AI-Powered Application Solutions

Alameda County ITD modernizes aging legacy systems into fast, secure, cloud-ready web applications — built with the Claude Code AI development agent. Two applications are live in production and in daily use by the Public Works Agency (PWA).

The Alameda County Information Technology Department (ITD), in partnership with County agencies and departments, continually builds and modernizes applications for the benefit of its constituents and to make County processes more efficient.

Facing an aging portfolio of SharePoint applications — and the departure of the sole SharePoint developer — ITD used the Claude Code AI development agent to migrate legacy pages to a modern React and .NET Core stack, achieving a 13× speed improvement over the traditional approach.

Here are the applications ITD built and put into production using this AI-assisted approach.

Live Application Solutions

PWA Maps Tracker ● Live in Production

The Public Works Agency map and survey records tracking system. Maps Tracker manages the full lifecycle of survey map submissions — from intake and examination through surveyor approval, payment sign-off, and final filing — replacing a legacy SharePoint site while preserving every business rule.

  • Map submission tracking & examination workflow
  • Records of Survey (ROS) application approval
  • Surveyor & surveying-company registries
  • Payment report signing & POS surveyor approval
  • Dashboards with live charts and operational reports
  • APN / parcel lookup, street and staff management

Stack: React 19, Redux Toolkit, AG Grid, Highcharts, Azure AD (MSAL) single sign-on, .NET Core REST API. Automated end-to-end tests with Playwright.

PWA Budget & CIP ● Live in Production

The Public Works Agency Budget and Capital Improvement Program (CIP) management application. It centralizes budget development, program narratives, capital project tracking, and quarterly reporting — organized by department and fiscal year — on a modern, secure platform.

  • Budget Development by department & fiscal year
  • Budget Narratives authoring & review
  • Capital Improvement Program (CIP) project tracking
  • Quarterly Updates & status reporting
  • Key Dates calendar for budget-cycle deadlines
  • Document management with large-file support

Stack: React, Azure AD (MSAL) single sign-on, .NET Core Web API (Budget, CIP, Documents, Calendar, Fiscal Years, Departments).

The Challenge

ITD’s aging SharePoint applications relied on a Dream Factory API layer that had become unsupported and fragile, and the contract for the sole SharePoint developer was ending — taking undocumented institutional knowledge with it. A traditional rebuild demanded a five-person team (Business Analyst, Developer, QA, UAT Tester, Support Engineer) and roughly six months of effort, at 2–5 days per component with inconsistent quality. The County needed a faster, consistent, repeatable path.

How We Built It

A single reusable five-stage pipeline, driven by the Claude Code AI agent, ran once per legacy page: (1) Understand the legacy file, (2) Convert to React TypeScript, (3) map the SharePoint API to .NET Core endpoints, (4) generate unit & E2E tests, and (5) Log migration notes. Quality standards were encoded once in a CLAUDE.md file so every component followed the same structure, naming, and API patterns — from the first page to the last.

Why it worked: a large context window read all pages at once, autonomous execution planned and acted without hand-holding, a self-correction loop caught and fixed its own errors, and encoded standards kept quality consistent across every page — no drift, no rework pile-up.

consistent quality, tests on day one

One developer delivered work previously requiring a five-person team, with test coverage from day one and every migration decision auto-documented — preserving institutional knowledge in writing rather than in people. The complete toolkit (agents, skills, sample prompts, and scripts) is published openly so any California county can reuse it: github.com/alcoitd/AI-Dev-KnowledgeBase.
