Project details
Tired of wasting hours on manual processes or disconnected systems? Get a custom API designed specifically for your business workflows. Your API will be fast, secure, and fully documented - ready to use immediately.
Every API includes:
• Fast setup (your API running in days, not weeks)
• A database-backed API with full documentation
• Dockerized app so it works right out of the box
When you’re ready to grow, easily add authentication, AWS deployment, or third-party integrations like Stripe, Twilio, or GoHighLevel. I'm available for support after the initial project and can easily extend the API to make your workflow as seamless as possible.

Job Success
Eugene, United States - 4:28 pm local time
During my time on Upwork, I've architected high-performance APIs, HIPAA-compliant systems, and worked with clients across healthcare, law, and government domains. I've listed a few examples below, and my project history has more, with client reviews for reference.
Few examples:
- Built high volume APIs handling 10M+ requests per month, allowing client data that was previously entered manually to flow directly into the right CRM workflows at scale. The system is built to be modular and work with a variety of vendors, which allowed the company to rapidly scale its acquisition of new clients, and process their data efficiently.
- Developed a lead processing system, integrated with Retell AI, that allows for automated qualification of leads, follow up workflows depending on the lead status, and an always on presence that has led to a 10% increase in booking conversions.
- Designed HIPAA aware backend systems for healthcare workflows involving sensitive data, access controls, auditability, and operational reliability. I have experience with EHRs, such as NextGen and Epic.
- Implemented a GIS API and backend platform for a government client, working from provided specifications to deliver spatial data integration, secure access patterns, and multi-environment deployment workflows.
If you need to automate workflows, connect systems, or build a scalable backend or AI integration, send me a message with what you are working on. I am happy to take a look, talk through the workflow, and let you know where I can help.

Requirements Review
I’ll review the endpoints, data fields, and database needs you’ve provided to get a better idea of how you would like the API to function, and ask any questions that require clarification, and provide advice as needed.
API Development
I’ll build the requested endpoints, integrate the database, and ensure each endpoint returns proper structured responses according to your needs.
