Custom Web Systems
APIs, integrations and backend built to measure for your business needs
I build backend systems and APIs that solve your business's specific problems, with clean architecture, tests from the first commit, and infrastructure that handles growth.
What I deliver
- REST APIs with automatic documentation (OpenAPI/Swagger)
- Integrations with legacy systems (SOAP, REST, webhooks)
- Secure authentication (OAuth2, JWT, sessions)
- Background processing with queues (Celery, RabbitMQ, Kafka)
- Architecture that separates business logic from infrastructure
- Automated tests and CI/CD configured
- Technical documentation for your team to maintain without me
