00 / KAREL HERNANDEZ RODRIGUEZ · AGENTIC SYSTEMS · BUILT ON 20 YEARS OF OPERATIONS
I design, build, and run production AI agent systems for mid-market companies — fixed scope, measured outcomes, every action logged with a receipt. Twenty years of keeping business infrastructure alive taught me to build things that keep running. Not a consultancy that ships decks.

01 / THE PROBLEM
Big firms sell strategy and hand the build to juniors. Automation freelancers ship flows that die in production. Platform vendors sell tools without governance. The gap between them is where your margin is going — and where I work.
WHAT YOU'VE BEEN OFFERED
HOW I WORK
The consultants who can strategize can't build. The builders who can build have never run a business. I've done both for twenty years.
02 / WHAT I BUILD
Fixed scope, fixed price, fixed timebox — never hourly. Start with the audit; every step after it is a decision you make with evidence in hand.
S-01 · 2–3 WEEKS
Where agents pay for themselves — with the math.

S-02 · 30 DAYS TO PROD · 45 ALL-IN
THE FLAGSHIP
One agent, in production, in 30 days.
from $24,000fixed scope
S-03 · ONE–TWO 90-DAY CYCLES
The agent system that runs a department.
from $60,000milestone-billed
S-04 · ONGOING
Your fractional AI officer — plus the crew that keeps agents sharp.
from $6,500/moquarterly terms · 90-day decision points
THE AUDIT MATH — YOUR INPUTS · YOUR NUMBERS
That's today's cost of the work — not a savings promise. The audit's job is to find where, and whether, agents can carry it. If it can't find 3× its fee in annualized savings, you don't pay.

03 / EVIDENCE
Everything on this receipt is countable in a repository or a public channel. No client logos I can't back, no invented outcomes — engineering facts, printed.
Before I sold any of this, I built two full agentic platforms of my own. They are the lab: every pattern I deploy for you — permission ladders, approval gates, agent memory, receipts — is already running in production there. You buy patterns that exist, not experiments on your dime.
KAREL.BUILD — ENGINEERING RECEIPT
VERIFIABLE FACTS ONLY · REV 2026.10
E-01 · AGENTIC WORK-CREW PLATFORM
Ten named agents — intake, reception, drafting, sales, review — operating under a default-deny permission ladder. Every action needs an explicit grant; every output is saved as an immutable receipt. Built for regulated work: legal, insurance, claims.
E-02 · COMMUNITY PLATFORM + AGENT RUNTIME
A revenue-bearing learning platform with agents woven through it: multi-provider model routing, two-tier persistent memory with cited sources, plan-approval gates on every risky action, and Stripe Connect money flows underneath.
E-03 · THE OPERATING BASE — SINCE 2004
The managed-services firm that has kept Los Angeles law firms and mid-market companies running for two decades. Uptime culture, security posture, and the domain knowledge of how work actually moves through your systems.
E-04 · THE TEACHING CHANNEL
Where I teach AI and automation, in English y en español. Change management is teaching — and teaching is a practiced muscle.
04 / ENGAGEMENT SEQUENCE
Every engagement runs as a contained 90-day cycle with a hard decision point at the end: scale, continue, or stop. Here's the first cycle, day by day.
DAYS 01–14
Workflow mapping, systems inventory, data readiness. The industrial-engineering pass: where hours go, what they cost, what an agent could carry.
DAYS 15–21
Scored opportunity map on the table. Build, buy, or wait — each verdict with the math attached. You choose the pilot with evidence, not enthusiasm.
DAYS 22–52
One agent into production: wired to your systems, gated by human approval, logging receipts. Your team trained while it's built, not after.
DAYS 53–83
Agent runs against the baseline I captured on day one. Hours saved, response times, cost per unit of work — in a report you can hand to the board.
DAY 90
Scale it, continue it, or stop. Every quarter ends with that decision in your hands. That's the whole deal — no lock-in, just receipts.
05 / THE OPERATOR
I'm Karel Hernandez Rodriguez — industrial engineer, founder of Zoltis Technologies, author, and builder of two agentic platforms. When you hire me, I'm who shows up. The bench behind me is silicon.
“I spent twenty years keeping other people's systems alive. I'm not going to hand you something I wouldn't operate myself.”
— KAREL HERNANDEZ RODRIGUEZ
2004
Founds Zoltis Technologies. Managed IT for Los Angeles law firms and mid-market companies — uptime, security, and the discipline of being the one they call at 2 a.m.

06 / OBJECTIONS, HANDLED
These are the questions operators actually ask me — answered the way I'd answer across a table.
That fear is why my systems are built the way they are. Agents operate under default-deny permissions: they can't send, publish, or modify anything without an explicit grant, and risky actions park at a human approval gate before anything leaves the building. Every action is logged with an immutable receipt, so 'what did the AI do?' is answered in seconds, not days.
07 / START THE SEQUENCE
Two to three weeks. $9,500, credited toward the pilot. If I can't find three times the fee in annualized savings, it's free — and either way you keep the roadmap.
