Sound familiar?
Excel and off-the-shelf software make you work twice as hard
Spreadsheets that overwrite each other, data entered twice and generic systems that don't fit your business. Your team is surely losing hours every day on tasks a system can do on its own: often, more than half of the office work.
Does any of this happen to you?
- You enter the same data in several spreadsheets and never know which one is up to date.
- To know how much you sold or what stock you have, you have to ask around or wait until the end of the month.
- You spend hours copying data, building reports and checking payments by hand.
- Your system is off-the-shelf: it doesn't adapt to your business, you adapt to it.
- Your website goes down, is outdated or doesn't show your real stock.
- Someone without experience promised you everything without knowing your business, and the project dragged on or cost twice as much.
- Whoever built your system kept the passwords, and now you depend on them for everything.

15 years of experience
I've built software for SMBs and large companies for 15 years. Before promising anything, I understand your business, the scope and what it really costs.
Your system is yours
It runs on your server or on hosting in your name, and when the project ends, the code is yours. For your peace of mind, we sign a confidentiality agreement.
Full transparency
I work in the open: passwords and access are in your name, and you know what's being done and why at every step. The keys to your system are always yours.
How many hours a week go into spreadsheets? Tell me how you work today and I'll show you what can be automated.

Security and privacy
Your data, truly protected
Cybersecurity is my specialty: every system is designed to protect your information and your customers' from day one, following international standards and up-to-date protocols.
Privacy by design
Each system stores only the data it needs, and each person sees only what their role allows.
Personal data
Systems designed to comply with Argentina's Personal Data Protection Law (25,326) and, if you work internationally, the EU's GDPR.
International standards
Best practices based on ISO/IEC 27001 for security management and on the OWASP guidelines for secure software development.
Up-to-date protocols
Encrypted connections, two-factor authentication, an audit trail of every action and constant security updates: nothing falls out of date.
- Encrypted connections (HTTPS)
- Securely stored passwords
- Two-factor authentication
- Role-based permissions
- Audit trail of every action
- Automatic off-site backups
- Security updates
- Confidentiality agreements
Already have systems and not sure how secure they are? I review access, passwords, backups and updates, and leave you a prioritized action plan.

How I work
From idea to system, no runaround
A simple, transparent process: you always know what stage your project is at.
Step 1
I listen
Tell me your idea in your own words. I'll help you organize it and put it into words.
Step 2
I propose
I show you what can be done, in which stages and how much it costs. There's always an option for your budget.
Step 3
I build
We move forward in stages: you see and try real results from the first weeks.
Step 4
I support you
I train your team, leave you manuals and stay by your side to keep improving.
Every system includes
Role-based training
For each person according to their access level and what they do in the system.
Manuals
Digital and printed, written to be understood.
Direct support
I answer the phone. You talk to the person who built your system.
Security and backups
Per-user access and responsible backups.
Continuous improvement
The system grows with your business; it never gets frozen.
Why NRE
Your idea is valid. There is always a way to make it happen.
I know that "IT" often feels like a wall: people who don't pick up the phone, who speak in jargon or just charge a lot. I work exactly the other way around: with empathy, truly listening and finding the way to make your project happen.

Nicolás Erriquenz
Founder · developer and technology teacher
I've been writing software for small businesses and large companies for 15 years, and today I also run the infrastructure and IT security of a company. I'm involved in every project from start to finish: from understanding your business to training your team and supporting you after delivery.
Never a "can't be done"
Every need has a solution. Together we find the approach that fits you best.
I answer the phone
You talk directly to the person who builds your system. No walls, no tickets that get lost.
I help you explain your idea
You don't need to know about technology: I help you put what you need into words so we can build it.
A budget for everyone
Small or large projects: there's always a proposal that fits what you can invest.
Frequently asked questions
Ask away
There are no silly questions or small projects. If you don't find yours, write to me: I'll answer personally.
Ask my questionI get by with Excel today, why change?
Excel is great to get started, but as your business grows it fills up with spreadsheets, errors and manual work. A custom system keeps what works for you and automates the rest: fewer hours entering data and more time for your business.
We already pay for off-the-shelf software. What do we gain with a custom one?
A system that adapts to your business, not the other way around: it automates your real tasks, connects to your website and your phone, and grows with you. And we move your information to the new system, without starting from scratch.
Is the system in my name?
Yes. It runs on your server or on hosting in your name, when the project ends the code is yours, and all passwords and access belong to you. For your peace of mind, we sign a confidentiality agreement.
Do you work with clients outside Argentina?
Yes. I work remotely with clients in other countries: we meet by video call, I schedule key meetings in your time zone and I quote in US dollars.
Isn't my project too small?
No project is too small. If it solves a problem, it's worth talking about: many big systems started as a spreadsheet.
I'm not sure how to explain what I need. Can I still ask?
Of course. That's the first part of my job: I ask you questions, show you examples and together we shape the idea.
How much does it cost?
It depends on what you need, and there's always an option. The first call is free, and then I send you a clear quote, in stages, with no surprises.
What happens after delivery?
I train you and your team according to each person's role, leave you digital and printed manuals, and we stay in touch for support and improvements.
Do you offer standalone consulting or training?
Yes. IT consulting by the hour or with a monthly retainer, and training in artificial intelligence, programming, cybersecurity, Excel, Word and more.
Do you work with large companies?
Yes: from startups to companies with their own servers, multiple locations or distributed teams. I sign confidentiality agreements whenever needed.
I already have an old system. Can it be modernized?
Yes, without losing your information. I've migrated systems built in Visual FoxPro and Visual Basic, and databases with hundreds of thousands of records.
