Custom software to bring order to your operation.
Four years building software for banking and retail. I design and build internal systems for small businesses: appointments, records, inventory, reports or whatever your operation needs, in one place and built in stages.

What your system can solve
Every system starts from how your business works, not from a template. These are the problems I solve most often.
- 01
Appointments without clashes
Bookings that lock the time slot instantly, so two people can’t take the same one.
- 02
Records and histories
Everything about each client or patient in one place, with permissions based on who is looking.
- 03
Reports that build themselves
Reports that take days today come out of the system in seconds, ready to export to PDF.
- 04
Inventory, invoices and quotes
Track what comes in and goes out, and generate quotes and documents ready for the client.
- 05
Roles and permissions
Leadership, admin and staff see and do different things inside the same system.
- 06
Ongoing support and improvements
With the maintenance plan the system stays secure and keeps growing with you: security updates, bug fixes and changes.

An institute left spreadsheets behind and now sees its whole operation on one screen.
Students, schedules, attendance, transport and fuel lived in separate files. Each monthly report took days, and nobody fully trusted the numbers.

Practices that run without paper: appointments, records, prescriptions and billing in one place.
Small clinics used paper calendars and records in folders. Appointments overlapped, and finding a patient’s history ate minutes out of every visit.
How I work
A 30-minute call to understand your business and what you want to achieve. Free.
Scope, timeline and a fixed price in writing, within two or three days.
You see progress every week and pay against deliveries. At the end, the code is yours.
Price and payment
The final price depends on how many modules you need. We build it in stages: before we start I send you a proposal with the scope and a fixed price.

- Maintenance from US$ 50 a month: SEO follow-up, security and content changes
Maintenance: more than swapping a photo
After launch I stay in charge. Every month I make sure everything stays secure, fast and working, and I tell you what happened.
- 01
Security updates
Libraries and dependencies kept up to date, and the HTTPS certificate and domain watched so nothing expires or is left exposed.
- 02
Everything working
I check that it’s online, loads fast on a phone and that the form, WhatsApp and every feature keep responding.
- 03
Content changes
Text, photos, prices and products: you send them by WhatsApp or email and I publish them, without you learning any tool.
- 04
Improvements and priority support
Adjustments and new sections when your business needs them, and a priority response if something breaks.
Questions about custom software
How much does a custom system cost?+−
It starts at US$ 850 and depends on how many modules you need. We build it in stages: you pay against deliveries and start using each module as soon as it’s ready.
How long does it take?+−
From two months for a first working system. I deliver in stages, so you see progress every week.
Why not use off-the-shelf software?+−
Off-the-shelf software solves standard cases. When your process doesn’t fit its mold, you end up paying for features you don’t use and adapting yourself to the software. A custom system adapts to your business.
Who controls who sees each piece of information?+−
You do. Each person logs in with their own user and only sees what their role allows: leadership, admin or staff.
Who supports the system after launch?+−
I do, with the maintenance plan from US$ 50 a month: security updates, checks that everything works, bug fixes, changes and priority support. The system keeps growing with your business.
Tell me what you want to achieve.
