Built for
what's next.

I'm Jacob. One engineer with an AI engine — building agents, automations, dashboards, and custom systems that ship in weeks, not quarters. From SMBs that need a working booking flow this Friday to a city responding to 925K resident calls a year, the work is the same: solve the actual problem, fast, and let the code do the rest.

Track record

Real projects. Real clients. Real systems running.

From GSIB-bank treasury operations to the City of Charlotte's 311 system to Charlotte small businesses — same playbook, different scale. No marketing-team case studies.

Forecast-Over-Forecast Delta Finder & Explainer

Agentic system that compares week-over-week financial forecasts, flags material variances, and writes the narrative explanation a treasury analyst would otherwise spend half a day producing. Same intelligent pattern-detection-with-explanation we apply to citywide case clusters, SLA-risk surfacing, and equity dashboards in the Vault CRM.

Inbox-Polling Excel Refresh Agent

Watches a treasury inbox, detects when source data lands, validates it, refreshes the relevant Excel forecast models, and republishes outputs — without anyone touching Excel. Architectural parallel to our automated email-channel intake, case-context update, and proactive resident notification flows in the Vault CRM.

311 Automation Demonstration — six call types

Working AI-handled intake demonstration built specifically for the City of Charlotte and presented to the City's AI and technology stakeholders. Six end-to-end 311 call types running, agent-handoff included, evidence-of-work artifacts shown live. The engagement that led directly to the Vault's invitation onto the City's CRM RFI.

RFI Response · City of Charlotte

Vault CRM — unified 311 + AI case management

The City fields ~925K 311 calls a year across agents toggling between 15+ applications per resident interaction. The Vault's RFI response is a unified intake workspace — phone, web, SMS, email all funnel to one conversation thread, AI assists agents in real time, and a deflection layer handles routine requests before they ever reach a human. Hosted in the City's own AWS Bedrock tenant. NIST 800-53 control mapping in flight, SOC 2 / ISO 27001 roadmap drafted.

The Vault — Sovereign AI for Lawyers

Vite + FastAPI legal intelligence platform. Multi-pass document extraction, swappable AI backend (cloud Bedrock or fully local on-premise), audit-grade logging on every call. The architecture proves the data-sovereignty pattern we offer Charlotte: tenant isolation, swappable model layer, no third-party model exposure of sensitive content. The same chassis works for healthcare, finance, and government.

Production AI & software for Charlotte small businesses

Live deployments across auto repair, restaurants, salons, home services, healthcare, and professional services: AI receptionist, quote-by-photo intake, owner nightly reporting, listing landing-page generation, recall and review automation. Powered by an internal agentic engine — Henry (Claude Opus) reasons and opens tickets, Bob (MiniMax) executes builds and outreach across a 5,277-firm pipeline. The same agents that scale Vault internal ops scale the small businesses we serve.

What I build

Building the future,
one client at a time.

I don't do enterprise procurement or 12-week discovery phases. You describe the problem, I quote a price, we ship it. The Vault AI grows with the future — every new model, every new technique, every new capability becomes a tool I bring to your business.

Industry doesn't matter. If the problem is real, I can probably help.

AI agents & autonomous workflows
Agents that handle real work — not chatbots. Built with Claude, GPT-4o, or open-source models. Multi-step reasoning, tool use, memory.
Custom AI trained on your data
RAG systems, fine-tuned models, internal copilots that know your business cold. Practical, not a science project.
Business automation
Email sequences, scheduling, invoicing, lead routing — the repetitive stuff still done by hand. Now it runs while you sleep.
Custom web apps & dashboards
When off-the-shelf SaaS doesn't fit. Full apps with auth, payments, admin panels, real-time data.
Websites & landing pages
Built to convert, not to win design awards. SEO, speed, mobile — the basics, done right.
System integrations
Connect the apps that don't talk. CRM + accounting + calendar + voice + email + whatever else lives in your stack.
Voice AI & conversational interfaces
AI voice agents that handle real calls — booking, support, screening. Live in 2 weeks, not 2 quarters.
Private AI infrastructure
On-premise AI for industries where data can't leave your building — law, healthcare, government, finance.

Who I am

Jacob Krzeminski

I run The Vault AI out of Charlotte, NC. I help businesses move at AI speed — building agents, automations, dashboards, websites, integrations, and the custom systems that solve real problems. AI is my development engine, which means I ship what used to take an agency 6 months in 3–6 weeks, for a fraction of their price. I'm not hiding it. It's how I compete.

I work with restaurants, law firms, healthcare practices, city governments, real estate brokers, contractors — anyone with a problem they've been putting off. Industry doesn't matter. Whether it's tech, ops, marketing, or internal tooling — if the pain is real, I can probably help.

I don't disappear after delivery. I don't hand your project to a junior. Every build gets my direct attention from kickoff to launch — and I stand behind it after.
