I'm a Senior Integration Engineer with 6+ years of experience building scalable backend systems and API integrations using C#, .NET Core, and Azure. I specialize in healthcare interoperability (HL7, FHIR, HIPAA-compliant systems) with a track record of 99% integration success rates on production systems.
I also work with a small team of developers skilled in MERN/Next.js and Flutter, so I can take on full-stack and cross-platform projects beyond my core specialty when needed.
Send your requirements and I'll get back with an accurate scope and timeline.

FAQ
Do I need to provide API documentation before ordering?
Yes, please share the API documentation link (or any available reference) before placing an order so I can accurately scope the work and give you a precise quote and timeline.
What if the API I need doesn't have public documentation?
No problem — I can work with private/internal docs, Postman collections, or even reverse-engineer integration requirements from sample requests/responses if needed.
Do you have experience with healthcare/EHR API compliance (HIPAA, HL7, FHIR)?
Yes, I've integrated numerous healthcare APIs (Epic, Athena Health, Allscripts, and more) and understand HL7/FHIR data standards and healthcare data handling requirements.
How long does an API integration typically take?
It depends on complexity — simple integrations can take 2–3 days, while full custom API development with database integration may take 7–10 days. I'll confirm exact timelines after reviewing your requirements.
Will I receive the source code?
Source code is included in the Standard and Premium packages. The Basic package covers debugging/fixing without full source delivery — let me know if you need it added.
Do you offer post-delivery support if issues come up?
Yes, I offer revisions as included in your package, and I'm available for follow-up support or bug fixes after delivery.
Can you work with my existing codebase/tech stack?
Yes, I primarily work in C#, .NET, .NET Core, and Azure, and I can integrate APIs into most existing .NET-based systems.
