Custom software engineering, remote, since 2018

We build the software that other companies run on.

Inventory, sales, invoicing, traceability, dashboards and automation systems — plus whatever else you need built to fit. Designed for your team to take over, understand and extend for years.

  • 40+ products in production
  • 99.9% sustained uptime

Don't see yours? Distribution, food, services: what our clients have in common isn't the sector — it's an operation that cannot stop for a day. Tell us about yours.

When the operation outgrows the tools.

If any of this sounds familiar, the problem is rarely a missing tool. It's that the software you have wasn't built for how you work.

  • Critical processes still running on spreadsheets, scattered messages and manual work.
  • Old or isolated systems that duplicate data and slow the team down.
  • Off-the-shelf software that forces the company to work the way the product wants.
  • No visibility or traceability to grow without losing control.

What we've already built.

Projects we've delivered. Several are under NDA, so we describe the work and the sector without naming the company.

Health and pharmacy

Point of sale, batch-and-expiry warehouse, supplier purchasing and patient records — with the therapeutic indication catalogue wired to stock, so the doctor prescribes what is actually on the shelf.

  • Angular
  • Node.js
  • Express
  • MongoDB

Our own product · SaaS

Multilingual training platform with subscriptions, simulated tables and an affiliate programme. We built it, we run it, and we have maintained it since 2023.

  • Angular SSR
  • Node.js
  • MongoDB
  • Stripe
  • PWA

Territorial operations

Crew coordination system with a mobile app, location-stamped capture and a live progress board — running in single-day operations, where there is no second chance.

  • Node.js
  • Express
  • MongoDB
  • NativeScript
  • AWS

Energy distribution

Account, usage and payment lookups without calling a support line. Angular front-end over the utility's existing services.

  • Angular
  • TypeScript
  • Internal systems integration

Mobile telecom

Mass participation for a national campaign, sized for traffic peaks concentrated into a few hours.

  • High-traffic web
  • Carrier platform integration

Specialist breeder

Photo-and-video catalogue the client administers themselves, an admin panel, and automatic social posting the moment a listing goes live.

  • Next.js
  • React
  • Supabase
  • Facebook Graph API

Public statistics

Capture and lookup for information-gathering campaigns, with in-form validation and progress tracking.

  • Angular
  • TypeScript

Municipal government

Seven years of crime data turned into trends by offence type, so security decisions rest on evidence instead of perception.

  • Data analysis
  • Python

Specialist retail

Public catalogue with stock and sale-status administration, plus the backend that feeds it.

  • Angular
  • Express
  • MongoDB

Education and employment

In progress

A platform where training stays free until the candidate lands a job, with exam-based assessment that shows where each person needs reinforcing.

  • Next.js
  • TypeScript

And yours — what would it cost?

Answer seven to eleven questions and we give you a range in Mexican pesos, the technology that best solves what you described, and what moves that number. It is orientative, not a quote — and it does not cost you a call.

Systems designed for real operations.

Examples of the systems we design. Scope, architecture and integrations get defined against your operation — not picked off a menu.

Operational systems

We design the administrative and operational system around the processes your company already has: what gets bought, what gets sold, what sits in the warehouse, what gets billed.

  • Inventory and warehouse
  • Sales and customer tracking
  • Integrated electronic invoicing

Digital platforms

We build web and mobile applications, self-service portals and corporate sites wired into the operation — not separate pieces somebody has to reconcile by hand.

  • Self-service portals
  • Web and mobile applications
  • Corporate sites

Automation and integration

We connect the systems you already run and take out the repetitive work, through APIs, tax integrations, business rules and messaging channels.

  • Integrations and APIs
  • Process automation
  • WhatsApp and chat support

Data and intelligence

We organize the information your operation already generates and turn it into metrics, dashboards and decision support.

  • Metric dashboards
  • Reporting and traceability
  • Models and AI support

What if what you need isn't on that list?

The systems above are built from these capabilities — the same ones we use to stand up anything that isn't on the list.

Custom development

From discovery to launch. We build the whole product — not a prototype someone else has to rebuild.

Legacy system modernization

We migrate critical systems in stages, with a rollback path at every step. Your business doesn't stop.

Architecture and infrastructure

We design the foundation everything runs on. Scalable when it has to be, simple until then.

Integrations and APIs

We connect the systems you already run so they stop ignoring each other.

Data and AI

We turn the data you already generate into decisions you can defend to your board.

Security and compliance

Audits, hardening, and support to reach the standards your industry demands.

How we work, in practice.

We understand

Before we propose anything, we listen to the business problem and look at what's already running.

We design

We define scope, architecture and success criteria in writing. Nobody signs a vague document.

We build

Frequent releases you can see working. You get real progress every week, not a report full of percentages.

We hand off

We transfer what we know and stay on for support. The goal is for your team to stop needing us.

Why we exist, and where we're going.

Our mission

Technology shouldn't be what blocks a company that wants to grow. We build systems people understand, your team can maintain, and nobody has to start over every three years.

Radical clarity

We write and talk to be understood. Sounding smart is someone else's goal. If we can't explain it, we probably don't understand it yet.

Software that lasts

We optimize for whoever maintains the code three years from now. Tomorrow's demo comes second. Boring and proven beats new and fragile.

Transparency with clients

If we're running late or we got something wrong, you'll know before you ask. Bad news is a lot cheaper early.

Sustainable pace

We don't reward all-nighters. We reward shipping well, at a pace that holds next week and the week after. Projects that depend on heroes are the ones that fall over when the hero leaves.

Ready to start?

Tell us what you're trying to solve. You'll get a straight proposal with a realistic estimate range — not a generic catalog.

Wherever your team sits, we work on your hours. We're in Mexico City — Central Time. Distance doesn't change how we deliver: same reviews, same demos, same post-launch support.
