I am a Senior Software Developer with 5+ years of experience building custom Microsoft Office Add-ins for Outlook, Word, Excel, PowerPoint, Project, and enterprise solutions using Office.js and VSTO (.NET/C#). I have delivered secure, scalable, cross-platform add-ins across Windows, macOS, Office Online, and mobile, focusing on clean architecture, performance, and professional workflows. I have developed Outlook Add-ins for email automation, reusable templates, smart auto-replies (OpenAI/ChatGPT), meetings & calendar tools, CRM/ERP sync, background tracking, and Microsoft Graph & Exchange API integrations, including mail-merge with live data. In Excel, I implemented live API data sync, Custom Functions, Excel-DNA/VSTO automation, bulk data processing, dashboards & charts, Power BI & SQL integrations, and AI-driven insights for enterprise reporting. For Word, I built one-click document generation, content controls, clause/template libraries, API-driven reports, and AI-assisted writing tools. In PowerPoint, I delivered automated slide creation, branded layouts, slide libraries, real-time data injection, chart automation, and AI slide summaries. I have also developed Project Add-ins for task automation, project data sync, reporting dashboards, and enterprise workflow extensions. Beyond Microsoft Office, I have created Google Workspace Add-ons for Gmail, Docs, Sheets, and Calendar, implementing automation, API integrations, and AI-powered workflows. Additionally, I have experience in cross-platform desktop apps (.NET, WPF, WinForms, Electron), backend platforms (.NET Core, Node.js, Python), REST/GraphQL APIs, Microsoft Graph, SharePoint, OneDrive, and Google APIs. I ensure enterprise-grade security, OAuth2, SSO, Microsoft Identity, CI/CD, Azure DevOps, GitHub Actions, and AppSource deployment. I deliver business-ready add-in solutions that optimize processes, enhance productivity, and meet enterprise standards.
