You will get API Integration | REST API | Webhook Setup | Third Party App Connection
Project details
Two tools that will not talk to each other cost you a person. Somebody sits there copying an order from one screen into another, and getting it wrong occasionally.
I connect them properly.
Most integrations work fine on the happy path and fall apart the first time the other service is slow, returns an error, or sends the same webhook twice. So that is what I build for. Retries with backoff. Idempotency, so a duplicate event never creates a duplicate record. A queue, so nothing is lost when the other end is down. And an alert to you when something genuinely needs a human.
What you get:
• The integration, live and working
• Retries, backoff and duplicate protection
• Monitoring, with alerts on failure
• The code and the field mapping, documented
Starter is one direction. Standard keeps both systems in sync. Advanced connects several systems with queueing and monitoring.
Tell me which two tools and I will tell you honestly whether their APIs allow what you want.

About Guglielmo
AI Agents, Chatbots & Workflow Automation | Production AI Engineer
Milan, Italy - 7:36 pm local time
I build AI agents, chatbots and automations that run in production: connected to your real data, wired into the tools your team already uses, and still standing after the first thousand messages.
WHAT I BUILD
• AI agents that actually do the work. Multi-step reasoning, tool calling, and the guardrails that stop them going off-script or running up your bill.
• Chatbots that answer from your own documents, with the source attached to every answer and an honest "I don't know" instead of an invented one.
• Workflow automation, n8n or custom, that removes the task nobody on your team wants to do twice.
• AI built into the app you already have, rather than a separate toy nobody opens.
WHY CLIENTS KEEP COMMISSIONING
I ship on rails. A written plan before I touch code. Staging before production. Numbers you can verify instead of adjectives. I name my own bugs before you find them, and I will tell you when a feature is not worth building, which costs me money and saves you more.
My last client commissioned continuously for five months and wrote this: "one of the most substantive technical collaborations of my career."
HOW I WORK
Fully asynchronous, entirely in writing. No calls, no standups, no scheduling across time zones. You get updates you can read at 2am and forward to your team, and every decision stays on the record instead of evaporating in a meeting.
Stack: Python, FastAPI, Next.js, PostgreSQL, pgvector, Docker, OpenAI and Anthropic APIs, Stripe. MIT Professional Education certificate in Large Language Models. Background in security, which mostly shows up as systems that fail closed instead of loudly.
Tell me the outcome you need and what is currently in the way. You get back a scoped plan with a fixed price, usually same day.

Assume the other side will break
I map the fields both ways, then build with retries, backoff and idempotency so a duplicate webhook does not create a duplicate record. Then I test what happens when the other service is down.
