B2B SaaS products whose enterprise sales deals depend on native integrations with GitHub Apps, GitLab, Jira, Linear, Notion, Confluence, Google Drive, and Box frequently search to hire a freelance SaaS integration ecosystem programmer. I am Aldian Fazrihady, a Senior Freelance Full Stack Developer and AI Integration Architect.

Core B2B Integration Marketplace & Connector Capabilities

  • GitHub Apps, GitLab & Linear Engineering Connectors: Building webhook-driven PR review bots, automated issue-to-commit linking, CI status checks (`check_runs`), and codebase RAG indexers using fine-grained GitHub App installation tokens.
  • Notion, Confluence, Google Drive & SharePoint Knowledge Connectors: Synchronizing hierarchical pages, permissions, and attachments incrementally via delta cursors into your multi-tenant `pgvector` RAG store.
  • Unified OAuth Token Vault & Sync Health Monitoring: Managing encrypted OAuth2 token refresh cycles, rate-limit backoff queues, and customer-facing connection health indicators.

Frequently Asked Questions

Should we use an embedded iPaaS (Paragon / Nango / Merge) or build native connectors for our top 5 integrations?

Using Nango or custom OAuth workers for your core 5 integrations avoids $30k+/year iPaaS enterprise contracts while giving you full control over delta-sync latency, webhook reliability, and custom data transformations.

How do I hire you to build our native SaaS integrations?

Hire me via Upwork.
