We set up a program that visits the websites you care about and copies the information you need, like prices, listings or reviews, into your spreadsheet on a schedule. **Problem:** Copying data by hand does not scale, and off-the-shelf scrapers break the moment a site changes its layout or blocks automated traffic. You need data you can rely on every day, not a script that works once. **What you get:** - Custom scraping solutions for static, dynamic and login-required websites - Real-time or scheduled data extraction (hourly, daily or weekly) - Anti-bot handling: rotating proxies, headless browsers, retries and CAPTCHA handling where lawful - Data cleaning, deduplication and formatting - Delivery to CSV, Excel, Google Sheets, JSON, PostgreSQL, MongoDB or an API - Full source code, documentation and monitoring **Stack:** Python, Playwright, Selenium, Scrapy, BeautifulSoup, Crawlee, PostgreSQL ### [Workflow automation](https://bigibyte.com/services/workflow-automation) Reports and updates that run themselves. We connect the tools you already use so repeated jobs, like weekly reports, copying data between apps or sending alerts, happen on their own. **Problem:** Your team spends hours every week moving data between email, spreadsheets, CRMs and chat. Every manual step adds delay and mistakes. **What you get:** - Workflow design mapped to your real process - n8n, Make or Python automations with error handling and retries - Connections to Gmail, Google Sheets, HubSpot, Slack, Airtable, Notion, webhooks and APIs - Scheduled runs, triggers and alerts - Logging so you can see what ran and when - Setup notes and a walkthrough for your team **Stack:** n8n, Make, Zapier, Python, Webhooks, Google Apps Script ### [Apify actors](https://bigibyte.com/services/apify-actors) We build, publish and maintain it. We build a ready-to-run data tool, publish it on the Apify Store where other people can use or buy it, and keep it working. **Problem:** Your scraper lives on someone's laptop, nobody monitors it, and results never reach the tools your team uses. **What you get:** - Custom Apify actor for your target site (static, JavaScript or login pages) - Input schema, README and a sample dataset - Pagination, proxy setup and retry logic - Deployed in your Apify account: you own the actor and code - Delivery to JSON, CSV, Excel, Google Sheets, Airtable or webhooks - Optional Apify Store publishing and maintenance **Stack:** Apify, Crawlee, Playwright, Puppeteer, Node.js, Python ### [Data pipelines](https://bigibyte.com/services/data-pipelines) Deduplicated, normalized, loaded. We gather data from all your sheets, tools and sources every day, remove duplicates, tidy it up and put one clean version where your team works. **Problem:** Data arrives from many sources in different shapes, with duplicates and gaps. Reports break and nobody trusts the numbers. **What you get:** - Pipeline design from source to destination - Cleaning, normalisation and deduplication - Validation checks and anomaly alerts - Loading into PostgreSQL, BigQuery, Snowflake or Sheets - Scheduling, logging and monitoring - Documentation of every field **Stack:** Python, pandas, dbt, Airflow, PostgreSQL, BigQuery ### [Web Automation & Browser Bots](https://bigibyte.com/services/web-automation) Logins, forms and downloads. We build a small bot that logs in to websites, fills in forms, downloads files and clicks through the same steps a person would, on a schedule. **Problem:** Some tasks only exist inside a web interface: daily logins, report downloads, form submissions. Doing them by hand wastes hours and invites mistakes. **What you get:** - Browser automation for any web app - Form filling, uploads and submissions - Scheduled logins and report downloads - Data entry automation - Testing automation for your own apps - Desktop apps for Windows, Mac or Linux that run with one click **Stack:** Python, Playwright, Selenium, Puppeteer, PyQt ### [Google Sheets automation](https://bigibyte.com/services/google-sheets-automation) Less copying, fewer mistakes. We add automations to your Google Sheets so they pull in new data, format it, send emails and build summaries without anyone copying rows. **Problem:** You are copying rows by hand, fixing broken formulas and waiting on slow sheet workflows that only one person understands. **What you get:** - Custom Apps Script automations - Formulas for lookups, reports and clean data flows - Triggers for forms, schedules and email alerts - Menus or buttons so your team can run jobs without code - API, webhook and web scraping feeds into your sheet - Export automation to Excel, CSV or PDF **Stack:** Google Sheets, Apps Script, Google Forms, Gmail, Drive, APIs ### [Python scripts & bots](https://bigibyte.com/services/python-scripts-bots) One click instead of an hour. We write a small program for a task you repeat, like merging files or sending messages, so it takes one click instead of an hour. **Problem:** You have a repetitive task that no off-the-shelf tool handles quite right, and doing it by hand is slow. **What you get:** - Custom Python scripts to your specification - Desktop tools with a simple GUI (Tkinter or PyQt) - Telegram, Discord and Shopify bots - Excel, file and image automation - API integrations - Clean, documented source code **Stack:** Python, pandas, Tkinter, PyQt, Selenium, Requests ### [AI-powered scraping bots](https://bigibyte.com/services/ai-scraping-bots) AI reads each page for you.
