Ahmad R.

API Integration Specialist | HIPAA | HL7 | FHIR

I build API integrations that don't break in production — webhooks, retries, idempotency, audit logs — on WordPress and PHP. One ad-tech client hired me three separate times and now runs a $15K+ ongoing contract for Snapchat & TikTok ad-API automation (450+ hours, every contract closed at 5.0 — "Ahmad is incredible, would highly recommend for any project"). Recent proof: - Two-way Twilio SMS/MMS WordPress plugin shipped for a US insurance brokerage — CSV upload, MMS, two-way inbox, message templates. Live in production 4+ years. - Snapchat & TikTok ad-API automation for a US ad-tech firm — thousands of events/day, webhook → CRM → ERP sync, built to debug at 2am. - Insurance lead-exchange integration — SFTP sync + Klaviyo automation, end to end. What I do best: - API integrations: Twilio, Stripe, Klaviyo, Airtable, Meta/TikTok/Snapchat ad APIs, OpenAI/Anthropic — with retries, queueing, idempotency and the observability to catch failures before your client does. - Custom WordPress plugins & REST endpoints — ACF Pro, custom post types, admin dashboards. No Elementor bloat unless you ask for it. - WooCommerce customization and lead-pipeline back-ends that sync cleanly at scale. Stack: WordPress, PHP, JavaScript/TypeScript, MySQL, REST APIs, Twilio, Stripe, Klaviyo, ACF Pro, Gravity Forms, WooCommerce, Vue.js, Node.js, Git, webhooks. Top Rated Plus. 100% Job Success. Replies in under 4 hours. Send me the brief. I'll send back a 1-page scoped plan — phased, with acceptance criteria and a fixed-vs-hourly recommendation — the same day.
