Tizbi has shipped software for mid-market and enterprise clients across pharmaceuticals, manufacturing, construction, education, B2B commerce, real estate, water treatment, and call-center operations since 1998. Through 2025–2026 we re-platformed our delivery model on a custom AI operating layer (Anthropic Claude API, Agent SDK, MCP, persistent memory, 150+ domain skills, multi-tenant prompt architecture) and shipped 50+ production systems in 16 months.
Below: 40+ representative projects across industries. AI-flavored systems are foregrounded and marked with the blue rail. Client names are redacted where engagements are confidential; the Tizbi public case studies section and historical references on the public resume retain their client names.
A "Human Language" analytics interface: an operator asks a question in plain English, Claude generates SQL against a documented schema, executes it, and interprets the result with a confidence score. Schema understanding lives in 158 database-stored description rows — new tables become queryable with zero code changes. Runs over a normalized 18-table model (1,326 jobs, 1,233 customers); paired with a Whisper + Claude call-extraction pipeline and bilingual cash-flow analytics. Productized into Saxila AI with live website and accepted into the F6S Pitch Elk Grove 2026 startup competition.
Stack: Claude API, .NET 10 Razor Pages, Azure SQL, Whisper STT, Python ETL
Production AI system that answers business questions over every inbound customer call — "RAG without vectors": pure SQL retrieval plus Claude, no GPU, no model training. Dual-strategy engine: preset keyword classification, plus a "smart" mode where Claude reads the full schema, generates a targeted SQL query, executes it, and interprets the result. Operates over a 490,000+ record call-metadata store covering 18,000+ unique calls and 27 metadata codes; direct-SQL mode classified a full 12-month population (5,077 calls × 11 codes) in under 60 seconds at roughly $0.10–0.30 per query.
Stack: Claude API, Azure SQL, .NET Razor Pages, SQL-injection sanitization on model-generated clauses
Research-stage product that takes natural-language design intent from a structural engineer and produces verified 3D engineering geometry — with built-in verification rules, design code checks, and quality gates. Working prototypes have demonstrated a new conversational pattern for AI-assisted CAD: replacing point-and-click drafting with intent-driven generation, then validating the result against engineering rules before it ships. Internal architecture & IP details withheld pending patent filing.
Demonstrates: AI-assisted CAD, rules-based verification, multi-agent guardrails, agentic design workflows
Multi-tenant data platform that collects from 5 marketing APIs (Google Search Console, GA4, Google Ads, GTM, Bing Webmaster) into 36 Azure SQL tables, with AI features layered on top. Cross-source PageProfile view links organic rankings + paid spend + traffic + conversions per page. AI "Ideas" feature calls Claude with RAG-enriched prompts; content pipeline produces AI-drafted strategic briefs; a 9-rule conversion-health detector flags broken Google Ads conversion tracking. Multi-tenant master prompts in Azure SQL with hard-fail validation.
Stack: Python collectors (PyInstaller EXE), .NET 10 Razor Pages, Azure SQL, Google APIs, Bing API, Claude API
AI call-review system that turns recorded sales calls into structured Q&A data and scorecards.

Model-agnostic design enabled a clean migration from OpenAI to Claude with feature parity.
Stack: VB.NET / Python, Claude Sonnet 4, Azure SQL, SOAP integration service
Multi-tenant CRM platform running two isolated production deployments — a Tizbi-internal contact/lead system and a marketing instance for a manufacturing client with 43,000+ rural contacts (architects, building officials, contractors). Four AI email agents run daily: BuildingOfficialFollowUp, ArchitectFollowUp, ProspectFollowUp, InactiveCustomersFollowUp. Each agent uses Claude Sonnet 4.6, a database-stored prompt-template system, per-run logging, and a reviewer loop.
Stack: .NET Web API, Azure SQL (dual backends), Claude Sonnet 4.6, Python agent runners
Autonomous discovery agent that runs unattended on a schedule — one city per hour, Claude + web-search tool discovers architecture firms, scrapes team pages, classifies leads into quality tiers, dedups, and pushes new records to a CRM API. Scale to date: 8,789 architects and 1,571 firms discovered across 900+ cities. Runs unattended at roughly $48–165/month in API cost.
Stack: Python, Claude Sonnet + Haiku, web search tool, Azure SQL, Windows scheduled tasks
End-to-end AI workflow that takes a new customer's credit application from the inbox to a risk recommendation. Pulls PDF applications from Gmail, parses applicant identity, performs web research, drafts reference-check emails, tracks responses, and produces a risk assessment with recommendation routed to the CFO. Replaces what was previously several hours of manual due diligence per applicant.
Stack: Python, Claude API, Gmail API, web search, QuickBooks API
Reusable email-analysis service that scans Gmail for unreplied threads, identifies action items, distinguishes To vs CC, ignores already-handled threads, filters newsletters/security alerts/cold outreach, and ranks correspondents by an importance score. Hardened after a v1 baseline that scored 0/19; v2 rule-set added explicit name-mention and request-pattern detection.
Stack: Python, Gmail API, Claude API, Azure SQL
Custom AI operating layer built on Claude that turned Tizbi's shipped-systems velocity from team pace to a single-architect pace. Five components: persistent file-based memory (structured user / feedback / project / reference memory across all sessions); 150+ domain skills (self-contained operating manuals for each client, project, infrastructure component, and workflow); MCP (Model Context Protocol) integrations for Gmail / Drive / Calendar; multi-tenant master-prompt architecture (per-company prompts in Azure SQL with reviewer loop + hard-fail validation); and a multi-agent development workflow orchestrating OpenAI Codex and Claude Code as co-developers with rotating builder/reviewer roles and cross-agent code review.
Stack: Anthropic Claude API, Agent SDK, MCP, OpenAI Codex, Azure SQL, centralized TokenStore
Rules-based validation gate that sits between an AI agent proposing structured actions and the system executing them. Three-way contract: accept, reject with reasons and alternatives, or flag the unknown and log the gap. Hardened through adversarial red-team campaigns where an AI agent submits batches of deliberately-invalid actions and every false-accept becomes a logged rule to close. A campaign caught a fail-OPEN exemption and re-architected it fail-closed; 169 unit tests with full regression clean.
Stack: .NET, Claude API, multi-agent development (Codex + Claude Code)
