I'm Zia, a full-stack developer specializing in React, Next.js, Node.js, and Microsoft Office & Google Workspace add-ins. I build production-ready tools that automate the software your team already uses.
Services
From production web apps to custom Microsoft and Google add-ins — here's where I help.
React, Next.js, and Node.js apps with REST/GraphQL APIs and databases (Postgres, MongoDB, SQL Server) — built to run in production.
Outlook, Word, Excel, and PowerPoint add-ins with Office.js, plus Microsoft Graph and Entra ID SSO — a niche most developers don't offer.
Sheets, Docs, and Gmail add-ons and automation with Apps Script — deployed to your domain or the Google Workspace Marketplace.
Generate documents, automate workflows, and add AI (Claude/OpenAI, RAG) inside the tools your team already uses.
Projects
A mix of production web apps and custom add-ins. Detailed case studies land here as I publish demos.
Businesses outgrow spreadsheets long before they can justify a bespoke internal tool. This is a multi-tenant SaaS dashboard with secure login, role-based access, full CRUD, and subscription billing wired to Stripe, JazzCash, and EasyPaisa. It's proof I ship real products with real payments — not just marketing sites.
Sales and support reps burn hours rewriting similar replies and copy-pasting threads into their CRM. This Outlook add-in drafts context-aware replies with AI and logs messages and contacts straight to the CRM through Microsoft Graph — without leaving the inbox. Follow-ups go out faster and nothing slips through the cracks.
Teams that crank out contracts, proposals, and letters retype the same boilerplate and end up with inconsistent documents. This Word add-in fills templates with structured data in a mail-merge style, generating on-brand documents from a single guided form. Manual assembly becomes a repeatable, error-resistant flow.
Analysts paste stale exports into Excel and rebuild the same calculations by hand. This add-in ships custom worksheet functions and syncs live data from an external API, refreshing cells as the source changes via worksheet events. Spreadsheets stay current with no manual re-imports.
Process
Whether it's a web app or an Office add-in, I plan the data, integrations, permissions, and deployment before building — so delivery stays predictable.
Clarify scope, data model, APIs, permissions, and where the manual work hurts — for web apps and add-ins alike.
Develop the React/Next.js UI, Node APIs, or Office.js / Apps Script add-in with clean, typed, maintainable code.
Ship to your host, AppSource, or the Google Workspace Marketplace — tested, documented, and handed off.
