Ukraine-based developer, available remotely, CET-friendly hours. Long-term contracts and short freelance tasks both welcome. The project history below shows the kind of systems I build. Tell me what you need — I'll say straight away if I'm the right fit.

I develop and maintain business software end to end: ERP systems, backend services, web and mobile applications, integrations and production deployment.
My strongest area is ERP development and business process automation. Most of that work has been for manufacturing, warehouse, finance, sales and logistics.
ERPNext / Frappe
My largest ongoing project is an ERPNext system for a perfume manufacturer, built from scratch. I set up the infrastructure and architecture, then developed custom functionality for production, warehouse, inventory, sales, purchasing, accounting and HR. I have been the main developer and technical point of contact for that system since day one.
I write custom Frappe applications instead of modifying the ERPNext core:
- Custom DocTypes and business logic
- Workflow automation, Server and Client Scripts
- Scheduled jobs and background processes
- Reports, dashboards and print formats
- Role-based permissions
- Data migration from legacy systems
- REST API integrations
- ERPNext upgrades and custom app maintenance
One of those apps is a scanner-driven warehouse system tied into ERPNext: barcode scanning, electronic scales, thermal printing, stocktaking and dispatch.
Odoo
I develop and customise Odoo modules and business workflows, including QWeb reports, automated actions and third-party integrations.
I have worked with Odoo 16, 17, 18 and 19, on both Community and Enterprise. I also migrate and port custom modules between major versions after upgrades.
Python backend and integrations
I build backend systems and integrations with Python, Django, FastAPI and Flask. Typical work:
- REST APIs and backend architecture
- PostgreSQL, MySQL and MariaDB
- Authentication and permissions
- Background and scheduled tasks
- Celery and Redis
- Docker deployments
- Third-party API integrations
- Webhooks and automated data synchronisation
I connect ERP, CRM, e-commerce, payment and logistics systems into automated workflows with validation, retry logic and failure handling.
Mobile applications
I build mobile applications for business and ERP systems on Android and iOS.
For example, a Kotlin Android app for warehouse TSD devices, integrated directly with ERPNext for warehouse operations and barcode workflows. I also use React Native for cross-platform apps and Swift for native iOS.
Web and e-commerce
I use React and Vue for web applications and internal business interfaces.
Infrastructure and delivery
Linux · Nginx · Docker · Git · VPS/Cloud · SSL · CI/CD
I can own the whole technical lifecycle: architecture, development, integration, deployment and production support.
You get the full source code, and I write it to be extended later rather than rewritten.

Project history
Built and maintain the complete ERPNext infrastructure for a perfume manufacturing company — from an empty server to a production system covering the full operational cycle.
• Server setup and deployment: Linux, Nginx, SSL, backups, staging environment
• System architecture: chart of accounts, item and warehouse structure, roles and permissions
• Manufacturing: BOMs, work orders, production planning, raw material consumption tracking
• Inventory: multi-warehouse stock, batch tracking, stock reconciliation and reporting
• Sales and purchasing workflows, approval logic, custom print formats and documents
• Custom Frappe applications: custom DocTypes, Server and Client Scripts, scheduled jobs, workflow automation, Script Reports and dashboards
• REST API integrations with external services
• Data migration from the previous system
• Version upgrades of ERPNext and all custom applications
• User training and ongoing production support
I am the sole technical point of contact for this system: I handle architecture decisions, development, deployment and support, and work directly with department heads to translate business processes into system logic.
Stack: ERPNext, Frappe Framework, Python, MariaDB, Vue, Kotlin, JavaScript, Linux, Nginx
Independent contract work for multiple clients in parallel with my main long-term project — ERP customisation, backend development and system integrations across different industries and company sizes.
• ERPNext / Frappe: custom applications and DocTypes, workflow automation, Server and Client Scripts, Script Reports and dashboards, custom print formats, role-based permissions
• Odoo: custom modules, business logic, QWeb reports, automated actions
• ERP installation and deployment on client servers, staging setups, version upgrades of ERPNext and custom modules
• Data migration into ERP from spreadsheets and legacy systems
• REST API integrations between ERP, e-commerce, payment and logistics systems, including webhook handling, scheduled synchronisation and retry logic
• Python backend development with Django, FastAPI and Flask
• Troubleshooting and rescuing broken customisations, including systems where previous developers had modified core files
Typical engagements range from short scoped tasks to multi-week module development. On most of them I work directly with the business owner or operations manager, scoping the work myself and delivering documented, maintainable code.
