Software studio — taking on new projects

Your product, built right and built to scale.

We design, build and run web, backend and cloud products for teams that can't afford to get it wrong. You bring the idea — we handle everything between it and your users.

  • Senior engineers on every project — no hand-offs to juniors.
  • A clear plan and honest timeline before we write a line of code.
  • One partner from first idea to production, support included.

how we work

From idea to launch, without surprises

Five clear steps, one accountable team. You see progress every week and know exactly where your project stands — from the first conversation to long after launch.

1

PLANNING

We analyze the requirements of your project, making sure we fully understand your needs, goals and constraints before a single line of code is written.

2

CODE IMPLEMENTATION

Our engineers turn the requirements into solid, efficient and well-tested code using modern, industry best practices.

3

TESTING & QA

Every change goes through automated tests and quality controls so your software ships flawlessly and stays reliable.

4

DEPLOYMENT

We set up your entire infrastructure — servers, pipelines and configuration — and ship to production with zero drama.

5

SUPPORT

We provide ongoing monitoring and support so your business keeps running smoothly long after launch.

the people

The team behind your project

No layers, no account managers in between — you talk directly to the engineers and designers building your product.

what we do

Everything your product needs, under one roof

Strategy, design, engineering and support — one team accountable for the whole result, so nothing falls between vendors.

project management for software development

Project management

One dedicated lead, weekly demos and a roadmap you can actually read. You always know what shipped, what’s next and what it costs.

UI UX design software development

UX/UI design

We research your users before we design for them. The result: interfaces people understand in seconds and keep coming back to.

technical support software development

Technical support

When something breaks at 2 a.m., we’re the ones awake. Monitoring, maintenance and fast response — long after launch day.

frontend design programming software development

Frontend design

Fast, polished interfaces that turn visitors into customers — built to feel instant on any device.

backend programming software development

Backend development

Secure, tested APIs and infrastructure that handle your busiest day as smoothly as your slowest — and grow with you.

packages

Custom software, fixed price

Software built around how your business actually works — not a template. Pick the scale, book a call, and know the price and timeline before we start. A small senior team: you talk directly to the people who build it.

our work

Portfolio

A look at what we build — client engagements, internal products and open source.

offline-first inventory and point of sale web application built by XSingularityInternal productOpen source

xinventory — inventory & point of sale

Point of sale for shops that price in dollars but get paid in bolívares. Prices are stored in USD and converted at a chosen reference rate, so a moving exchange rate never rewrites what a past sale earned. Reads fall back to a local cache and writes queue offline, because connectivity in a shop is not reliable.

inventory and ordering system for a hardware retailer built by XSingularityFerreAlianzaCase study

Inventory & ordering system

Catalogue and ordering for a hardware retailer. Administrators manage products by hand or by bulk Excel import; staff search the catalogue, build orders with discounts and tax, and export them to PDF, Excel or plain text for sending on.

real-time client project progress portal built by XSingularityInternal productOpen source

Client portal — live project progress

How our clients see their project instead of waiting for a status meeting: the portal reads the project repository and turns its issues into live progress bars — plain and time-weighted — plus a task list showing who is doing what and how long each task is estimated to take. Each client signs in and sees only their own projects.

AI customer service bot for Facebook Messenger that answers from a controlled knowledge base, built by XSingularityInternal productOpen source

Messenger FAQ bot — 24/7 customer replies

Answers customer questions on Facebook Messenger instantly, day and night, from a knowledge base the business controls. An LLM understands the question however it is phrased and paraphrases the official answer. Unknown questions queue in an admin panel; answer once and the bot handles that question forever after. Runs entirely on free tiers.

multiplatform Discord Telegram Slack and email assistant bot built in Go by XSingularityInternal productOpen source

SmarttyBot — multiplatform assistant

Relays messages between Discord, Telegram, Slack and email, and acts on plain language when addressed — running GitLab reports, sending mail, cross-posting. Messages that do not address it never reach the model, which keeps API usage down, and each platform enables itself only once configured.

native Android currency converter app for the Venezuelan bolivar built by XSingularityInternal productOpen source

XCambio — currency converter

Native Android converter for the Venezuelan bolívar. Switches between the official BCV rate, the P2P market rate, a blended average and a rate you enter yourself, and shows the live gap between the official and parallel markets. Each source is fetched independently, so one failing provider does not blank out the rest.
