Sound familiar?
The busywork that quietly eats your week
Most small businesses don't need “an AI strategy.” They need hours back from the work nobody likes doing. These are the usual suspects.
Leads that slip through the cracks
Web forms, calls, and texts nobody answers in time. Capture, sort, and follow up on every one, fast.
Scheduling and dispatch by phone
Jobs, crews, and appointments juggled in someone's head. Let software propose the day; you approve it.
The same customer questions, every day
Hours, prices, order status. An assistant that answers from your own information and hands off to a person when it should.
Spreadsheets nobody trusts
Numbers copied between files until no one knows which one is right. One clean source, and reports that build themselves.
“We tried ChatGPT and it didn’t stick”
A generic tool doesn't know your business. Fitted to your workflow and your data, the same AI becomes genuinely useful.
How it works
From a conversation to results you can measure
Four steps, no jargon. We only build what clearly pays for itself.
- 01
Free discovery call
30 minutes to learn your business and where the hours go.
- 02
Process review
On-site or remote, we map how work actually flows and where it leaks.
- 03
AI roadmap
Two or three prioritized opportunities, each with effort, cost, and payoff.
- 04
Build & train
We implement, train your team, and measure the result against today.
Your tools, not new ones.
We work inside what you already use (Google Workspace, Microsoft 365, QuickBooks, your CRM) instead of making you switch.
Why personalized
Generic AI doesn't know your business. We take the time to.
The tools are everywhere. What's missing is someone who understands your context well enough to know where they help, and where they don't.
Context first
We start with how your business runs (your customers, your team, your margins), not with a tool looking for a problem.
Real depth behind the advice
Founder-led by a PhD in operations research who has built AI and optimization systems for banks, insurers, and logistics fleets. The same rigor, sized for you.
Local, and in person
Based in Kennesaw. Happy to sit down at your shop or office across Cobb County and metro Atlanta, and remote anywhere in the US.
Proof of depth
The same engineering, sized for you

Research & publications
PhD in Operations Research from ITA and Universidade Federal de São Paulo (plus a BSTech in Computational Mathematics). His doctoral work produced SIROM — a sampling-based robust optimization method that matched or beat the literature in 92.5% of cases — a distance-geometry method for 2D target location under uncertainty, and “Hardness,” a robustness measure for solutions under uncertain parameters. Every BIS engagement is built on that foundation: science, not model wrappers.
Selected publications
- A sampling-based multi-objective iterative robust optimization method for the Bandwidth Packing Problem
- Target location by a wireless sensor network from interval distances
- Forecast UTI: predicting intensive-care-unit beds during the COVID-19 pandemic
- A heuristic method for optimization under uncertainty based on Monte Carlo simulation
- Efficient frontier of credit risk using Monte Carlo simulation
