How I can help

Custom web apps and systems

Platforms, dashboards and internal systems built for you so your team works better, and easy to maintain over time.

Mobile apps

Apps for iPhone and Android, built once for both.

Technical consulting

I review your system and your team, find what holds your growth back and propose how to organize it. Then I help you carry it out.

AI assistants and agents

Assistants that answer your customers and agents that carry out tasks for you, built for you and connected to your business information and systems.

Video games

I also design, program and publish games with my own studio, Kipu Games.

Real cases

Results, without jargon.

Banking

Bank apps and systems used by hundreds of thousands of people.

I led a team of 5 to 8 developers and built tools that save them time.

Technology: React Native, Expo, AWS, Go

Visibility

A website that loads faster and climbs in Google.

I changed how the page is built so Google reads it better and it loads faster.

Technology: Angular, SEO

Operations

5 areas of the operation in a single system.

I brought orders, spare parts, machines, tasks and staff into a web and mobile app with clear reports.

Technology: Angular, PWA, React Native

Growth

Apps and systems that grow without breaking each other.

I split the system into independent pieces so one can improve without affecting the rest.

Technology: Angular 15, 16 and 18, Microfrontends, Node

Artificial intelligence

AI assistants and agents running in real projects.

I connected custom assistants and agents to the company's information and systems, so they answer and also carry out tasks.

Technology: GPT API, AI agents, Python, Node, MongoDB

How I work

I lead your project from start to finish. When the project calls for it, I assemble a team of trusted professionals to fit, so nothing depends on a single person.
