Custom Software Development
Tailored web platforms, APIs and internal tools designed around your exact business workflows — not the other way round.
AI-Native Software Studio
Solid software for the AI era.
Macizo is Spanish for solid — and that's how we build. From custom platforms to LLM-powered agents with LangChain, we turn ambitious ideas into software that lasts.

What we do
Services built to move you forward
End-to-end engineering — from first prototype to production at scale.
AI & LLM Implementation
We integrate large language models — Claude, GPT and open-source — into your products: chat assistants, document intelligence, summarization and beyond.
Agentic AI with LangChain
Autonomous agents, RAG pipelines and tool-using workflows built on LangChain and LangGraph — grounded in your data, safe by design.
Cloud & DevOps
Scalable, secure infrastructure on AWS and Azure — containerized deployments, CI/CD pipelines and observability from day one.
Mobile Development
Native and cross-platform apps with Flutter and React Native — fast, polished and consistent across iOS and Android.
Data Engineering & Analytics
Pipelines, warehouses and dashboards that turn scattered data into decisions — and into fuel for your AI initiatives.
AI, done properly
From your data to real answers
Most AI demos break in production. Ours don't — because we engineer the full pipeline: ingestion, retrieval, guardrails, evaluation and monitoring.
-
RAG on your knowledge base — answers grounded in your documents, with citations.
-
LangChain & LangGraph agents — multi-step workflows that call your tools and APIs.
-
Model-agnostic architecture — swap between Claude, GPT or open-source models without rewrites.
-
Evaluation & guardrails — tested for accuracy, safety and cost before it ever meets a user.
How we work
A process as solid as the result
-
01
Discover
We dig into your goals, users and constraints — and define what success actually looks like.
-
02
Design
Architecture, UX and a delivery plan you can hold us to. No surprises later.
-
03
Build
Short iterations, working software every sprint, and honest demos throughout.
-
04
Scale
Launch, monitor, harden and grow — we stay with you well past day one.
Who we are
Engineers first, partners always
Macizo Technologies is a software studio with 15+ years of hands-on engineering behind it. We've shipped platforms for startups and established businesses alike — and in the last few years, we've gone deep on applied AI.
We stay deliberately small and senior. When you work with us, you work with the people actually writing the code — not an account manager relaying messages.
