FAQs

Do you build APIs from scratch too?
Absolutely. I can design and develop secure REST/GraphQL APIs tailored to your project.
Will the integration be secure?
Yes I follow best practices with authentication, token management, and data validation.
Can you help if my current API integration is buggy?
Definitely I can debug, fix, and optimize existing integrations.
What’s the usual timeline?
Simple integrations: 1–2 days. Custom APIs: 1–3 weeks depending on scope.

I enjoyed working with Marc. He's an easy going guy that actually knows his stuff. I was a bit worried when we hit some snafus, but he got the job done. Note: Allow more time than you think because we hit delays with Replit and Supabase

Professional negotiations and high quality project management and work product. Was very flexible to adjust deliverables when asked on many of the different projects I’ve outsourced to Marc.
