responsibility for specific features, integrations, fixes or ongoing development.
ERP and mobile applications
I develop mobile applications and connect them to ERP systems and business workflows.
- React Native applications
- Native Android development with Kotlin
- Native iOS development with Swift
- Mobile apps connected to ERPNext / Odoo through APIs
- Custom mobile applications for warehouse, sales, field service and other ERP workflows
A mobile app extends the ERP past the desktop: inventory management, order processing, warehouse operations, field work, sales and internal workflows.
VoIP and call center solutions
I deploy and configure self-hosted VoIP and call center systems based on Asterisk and Wazo.
- SIP configuration
- Extensions and call routing
- IVR systems
- Call queues
- Business telephony workflows
- Integration with ERP, CRM, web applications and other business software
E-commerce and OpenCart
I write commercial extensions for OpenCart across different versions, including modules distributed through specialized e-commerce marketplaces. The work covers custom, third-party integrations, modifications to existing stores, custom themes, performance optimization, and both backend and frontend development.
Integrations and AI
I connect business systems to external services using APIs, webhooks and custom backend logic. I also build AI-powered features and AI automation that plug into existing processes.
Recent work
ERPNext for a manufacturing company:
- Deployed ERPNext on a Linux VPS using Docker
- Customized warehouse, accounting, production and HR functionality
- Developed custom Python / Frappe applications
- Worked on React / Vite frontend components
- Integrated business processes and custom functionality into the ERP
I take on short tasks as well as long-term projects. That can mean fixing one specific issue, building an integration, or developing and maintaining a full business
If you need a developer who understands the business logic behind an ERP and the technical side of it, backend, frontend, integrations and mobile, send me the details of your project.
