Salaj A
About this gig
Struggling with manual data entry, broken sheet formulas, or disconnected business tools?
I engineer production-grade Google Apps Script automations and custom Google Sheets web apps that turn tedious workflows into reliable, one-click engines.
Unlike basic coders whose scripts break when a column moves, I build modular, self-healing systems designed for enterprise stability.
️ What I Automate & Build: Sheets & Workspace Automation: One-click PDF generation (Docs/Slides/PDF), bulk Gmail dispatchers, automated triggers (OnEdit, OnChange, Cron). Third-Party API Integrations: Etsy Open API v3 (OAuth PKCE), Instagram Graph API, Razorpay, Stripe, Shiprocket & custom webhooks. Custom Web Apps (Sheets Backend): Full Single Page Applications (SPA), client/staff portals, OTP verification, and live KPI dashboards.
Real-World Experience: Built EdTech grading portals, automated Etsy catalog sync engines, and web scraping dashboards for international clients.
Please message me with your workflow details before ordering so we can confirm the best package!

FAQ
Do you need access to my Google Account?
No. You can invite me as an editor to a dedicated Google Sheet, or I can develop the script in a staging sheet and provide clear instructions / .clasp repository for seamless 1-click deployment into your workspace.
What happens if Google changes something or my sheet columns change?
I design all scripts using a centralized configuration file (GLOBAL_CONFIG) and self-healing schema validators. If columns are moved or renamed, the script adapts without crashing.
Can Google Sheets really work as a web app or database?
Yes! Using Google Apps Script's HTML Service, we can build responsive, fast Single Page Applications (SPAs) with modern interfaces, using Google Sheets as a free, reliable cloud database.
