Custom Software That Does Exactly What Your Business Needs
When no off-the-shelf tool does what you need, I build one that does. Internal management systems, process automation, customer portals, data dashboards, and complex integrations. I'm based in Chile and work with US businesses on US time zones.
More than a standard website
A custom web application is a complete system: it automates processes, centralizes information, and gives your team tools that didn't exist before. Here's what I build.
Architecture that scales with you
I plan the system from the start so it can grow with your business, without starting over when more users arrive.
AI and automation built in
Automation of repetitive tasks and, when it helps, artificial intelligence. We evaluate it together and apply it only where it truly serves your operation.
Real-time dashboards and reporting
Control panels that show exactly the data that matters to your business. Interactive visualizations, filters, exports, and automatic alerts when something changes.
Integrations with APIs and third-party services
Connections to CRMs, ERPs, payment gateways, messaging services, logistics platforms, and any API your operation requires. All in one unified ecosystem.
Still running your business on spreadsheets and email?
That's where custom software comes in: it replaces the spreadsheets, the back-and-forth emails, and the manual work with a tool that does exactly what your operation needs. These are the most common project types. If yours isn't on the list, let's talk anyway; chances are it can be done.
- SaaS platforms with subscription billing
- Analytics dashboards and executive reporting
- Customer portals with authentication and role-based permissions
- Internal management systems (custom ERP, CRM)
- Integrations between services and workflow automation
- Applications with data processing and AI predictions
The right technology for your project
I choose each tool based on what your project needs: React, Next.js, Node.js, Python, Flutter, AWS, Azure, Docker, and whatever else it calls for.
Clear pricing, no surprises

What you might be wondering
When does it make sense to replace spreadsheets with custom software?
When several people use the same spreadsheet at once, when data gets copied from one place to another, when nobody knows which version is the right one, or when one wrong cell costs money. Custom software centralizes the information, validates data on entry, and automates the repetitive parts.
How much does custom software or a custom web application cost?
For businesses in the US, Europe, and other countries, a custom system or platform starts at $10,000 and a biometrics or anti-fraud project at $15,000. Before quoting I run a paid technical Discovery, from $900, covering scope, risks, architecture, and estimate. If you hire the project within 30 days, that amount is credited. The final price depends on users, roles, and integrations.
How long does it take to build a web app?
A custom system takes 12 weeks or more, delivered in phases: every 2 weeks you get a working version to review and approve. Projects with biometrics or integrations with your own systems usually take longer; the exact timeline comes out of the technical Discovery, before the budget is committed.
Can I integrate AI into my application?
Yes. I integrate AI models (OpenAI, Claude, Gemini) to automate tasks, generate content, classify data, or build conversational assistants inside your platform. AI goes where it makes real sense for your business, not where it makes a nice marketing bullet.
Do I own the source code when the project is done?
Completely. When the project is delivered, I transfer the full private repository with all the code, technical documentation, and access credentials. You don't depend on me to operate or modify your application.
What happens if my business grows and I need to scale the app?
The architecture is designed for scale from the start: separation of concerns, well-defined APIs, an optimized database. Adding new modules, increasing user capacity, or integrating new systems is part of the plan from day one, not a last-minute problem.
Have an idea that doesn't exist yet?
That's what the Discovery session is for: we talk for 5–8 minutes, I understand your project, and you get a clear technical and cost proposal.
