Automate your processes, onboardings, invoicing, collections, approvals, reports, support and documents
Every hour your team spends moving data around is an hour not spent on clients. Let’s find those hours and give them back.
Let’s talkClient onboarding
New clients get a smooth start without anyone chasing paperwork: contract, access, folders and kickoff, set up in minutes.
Sales follow ups
No opportunity forgotten. Every contact lands in your CRM with context, and reminders and follow ups go out on time.
Invoicing and collections
Invoices go out the moment the work is done, reminders before payments are late, and accounting that always matches.
Internal workflows and approvals
Requests reach the right person and get approved in one click, with a trail you can check later.
Reports and data
The numbers you need, up to date and in one place, instead of a Monday spent copying spreadsheets.
Customer support
Faster answers on WhatsApp and email, with AI drafting the replies and your team keeping control.
Chat with your tools
Your tools stop being places you go to look things up. You ask, Claude checks your systems and does the work.
Claude Skills, set up for you
Skills that know your processes, your tone and your templates: proposals, reports, onboarding checklists. Customized and shared with your whole team.
Secure integrations via MCP
Claude reaches your CRM, billing, files and databases through MCP servers I build and host. Scoped permissions per tool, read only where it should be, and your keys stay on your side.
Chat with your tools
Ask questions and get answers with real numbers. Then ask it to act: send the reminder, update the deal, post in Slack. From Claude, Slack or your own app.

About me
I build AI first products, tools and automations from Buenos Aires, Argentina. With over seven years of experience, I help small businesses and startups replace manual work with systems that fit how they actually operate, from the first idea to something running in production.
Coming from Digital Marketing and Multimedia Design, I think about the business and the people using what I build, not just the code. Today I work AI first: I build custom tools and products end to end, choosing the stack each project actually needs. I connect AI to company systems through MCPs, Skills and harnesses, and I design the automations behind them, with the fallbacks that keep them running when something fails. I also build commercial landing pages and front ends, email flows and SEO.
As a consultant and former lead Automation and Frontend Developer at an Automation Agency, I’ve worked with diverse clients to scale their digital presence and optimize their business processes. I am committed to helping businesses grow by leveraging technology, automation, and design principles tailored to their unique needs.
I’m driven by a love for technology. In my personal time, you’ll find me automating my smart home and developing tools to enhance my workflow. Outside of tech, I am passionate about calisthenics, fitness, travel and food.
I develop deep, long term relationships with my clients
