I will build API integrations, webhooks, and custom middleware
Ayoub ETOULLALI
Level 1
About this gig
Broken integrations, failed webhooks, and manual data re-entry drain operational revenue and create sync errors.
I engineer enterprise-grade middleware and API integrations that keep your systems synchronized in real time with zero data loss.
What you get:
Resilient System Sync: Connect ERP, CRM, Shopify, and PIM platforms via REST or GraphQL.
Fault-Tolerant Pipelines: Idempotent data flows, retry queues, and automated error recovery.
Webhook & Auth Security: Enforce OAuth2, HMAC validation, and sensitive data protection.
Production Monitoring: Detailed logging, alerting triggers, and performance runbooks.
Why work with me:
Big Data and Cloud Engineer with 50+ deployed production systems. I build scalable middleware focused on uptime, data integrity, and enterprise security.
Pricing & Scope Transparency:
The Basic tier covers single endpoint diagnostics, webhook debugging, or technical consults. Complete custom middleware builds and bi-directional sync pipelines are scoped via custom offers.
Message me with your API docs to get a clear technical roadmap today.

FAQ
Why is there a price difference between the Basic tier and custom builds?
The Basic tier covers single-endpoint diagnostics, bug repairs, or technical consults. Complete multi-system middleware with bi-directional syncing, queuing, and security requires dedicated custom architecture scoped via a tailored offer.
How do you protect API keys, sensitive credentials, and client data?
I adhere to strict security protocols. All secrets and API credentials are kept in secure environment variables, data in transit is encrypted, and PII is scrubbed from logs. I am happy to sign a Non-Disclosure Agreement (NDA).
What deliverables and post-delivery support do you provide?
You receive fully commented, tested source code, deployment scripts, Postman collections, and documentation. I also include post-delivery monitoring support to verify zero data loss during live traffic.
What technical details are needed to get started?
Please share your target systems, API documentation or Swagger URLs, sandbox credentials, and an explanation of the expected data flow, triggers, and payload mapping.
