I built a Google Apps Script that connects HubSpot to Google Sheets and pulls CRM data automatically. It authenticates with a HubSpot API token, fetches contacts and deals (including custom properties), and writes them into separate, auto-created Sheets tabs—making it easy to build dashboards and reports without manual CSV exports.

I built a Google Apps Script that connects LinkedIn Ads to Google Sheets using the LinkedIn Ads API. It handles OAuth with refresh and access tokens, pulls ad performance metrics like reach, impressions, clicks, CTR, and spend, and writes the results into a clean, automated spreadsheet for ongoing LinkedIn Ads reporting.

I built a Google Apps Script that pulls Klaviyo campaign performance into Google Sheets for automated reporting. It authenticates with a private API key, fetches campaign metadata and delivery metrics with pagination, merges everything by campaign ID, and writes a clean, refreshable table to Sheets—ideal for comparing campaigns and building custom Klaviyo dashboards without extra tools.

I built a Google Apps Script that connects the Apify API to Google Sheets and runs any Apify actor—like a Yellow Pages scraper—directly from a spreadsheet. It triggers the actor, fetches all dataset items (name, URL, address, phone, rating, images, categories), and bulk-writes the results into a clean Sheet, giving you a fast, reusable workflow for loading Apify data without tools like Zapier or Make.

I built a Google Apps Script that connects the Discord API to Google Sheets by routing requests through a Cloudflare Worker proxy. It uses a Discord bot token and channel ID to fetch messages, then bulk-writes them into a clean Sheet for logging, reporting, and automation—ideal for bringing Discord server activity directly into spreadsheets.

I built a Google Apps Script that connects WooCommerce to Google Sheets using the WooCommerce REST API. It authenticates with your store’s API keys, fetches all orders with pagination, maps key fields like status, dates, and totals, and writes everything into a clean Sheet—perfect for automating order exports and simple WooCommerce reporting.

It's been great working with Nicolas. He was very quick at understanding what I was trying to build and he built it within the timeline provided and at the cost we agreed on. Probably the best part is how easy it is to get in touch with him and agree on changes to be made as the product is developed. Highly recommend him.

We hired Nicolas to optimize and add automation to several of our Google Sheets, and he exceeded expectations. He quickly understood the scope of our needs, offered smart workflow improvements, and implemented clean, effective automation that saved us hours of manual work. Communication was clear and timely throughout the project, and he was flexible with revisions. Highly recommend for any Google Sheets or automation tasks!

Chrome extension with API integration and workflow automation

It's been a great experience working with Oscar all the way through. He's been very precise from the very beginning with regards to pricing, timelines and the ease of communication was the best I've experienced. He was always available to talk on short notice regarding the changes to the project. He is very knowledgeable in APIs and backend but most importantly he was very helpful in building a streamlined architecture.
