Do you need a custom business tool, to modernize existing software, or to connect your systems together?
That's my job.
WHO I AM
Backend developer specializing in business applications for SMEs. I design ERPs, management tools, integration middlewares, and data pipelines that solve concrete operational problems.
My approach: understand your business before writing the first line of code. Then deliver a functional, tested, deployed, and documented product.
REFERENCE MISSION
E-commerce ↔ WMS integration middleware deployed in production:
→ Real-time bidirectional synchronization: orders, fulfillments, tracking
→ OAuth authentication, AES-256-GCM encryption, asynchronous architecture
→ Secure REST API: authentication, rate limiting, data validation
→ Deployed in production on a Linux server with monitoring
Result: complete elimination of manual data entry between systems, end-to-end traceability, zero human intervention on the order → shipping flow.
WHAT I DO
→ Custom business applications (ERP, WMS, CRM, management tools, portals)
→ Modernization of existing software (legacy, migration, architecture, CI/CD)
→ System integration (e-commerce ↔ ERP, CRM ↔ invoicing, supplier catalogs)
→ Process automation (data pipelines, reporting, dashboards)
HOW I WORK
1. I understand your business, your processes, and your constraints
2. I design the architecture and the data model
3. I develop and test (89% coverage on my pipelines)
4. I deploy in production with monitoring and documentation
5. I provide support after delivery
