About this gig

I build APIs other developers can actually work with, and connect systems that were never designed to talk to each other.


10 years of enterprise integration - banking platforms, healthcare systems, IoT device data, BI tools and compliance software. I've connected Jira to a GRC platform, IoT devices to a national health system, and Salesforce to an agentic AI layer.


WHAT I BUILD

- REST and GraphQL APIs, versioned and documented

- Third-party integrations: payment, CRM, ERP, messaging, analytics

- Webhook handling with retries and idempotency

- Authentication: OAuth2, JWT, API keys, role-based access

- Rate limiting, caching and pagination that scales

- OpenAPI and Swagger documentation your team will actually use


INTEGRATION IS MOSTLY EDGE CASES

The happy path takes a day. What takes skill is the timeout, the duplicate webhook, the partial failure and the schema change. I build for those from the start.


STACK

Java, Spring Boot, Node.js, Python, FastAPI, Django, REST, GraphQL, OAuth2, Postgres, MySQL, MongoDB, Redis, Kafka, Docker, AWS, Azure, GCP
