Jaques.
AI Integration Engineer based in Lisbon. I connect LLMs to real business systems: API integrations, RAG pipelines, and workflow automation.
Lisbon · 2026An engineer
who runs ops.
Six years at a SaaS startup taught me that shipping is just the beginning. What compounds is the system around it.
I'm an AI Integration Engineer based in Lisbon with an unusual combination: a continuous six-year journey at ChatGuru, growing from first Customer Success hire to Director, plus IntegraNinja, a part-time integration consultancy I founded and ran alongside it, delivering automation for clients in legal, retail, healthcare, and real estate.
My work sits where LLMs meet real business systems: API integrations, RAG pipelines, multi-agent workflows, and the operational backbones I spent years optimizing by hand. Currently studying AI & Machine Learning Engineering, focused on building scalable, useful systems.

How I solve
real problems.
Semantic search over support tickets
An IT services client had years of resolutions locked inside Freshservice tickets. Agents kept solving the same issues from scratch.
RAG pipeline with Freshservice, Supabase pgvector, and n8n sync workflows. Embeddings on ticket resolutions, retrieval wired into the agent workflow.
Past resolutions surfaced instantly during triage, as part of an automation program that cut manual effort by 60%.
AI on the WhatsApp API: JIPPfy
Small businesses answering the same WhatsApp questions by hand, all day, every day.
Next.js product on the WhatsApp API with LLM-driven agent workflows (GPT and Claude APIs) handling first-line conversations.
Automated first-line replies in production. Live at jippfy.pt.
CRM / ERP integration delivery
Client data siloed across HubSpot, Pipedrive, Salesforce, SAP, and custom APIs, with teams re-typing data between systems.
n8n and Make workflows, REST APIs and webhooks, plus Python microservices, owning the full lifecycle from requirements to delivery.
15+ client projects delivered across legal, retail, healthcare, real estate, and professional services, cutting manual work by 60%.
