▸ Led SharePoint SPFx development — delivered 7 enterprise SPFx (React) applications across multiple enterprise clients, covering Invoice Management, Delegation Systems, Promo Portal, and Task Tracker. ▸ Solved a critical 200,000-item single-list migration (on-premises to SharePoint Online): diagnosed threshold failures with PnP/REST, then re-architected using Microsoft Graph API with indexed columns and server-side pagination — eliminating all load failures and enabling smooth production rollout. ▸ Architected reusable SPFx component library and cross-application delegation pattern adopted across all 7 apps, reducing new-module scaffolding time significantly. ▸ Built backend for Loci Marketplace (location-based e-commerce platform) using ASP.NET Core — integrating Google/Apple OAuth, Square Payments, Google Maps geo-search, and real-time SignalR chat with buyer/seller/admin financial settlement modules. ▸ Resolved Loci API performance bottleneck using optimized stored procedures, reducing endpoint response time from 3–4 seconds to milliseconds in production.

Architected Minimal APIs on ASP.NET Core with PostgreSQL, designing a shared backend architecture serving both a Blazor web app and mobile client from a single centralized codebase — eliminating duplicate logic across platforms. ▸ Implemented MSAL/OAuth role-based access control across 3 user types (Candidate, Admin, Job Poster), ensuring each persona only accesses permitted modules and operations on both web and mobile surfaces. ▸ Delivered backend modules end-to-end within a 4–5 person dev team, tracked via YouTrack with Git/Azure DevOps for version control — reporting architecture decisions directly to the CTO.
