AI systems don't stay fixed forever. APIs update. Models behave differently. Edge cases surface after launch. Business requirements change.
I provide ongoing technical support and maintenance for AI systems that were either built by me or by another developer keeping your chatbots, automation workflows, data pipelines, and AI applications running reliably.
What I handle:
Bug fixes and breakage caused by API changes (OpenAI, Anthropic, Zapier, n8n, Make)
Prompt tuning to improve AI response quality over time
Performance optimization (reduce latency, cut costs, improve accuracy)
New feature additions to existing systems
Platform migrations (e.g., moving from Zapier to n8n, or GPT-3.5 to GPT-4o)
Security reviews and data handling audits
Response quality monitoring and improvement
I take over existing AI systems built by others regularly. Just give me access to the codebase or platform account and a description of what's broken or what you want improved I'll diagnose and fix without unnecessary rebuilding.
The monthly retainer model is ideal for businesses that have live AI systems serving real customers and can't afford downtime.

Are you losing hours every week to repetitive tasks that a well-built automation could handle in seconds?
As a Fiverr Vetted Pro with deep expertise in AI-powered workflow automation, I design and build production-grade systems using n8n, Make (formerly Integromat), and Zapier the three leading platforms for connecting your tools, AI models, and data sources into seamless automated pipelines.
What I build:
Lead capture and CRM enrichment pipelines
AI-powered email triage and response workflows
Multi-platform data sync (Airtable, Notion, Google Sheets, HubSpot, Salesforce)
Automated reporting and notification systems
OpenAI / Claude / Gemini integrations into your existing workflows
Webhook-based event triggers and real-time data processing
My builds include built-in error handling, retry logic, and execution logging so your automation doesn't silently fail at 2am. Every workflow comes with clear documentation so your team can understand and maintain it.
I work with businesses across SaaS, real estate, e-commerce, health services, and agencies. Whether you need a single zap or an interconnected system of 10+ workflows, I scope clearly, build cleanly, and deliver on time.
