02 / How I can help

AI consulting.
From strategy to build.

You work with the person making the technical decisions. From the first business question to the system your team uses.

Discuss an engagement
01

AI strategy & value creation

Find the opportunities that deserve investment. I assess the workflow, data, economics, and risks, then help you choose what to build, buy, or leave alone.

Opportunity assessment · Business case · Delivery roadmap

02

AI harness engineering

Build the environment that makes a model useful: well-designed tools, bounded agent loops, guardrails, context, memory, and orchestration. Tested against the work your team actually needs done.

System architecture · Working integrations · Evaluation & observability

03

Data & decision systems

Turn fragmented data into something you can act on. My work spans investment research, financial operations, open banking, risk models, and operational analytics.

Data pipelines · Decision support · Auditable workflows

04

Technical leadership & adoption

Work with a former CTO who can connect the business discussion to engineering decisions. I stay involved in the build and help your team understand, operate, and improve what we ship.

Inside the build / AI harnesses

The model is a beginning.
The harness makes it useful.

01 / Tools

Give the model a way to act.

Connect business systems through clear interfaces, scoped permissions, and validated inputs. Tool calls should be understandable, observable, and safe to retry.

THE DESIGN QUESTION

What can it access, and what is it allowed to change?

Select a component to explore its role.

DESIGNED FOR REAL OPERATIONS

Quality, permissions, cost, and human oversight belong in the architecture from day one.

03 / The SFAX approach

The SFAX framework.
For business operations.

Strategic Framework for AI Excellence.

SFAX is my way of connecting strategy, evidence, engineering, and execution. Each stage answers a business question and ends with something concrete.

S / 01

Set the direction

Name the business problem, the decision to improve, and the person who owns it. Agree what a useful result looks like.

YOU LEAVE WITH

A clear problem & success criteria

F / 02

Frame the value

Test the data, assumptions, feasibility, and economics. Compare the simplest viable options before committing to a build.

YOU LEAVE WITH

A business case & a practical plan

A / 03

Architect & build

Design the harness, connect the tools, and evaluate it on real tasks. Make failure paths and human oversight part of the system.

YOU LEAVE WITH

A tested system in your workflow

X / 04

Execute & improve

Measure quality, cost, and adoption against the starting point. Document the system and give your team the means to own it.

Measured results & team ownership

04 / The person behind the work

Youssef Ben Mahmoud

A MATHEMATICS ENGINEER
WHO LIKES TO BUILD.

Youssef Ben Mahmoud.

I’m an AI expert, mathematics engineer, and former CTO. SFAX brings those perspectives into one practice.

Over 10+ years in enterprise AI and technology, I’ve led engineering teams, managed roadmaps and budgets, and built systems across finance, retail, and AI infrastructure.

My mathematical training makes me careful about assumptions and uncertainty. My experience as a CTO keeps me close to delivery, cost, and the people who will use the system. I’m comfortable in the leadership conversation, and I stay involved in the code.

Make a clear decision. Build what matters. Know whether it worked.

05 / Start a conversation
