Everything else is passed on to you. - **Keep an eye on your market**: Competitors, tenders, prices, regulations: it watches, reads and sums up what matters. - **Prepare your reports**: Every morning or every week, your numbers and what needs attention, without opening a spreadsheet. - **Keep your tools up to date**: CRM, spreadsheets, accounting, project management: it copies, syncs and checks for you. - **Your data, protected**: Encrypted access you can revoke at any time, and a local model when nothing should leave your premises. - **Always on**: Running on a server, it restarts on its own if something goes wrong and alerts you if it stops. - **Costs under control**: A small model to sort, a large one to write, caching and a spending cap: every cent is tracked. #### Its interfaces - **In your messaging app**: Telegram, WhatsApp, Slack or Teams: you message it like a colleague, and it replies, suggests and gets things done. - **Approval in one click**: When an action needs your go-ahead, it brings it to you ready to send. - **A briefing every morning**: What got done, what's waiting for you, and what it cost. - **A dashboard**: A log of every action, plus costs, settings and safeguards, in a clear interface. #### Frequently asked questions about agents - **Is my data safe?** The agent only accesses what its task requires, through encrypted access you can cut off at any time. When data must not leave your premises, it can rely on a model that runs locally. - **What if it makes a mistake?** Anything that commits your business needs your approval. Everything else is logged and reviewed by a second model, and I fine-tune its behavior during a trial phase, before it acts for real. - **How much does it cost to run?** It depends on volume, but model costs usually stay modest. They're tracked to the cent, with a cap you set. - **Do I need to change my tools?** No. The agent plugs into what you already use: your email, calendar, CRM, spreadsheets and accounting. ### Native apps — Custom iPhone, Android and macOS apps: smooth, integrated with the system and a pleasure to use. - Page: https://eliesluismans.com/en/work/apps - Summary: Mobile apps for iPhone and Android in React Native, and native macOS apps in Swift and SwiftUI, like the ones I built for my own needs: integrated with the system, fast, dependency-free, and local when needed, AI included. - Technologies: Swift, SwiftUI, Expo / React Native, Firebase, TypeScript, Supabase, Apple Vision, FFmpeg, Pandoc, GitHub - **Mandarine** (2026, Productivity, personal project): Convert, retouch and file a document in a single gesture: a wheel opens under the cursor. - Features: Conversions: 275 combinations across 45 image, audio, video and document formats ; Editing tools: 27 tools for photos, videos, audio and PDFs ; Actions: six quick actions, including sharing ; 100% local: no file is ever sent to a server, and the app is free. - **Cleaner** (2026, Utility, personal project): Free up space on a Mac without anything deleted behind your back: everything is explained, nothing goes without your OK. - Features: Scan: 1.3 million files reviewed in 50 seconds, read-only ; Thirteen cleanup categories, ranked by risk level ; Everything explained: where each item lives, what it's for, what happens if you delete it ; No deletion without explicit confirmation; personal files go to the Trash. #### Cleaner's principles - **Read-only**: The scan changes nothing. Every deletion goes through a list to check, path by path, then a confirmation. - **Everything explained**: Each item shows where it lives, what it's for and what happens if you delete it. - **The right method**: What regenerates (caches, logs) is erased. Personal files go to the Trash, where you can still recover them. ## Education ### Groupe Scolaire Claude Monet — French education in Morocco - Place: Mohammedia, Morocco - Period: Until 2015 - Primary and middle school in the AEFE network of French schools abroad. ### Lycée Français Lyautey — Diplôme national du brevet (French middle-school diploma) - Place: Casablanca, Morocco - Period: 2015 – 2017 - Honors: Highest honors - End of middle school at the French high school in Casablanca. ### Notre-Dame des Champs — CESS (Belgian high-school diploma), general track, English and Spanish - Place: Uccle, Brussels, Belgium - Period: 2017 – 2020 - End of secondary school in Brussels. ### EPHEC — Bachelor's in E-Business · Business Analytics specialization - Place: Woluwe, Brussels, Belgium - Period: 2021 – 2024 - Honors: With distinction - Development, data, digital marketing and IT project management.

Mostly startups, solopreneurs and small, agile teams, in Belgium, France and across Europe. I also occasionally work with teams at larger companies on consulting or innovation projects. ### Do I work remotely? Yes. I'm based in Brussels and happy to travel within Belgium and neighboring countries, but most projects run remotely, with regular video calls. ### How much does a project cost? It all depends on the project. I adapt to your actual needs as well as your budget. What I build (website, software, AI agent or app) is quoted at a fixed price, set after a free first call. Consulting, audits and ongoing support are billed by the day or the hour. ### How quickly can we launch an MVP? It depends on the project. I commit to delivering a first usable version as fast as possible: very often within a few weeks, sometimes within a few days. It then evolves until launch, with regular progress updates. ### Can I take over an existing project? Yes. I start with an audit of the code and the infrastructure, then propose a plan to stabilize, improve or evolve the product. ### Which languages do I speak? French, my native language, and English, which I speak fluently and in which I consume most of my technical content, written and spoken: both work just as well for conversations as for deliverables. I also get by in Spanish and know the basics of Dutch.
