I transform manual, fragmented workflows into reliable, automated systems.
Most businesses don't need complex new software. They need their existing data, tools, and AI to work together. I bridge the gap between "just a spreadsheet" and a fully functional internal tool that scales.
🚀 What I do for my clients:
Finance & Data Centralization: Turning multiple disconnected sheets, QuickBooks records, or files into a single, automated "source of truth."
AI & LLM Integrations: Connecting tools with AI APIs (OpenAI, Anthropic, Grok) to automate smart data extraction, categorization, or lead scoring.
Internal Web Apps: Creating easy-to-use interfaces (AppSheet) so non-technical teams can manage data without breaking the underlying logic.
Workflow Automation: Building bulletproof pipelines using n8n, Make, and Zapier so data flows seamlessly.
🛠️ Tech Stack:
Automation Engines: n8n, Make, Zapier.
Google Ecosystem: Apps Script, AppSheet, Advanced Sheets.
Custom Development: Python (Upwork Certified), REST APIs, Data Scraping, JSON/PDF parsing.
My goal is to make your operations invisible and error-proof, so you can focus on growing your business instead of managing files.
👉 Send me a message describing your current manual process, and I’ll design an automated solution for you.

With an extensive Upwork client history profile and having been Expert-vetted by Upwork as being in the top 1% of freelancers, I look forward to working with you soon! I am an integrations expert and am able to use tools such as Zapier, Microsoft Power Automate (formerly called Flow), and Make (formerly called Integromat), to create API integrations between many different applications. I have a keen understanding of backend data and how to easily get relevant information from one system to another. Integrating systems on the backend helps business workflow to be simplistic, efficient, and fast. I have been working on integrations since 2016, and have linked together numerous CRMs, accounting systems, marketing systems, spreadsheets, etc in a variety of ways, some simple and some extremely complex. Given API documentation, I am able to build custom connections, triggers, and actions in Zapier for many cloud based applications that do not yet have Zapier integration.
Some of my other skills include Javascript, Airtable, Google Sheets, Google Forms, Fillable PDFs, Softr, JotForm, Typeform, Fillout Forms, X2CRM, Excel, Canvas, Planning Center, TeamUnify, Amateur Radio Operator, French language.
As the owner of Glaive Consulting, I understand the needs of the small business owner to automate as much of the business as possible to allow focus on client work. Task tracking, time tracking and invoicing and customer followup are among some workflows that I have optimized for my business. Let me help you do the same!
