About this gig
Do you need to connect your Java application to an external service
or API? GitHub, Slack, payment gateways, or any custom REST API
this is exactly what I do professionally.
At eQ Technologic I spent 3.7 years building full connector systems

enterprise analytics platform from scratch. I've handled SAML auth
flows, chunked pagination pipelines, dynamic model creation, and
delivered a 70% performance improvement in production.

Any REST API into your existing Java/Spring Boot application
Authentication handling (API keys, OAuth, SAML, Basic Auth)
Error handling, retries, timeouts, and edge cases
Pagination and data transformation
Kafka event-driven integration pipelines
Database integration (SQL, Neo4j)
Clean, documented, production-ready code
Why choose me:
⭐ 3.7 years professional Java integration experience

FAQ
Which APIs have you integrated professionally?
I've professionally integrated Sonatype Nexus REST API, Bitbucket API (Data Center and Cloud), ThingWorx, and Neo4j. Personally I've also built a GitHub REST API integration with Kafka event processing. I can work with any well-documented REST API.
What do you need from me to get started?
I need your API documentation or Swagger specs, the base URL and auth method (API key, OAuth, SAML etc), and what data you want to send or receive. Message me before ordering and we'll align on scope and timeline.
Can you work with my existing Java codebase?
Yes — I'm experienced integrating APIs into existing Spring Boot applications without breaking existing functionality. Share your codebase structure and I'll confirm fit before you order.
