Profile

Fullstack developer with a track record of shipping web and mobile applications end to end, from database design to the interface the end user works with. I have built automotive service management, logistics and invoicing systems, along with personal projects taken all the way to production. AI-assisted development —agents, tools, MCP and hooks— is part of my daily engineering process, not an add-on.

AI-assisted development

I use AI as part of the engineering workflow, not as autocomplete. I build and configure agents for concrete project tasks: automating reviews, keeping API contracts in sync across repositories and speeding up repetitive work without losing control over the code that ships.

  • 01

    Agent-based development: defining tasks, context and boundaries so an agent can work on a real repository with sound judgement.

  • 02

    Custom skills and tools: reusable procedures that capture project knowledge and make it repeatable for the whole team.

  • 03

    MCP (Model Context Protocol): connecting agents to each project's internal data sources and services.

  • 04

    Hooks: automating validations and checks that run on their own with every change.
