About this gig

Tired of broken syncs, missing orders, and it worked yesterday automations?


Get a reliable API integration that connects your app to the services you depend onso data flows automatically and errors are traceable. Perfect if you need REST API connections, a Custom API layer, or event-driven webhooks for real-time updates.


What this gig can deliver:


REST API integration (auth/OAuth, pagination, rate limits, retries)

Build or extend a Custom API (clean endpoints for your application)

Shopify API integration (orders, customers, products, inventory)

eBay API integration (listings, orders, tracking/status sync)

Webhooks setup + debugging (signature validation, dedup/idempotency, logging)

Testing & verification (Postman) + clear handover notes/API documentation



Outcomes you can expect: fewer manual steps, faster updates, fewer failed requests, and a maintainable integration your team can extend.



To start, send your API docs/keys (sandbox is fine), the workflow (trigger action), sample payloads, and your stack/hosting.

Hi, I'm Ifeoluwa Titilayo, an App, API & Web Developer who builds clean web apps and reliable back-end services. I design and consume RESTful APIs, create custom endpoints, integrate third-party platforms, and implement secure webhooks for realtime updates (orders, users, payments). I troubleshoot failing calls, fix broken automations, improve performance, and document clearly so your product is easy to maintain and scale. I work with JavaScript/TypeScript, Node.js, React, databases (SQL/NoSQL), OAuth/JWT security, testing, and smooth deployments, so features ship fast and stay stable.
