I build production-ready web applications, Microsoft 365 solutions, and AI-powered software — from architecture through deployment and long-term maintenance. Businesses hire me when they need more than a working prototype: secure architecture, reliable integrations, maintainable code, and systems built to scale. With 6+ years of software development experience, including enterprise Entra ID SSO and VSTO-to-Office.js modernization, I focus on getting the architecture right before it ships. Full-Stack Development & AI Application Engineering - React, Next.js, TypeScript, Node.js, and Python - REST and GraphQL APIs, third-party integrations, and backend services - PostgreSQL, MongoDB, MySQL, and performance optimization - Authentication and security: OAuth 2.0, OpenID Connect, JWT, and RBAC - AI-powered applications and LLM integrations - Architecture reviews, debugging, refactoring, and production hardening - Fixing and stabilizing applications built with Cursor, Claude, Lovable, and similar AI coding tools Microsoft 365, SharePoint & Office Add-ins - SharePoint Online, SPFx, intranets, web parts, and document libraries - Word, Excel, Outlook, and PowerPoint Add-ins using Office.js - Microsoft Graph, OneDrive, and Entra ID SSO - Add-in deployment, manifest management, and VSTO-to-Office.js modernization - Power Apps and Power Automate solutions From Vibe Code to Production AI tools make prototypes faster to build, but production software requires sound architecture, secure authentication, robust error handling, proper data modeling, and maintainable code. I audit AI-generated applications, identify architectural and security weaknesses, fix integration issues, and help turn prototypes into reliable software that's ready to deploy and maintain. How I Work I assess before I build. I evaluate platform limitations, security boundaries, architecture, and deployment constraints upfront, so you get clear technical guidance before development starts — not expensive rewrites later. You can hire me to build a complete application, develop a Microsoft 365 solution, review your architecture, or fix and improve an existing codebase. Have a project in mind? Send me a short description of what you're building and the challenges you're facing. I'll help you identify the right approach, potential risks, and a practical path forward.
