ROBOTICS / ROS 2
Robot navigation and control
Personal robotics projects involving lidar navigation, sensors, motors and the software that coordinates them. They let me test how code responds to movement and imperfect sensor readings.

Apps, websites and automation
What would you like to build or improve?
You don’t need a technical brief. A short description of your idea or the problem is enough to start.

I have an app idea
A booking app, a customer portal or a tool for your team. Tell me what people should be able to do.
I want to save time on tasks
Copying data, sorting documents or updating several systems. Tell me which task takes too much time.
I need a website
A new site, a page for a specific service or a redesign. Help visitors understand your business and contact you.
01 /WHAT I BUILD
Software development services, from websites to robotics
A new application, a clearer website or less manual work. I can start from an idea or improve the tools you already use.
You don’t need to know which technology to use. Tell me what you want to achieve.
01Websites
Business websites and landing pages that explain your offer and make it easy to contact you. I take care of design, development, loading speed and the technical foundations for search.
Custom Website Development, Freelance & Remote02Custom applications
Web applications and internal tools for bookings, customers, orders or invoicing. I adapt the software to your workflow and connect it to the tools you already use.
Custom App & MVP Development03Mobile apps
Apps for Android and iPhone, from an early concept to development. We define the essential features first, then choose the platforms and integrations the app needs.
Custom App & MVP Development04Business automation
Reduce repetitive work such as copying information between tools or processing documents. I connect your systems and add checks or human review where needed.
Business Process Automation05Connected devices & robotics
Software, electronics and sensors for connected devices, home automation and robots. We first check what can be tested remotely and what equipment the project needs.

Describe my idea06Search & AI visibility
Clear content, fast pages and technical SEO help search and AI systems understand your website. I work on these foundations; rankings and citations cannot be guaranteed.

Describe my idea01.5 /ELECTRONICS AND PERSONAL PROJECTS
Electronics and robotics.
I also learn through personal projects: robots that navigate using lidar, sensors and boards such as Arduino and ESP32. One of those projects became iGrow, an automatic controller for growing conditions. Working with physical devices has taught me to test the hardware and software together.

ESP32 / ARDUINO / IOT
Sensors and connected devices
Small programmable boards can read sensors, send alerts and control devices. I used them to prototype iGrow and to explore home automation.
SECURITY / BUG BOUNTY
Security and reverse engineering
I study how programs work, look for weaknesses within bug bounty programme rules and report what I find. That experience informs how I design accounts, data access and integrations.
AGENTS / RPA
AI agents and automation
AI agents use tools to complete several steps of a task. In my automation work, I connect them to business data and define which actions need human review.
