Modular methodology
How I build each module without stopping your business.
Instead of a blind, 12-month monolithic project, each area (invoicing, inventory, manufacturing…) goes through this 4-stage cycle. Once complete, the module goes live and delivers value right away, and the cycle repeats for the next block.
- 01 Assessment and data Milestone 01 · Assessment
Assessment and data
Rule mapping and secure link- Non-invasive discovery: I map the area’s processes and set up a secure, read-only link to your ERP or database.
- Fixed budget and scope: cost and timeline defined per module before any coding starts.
- Context preparation: I structure data and rules to speed up AI-assisted development.
Standard: Zero changes to your current systems.Gate01 Module scope and rules approved - 02 AI-assisted build Milestone 02 · Working software
AI-assisted development
Working software in weeks- Real software, not mockups: operational screens and processes built with AI assistance and reviewed by me, as the architect, before they reach your team.
- Private test environment: your team uses the module with real business data from day one.
- Live adjustments: I refine flows and validations with your immediate feedback.
Standard: Real, working modules without waiting months.Gate02 Working module validated by your team - 03 Audit and hardening Milestone 03 · Quality and security
Technical audit
Load and security testing- Expert review: architecture, concurrency and edge cases reviewed before touching production.
- Load testing: thousands of simulated transactions to handle peak days such as month-end closings or inventory counts.
- Security hardening: encryption in transit and at rest, role-based access and automatic backups.
Standard: Proven stability before going live.Gate03 Load and security tests passed - 04 Launch and expansion Milestone 04 · Production and cycle
Go-live and next cycle
No downtime and ready for the next module- Launch without plant downtime: deployed on DEV9 Cloud outside business hours, with backups and a rollback plan.
- Immediate return: the module is already running and saving time while I build the next one.
- Modular coupling: ready to connect to the next block of the plan.
Standard: A smooth transition, with close follow-up.Gate04 Module in production → next cycle starts
Cycle complete: the module runs live and the same cycle starts for the next module.

Experience
Senior-level experience, with direct contact.
I'm not an agency or a consultancy with layers of account managers: I'm an engineer who understands your operation, makes the architecture decisions and writes the code.
You talk to the person who builds it
Whoever hears your problem is the one who designs and codes the solution. No middlemen, nothing lost along the way.
I know operations from the inside
I have spent more than eight years leading IT in the manufacturing industry. I know the shop floor, month-end closing and piece-rate payroll, not just the code.
My own SaaS, on the market
I designed, built and run Tequitl, a platform with built-in AI. I know what it takes to keep a system running day after day, not just to build it.
Frequently asked questions
Before we start.
What clients usually ask me before starting a project. If you have another question, write to me.
Can't find your question?
I reply within 24 hours, directly.
Do I have to replace my ERP or current system?
No. The usual approach is to build around what you already have: I connect to your ERP or database and develop only what your standard system can’t handle, without altering its data.
How large are the projects you can take on?
From a module for a specific process to a complete platform for the whole operation. I work directly and independently, with no middlemen. A large project is split into modules that go live in stages, so the scope stays manageable and progress is measurable. Every module is documented and monitored, so the operation doesn’t depend on someone being available around the clock.
How long does it take and how much does it cost?
It depends on the scope. After the assessment you get a proposal with cost and timeline per module, and the first working module is usually in your team’s hands within weeks, not months.
Do I need to buy servers or infrastructure?
No. Your systems are hosted on DEV9 Cloud and I take care of deployment, updates, daily backups and monitoring, so you don’t need IT staff to maintain them.
Who owns the data?
Your company, 100%. Your information and databases belong to you, and you can export them whenever you need.
What support do you provide after delivery?
Bug fixes, adjustments and ongoing evolution of the system. We can agree on a maintenance plan with defined response times.
How do you use artificial intelligence?
In two ways. In development, I use AI assistants to speed up repetitive tasks, but the architecture, code review and testing are mine. In your product, I integrate AI as a feature when it adds value: agents, copilots or natural-language queries over your data.
Do you work with companies outside Mexico?
Yes. I work remotely with companies in Mexico, the United States and Latin America.
Next step Has your operation outgrown
Has your operation outgrown
spreadsheets and your current system?
Tell me how your company runs today. At no cost, I'll review what no longer keeps up (spreadsheets or the ERP you use), which manual tasks are worth automating and what to build first, connected to what you already have.
