Flagship Architecture•Full Stack Developer
Live Platform

Alpha CRM Platform

Modern CRM platform engineered for sales intelligence, automated lead pipelines, and AI-assisted workflows with end-to-end type safety.

Problem Solved

Replaced fragmented spreadsheet workflows with an automated multi-tenant pipeline processing high-velocity sales pipelines in real time.

Architectural Decisions

Implemented an end-to-end type-safe client-server contract using Next.js App Router and tRPC, partitioned MySQL schemas for tenant isolation, and designed optimistic UI state hydration.

Technical Highlights

  • ›End-to-end type-safe contract with Next.js App Router, tRPC, and Zod
  • ›Multi-tenant MySQL schema partitioning with role-based access control (RBAC)
  • ›Sub-100ms pipeline Kanban and real-time lead distribution engines
  • ›Optimistic cache mutations and instant UI responses via TanStack Query

SSR Data Table

ReactNuqsShadcn UITanStack TableTypeScript

High-performance data table component with server-side pagination, multi-column sorting, and URL-synchronized state via Nuqs and TanStack Table.

Problem Solved

Eliminated client-side memory overhead and desynchronized filter states when rendering complex tabular datasets.

  • ›Bi-directional URL search params synchronization with zero layout shift
  • ›Server-driven multi-column sorting, faceted filters, and cursor pagination
  • ›Accessible Shadcn UI primitives with full keyboard navigation
