API Development & System Integration

$65/hr Starting at $1K

I design and develop secure, scalable API infrastructures and backend systems tailored to your business goals. With over 20 years of experience in enterprise software development and cybersecurity, I help startups, SaaS platforms, and enterprises build modular, maintainable, and fully documented API ecosystems that can scale with their user base and integrate across services.

Whether you're building a new product, refactoring legacy code, or need to integrate with Stripe, Salesforce, or a custom frontend — I bring proven expertise in Python (FastAPI), secure authentication (OAuth2, JWT, MFA), API architecture, and deployment pipelines.

My solutions are compliance-ready (HIPAA, GDPR, OWASP), developer-friendly, and built with real-world usage in mind.

What I Offer:

  • RESTful API Development (FastAPI / Flask)

  • JWT / OAuth2 Authentication, TOTP MFA

  • PostgreSQL, Redis, and advanced DB integration

  • Stripe, Salesforce, Twilio, and 3rd-party API integration

  • Role-based Access Control (RBAC)

  • Swagger / OpenAPI Docs & Postman Collections

  • Secure CI/CD Deployment (Docker + GitHub Actions)

  • Logging, rate-limiting, audit trails


 Ideal For:

  • SaaS Platforms & Startups

  • Healthcare, Finance, Legal Tech

  • Enterprise Internal Tools

  • CRM & ERP Backend Developers

  • AI & Data Platforms that need secure APIs
