AI & Intelligent Automation

  • Build integrations for AI-powered features like workflow automation, smart agents, and data enrichment modules.
  • Contribute to the development of agent-based microservices and LLM-enhanced features using Python libraries and APIs.
  • Collaborate with the product team to bring AI-driven experiences into the product roadmap.

System Integration & Business Logic

  • Manage multi-system orchestration including syncing accounting records, CRM triggers, and automated payments.
  • Ensure fault-tolerant logic with retries, exponential backoff, and graceful degradation for all external API interactions.

Required Skills & Experience

  • Proven track record of building enterprise-grade APIs and integrations with platforms like Wafeq, QuickBooks, Xero, Zoho, and CRMs.
  • Deep understanding of software architecture, design patterns, and clean code practices.
  • Strong expertise in MySQL, including query optimization, indexing, and data migrations.
  • Hands-on experience with AWS (EC2, S3, RDS, CloudWatch, IAM) for cloud-native deployments.
  • Experience with GitHub Actions and CI/CD pipeline automation.
  • Solid experience integrating and managing payment gateways such as Stripe, Paymob, etc.
