Microsoft Office Add-in Developer for Outlook and Word
Nadeem Ashfaq did an outstanding job developing custom add-ins for Outlook and Word. Office add-in development can be notoriously tricky with manifest configurations and cross-client compatibility (web vs. desktop), but he handled it effortlessly. He delivered clean, well-documented code, integrated our required APIs seamlessly and communicated clearly throughout the process. Highly recommend Nadeem for any Office.js or Microsoft ecosystem development.

From Vibe Code to Production
With the rise of AI tools like Cursor, Claude, and Lovable, building a proof of concept has become faster than ever. But AI-generated applications often hit a wall when moving into production: weak architecture, security gaps, poor maintainability, and scaling limitations.
I specialize in auditing, refactoring, and stabilizing AI-generated applications — transforming prototypes into secure, production-ready systems built for long-term growth.
Over 10 years, I have designed and delivered enterprise software across Microsoft 365 and modern web platforms, including Office Add-ins, SharePoint integrations, Microsoft Graph solutions, and secure cloud-based architectures — implementing tenant-wide SSO using Azure AD (Entra ID) and modernizing legacy VSTO solutions into Office.js and modern web applications.
What separates my work
Before building or refactoring, I evaluate platform constraints, API limitations, deployment requirements, and architectural tradeoffs.
If a proposed implementation conflicts with Office.js capabilities, SharePoint constraints, authentication boundaries, or enterprise deployment realities — I identify it early and provide practical alternatives.
You get clear technical guidance before development starts, not expensive rewrites later.
Core Expertise
Microsoft 365, SharePoint & Enterprise Solutions
— SharePoint Online customization and solution architecture
— SPFx web parts and extensions using React & TypeScript
— Document libraries, lists, permissions, metadata, and governance
— SharePoint + Microsoft Graph + OneDrive integration
— Intranet portals and enterprise collaboration solutions
— Modernization and migration strategies across Microsoft ecosystems
Office Add-ins & Office.js
— Word, Excel, Outlook, and PowerPoint Add-ins
— Task panes, shared runtime, and event-driven architectures
— Custom Excel Functions and real-time integrations
— Enterprise deployment and centralized manifest management
— Azure AD (Entra ID) authentication and SSO
— Migration from VSTO to modern Office.js applications
AI Refactoring & Full-Stack Architecture
— Architecture audits and production hardening for AI-generated software
— Node.js, Python, REST APIs, and GraphQL services
— OAuth2, OpenID Connect, JWT, RBAC, and secure identity flows
— React, Next.js, TypeScript, and scalable frontend architecture
— PostgreSQL, MongoDB, MySQL, schema optimization, and performance tuning
How I Work
I design before I build.
Every engagement starts with an architectural assessment. I identify security boundaries, scalability bottlenecks, operational risks, and maintainability concerns before development begins.
You receive production-grade code, transparent communication, strong documentation, and predictable delivery.
If you need to modernize a SharePoint environment, stabilize an AI-generated application, or build a complex Microsoft 365 solution from day one — let's talk.
