Diego C.

I design and deploy automation and data systems that make business processes faster, more reliable and measurable — and I prove it with numbers. RESULTS FROM REAL PROJECTS • Cut materials planning from 40 min to 50 sec per batch using AI-assisted structured queries. • Reduced route planning for a 12–15 technician field team (~120 jobs/day) from 30 min to 3–4 min per city. • Replaced a fully manual document process with an automatic commercial-sheet generator (multi-schema SQL → JSON → FastAPI/Python → 100+ Power Automate and n8n flows). • Built an AI multi-agent assistant (Copilot Studio) that answers questions over files and PostgreSQL data in natural language, respecting Microsoft 365 permissions. • Delivered Power BI dashboards with automated KPI alerts (email/Teams), used monthly by management, plus automated Microsoft 365 permission audits via Graph API + Python. • Cleaned and standardized a legacy ERP customer database (addresses in 4 languages) with SQL. WHAT I BUILD • Automation: n8n, Make, Power Automate, Zapier, UiPath, GoHighLevel, REST APIs, webhooks • AI & agents: agent, skill and plugin creation; API usage with vision and function calling; RAG pipelines (vector databases, embeddings, chunking); LangChain; OpenAI Assistants API; Azure AI; Claude & Claude Code; Copilot Studio; MCP • Data & BI: Power BI (DAX, Power Query M, custom HTML graphics), SQL/PostgreSQL, Python ETL, Looker Studio, Google Cloud, Excel • Microsoft ecosystem: Power Platform, Copilot Studio, Azure Cloud, Outlook, Teams, Business Central, SharePoint (SPFx), Graph API, AppSheet — I also deploy solutions natively inside these apps. HOW I WORK Spec first, then build. I document the architecture, deliver reusable systems (not one-off hacks) and keep you updated regularly. Industrial engineer by training: I find the root cause before automating anything.
