Hello, I'm
Salim Soltani.
Also known online as Catuleius
Product Manager who builds what he envisions.
I bridge business strategy and technology — combining a Master's in Business & Management with hands-on experience building real products. Currently leading treasury operations at Grands Moulins Belghith, while driving product thinking across every venture I touch.
01. About
Who I Am
Hello! I'm Salim — a Product Manager with a rare technical edge. My academic foundation is a Master's degree in Business & Management, but I've always been drawn to the intersection of strategy and execution.
I taught myself Flutter, PHP, and MySQL — not to become a developer, but because understanding the "how" makes me a better PM. I can translate business goals into precise product requirements, work alongside engineers fluently, and prototype ideas when speed matters.
Today I serve as Section Head of Treasury at Grands Moulins Belghith, where I manage financial operations while bringing a product mindset to process improvement. I also hold an IBM Professional Certificate in Mobile Application Development and several Coursera certifications.
I operate across two domains:
Product & Business
- Product Strategy
- Roadmapping
- User Research
- Financial Management
- Operations & Process
- Business Analysis
- Stakeholder Mgmt
- Agile / Scrum
Technical Skills
- Flutter & Dart
- PHP REST APIs
- MySQL
- Firebase
- Sqflite / Hive
- GetX
AI & Prompt Engineering

- Shipped multiple live products including a desktop POS/ERP for butcher shops (Carnis Vente), a habit tracker on Google Play (My Day Flow), and a trivia app (Pip Master).
- Leverage AI tools — Claude, ChatGPT, and custom prompt workflows — to accelerate product discovery, write PRDs, and prototype UI architecture faster.
- Operate as a solo PM-founder: balancing technical decisions with user needs and business viability across every sprint.

02.5. AI & Problem Solving
AI in My Workflow
I use AI not as a shortcut — but as a thinking partner. Certified in Prompt Engineering for ChatGPT from Vanderbilt University (Coursera), I apply structured prompting techniques to real product work every day.
Where this shows up most is in UI architecture and problem solving: I use AI to sketch information hierarchies, challenge my design assumptions, generate user flow alternatives, and pressure-test product decisions before a single line of code is written. This shortens the discovery loop dramatically.
As a solo PM-founder at Catuleius Softwares, AI tools let me operate with the leverage of a team — producing PRDs, spec drafts, competitive analysis, and prototype briefs faster and more rigorously than working alone ever could.
UI Architecture
Use AI to map component hierarchies, screen flows, and interaction models before wireframing — turning vague requirements into structured blueprints.
Problem Solving
Frame product problems as prompts — iterate on root cause analyses, prioritisation frameworks, and decision trade-offs using AI as a critical sounding board.
PRD & Spec Writing
Generate structured product requirement documents, user stories, and acceptance criteria — then refine them in dialogue with AI until they are engineering-ready.
Vanderbilt Certified
Prompt Engineering for ChatGPT — Vanderbilt University / Coursera (2025). Applied daily across product discovery, content, and technical research.
