About this gig
Whether you need to build an API or plug into someone else's, I'll make the two systems talk.
I've built and consumed plenty of APIs over 16+ years, so I handle auth, rate limits, and the edge cases that quietly break integrations later.
What I can do: build REST endpoints for your app or site, connect you to a payment, shipping, CRM, or any external API, set up webhooks and background jobs, and hand over clear docs so the next developer isn't lost. I work mainly in PHP, Python, and Node, whatever fits your stack.
If it has an API, I can almost certainly connect to it. Send me its docs and I'll confirm. I handle the security side too: API keys, OAuth, tokens, and rate limits.
Tell me what needs to connect to what, and I'll map it out and give you a clear quote before you order.

I'm Gunjan (GJ), a full-stack developer with 16 years building for the web. I work in WordPress, WooCommerce and Shopify, and a lot of my work now is AI: chatbots trained on your content, AI agents, and automations that remove repetitive tasks. Expect clean, update-safe code, fast sites that work on mobile, and fixes that don't break other things. Whether you need a custom plugin, a Shopify store, a site rescued from errors, or AI built into what you already have, tell me what you're trying to do and I'll give you the honest, simplest way to get there.
