01 What we do
From product to production.
We are a software engineering team. We take a business problem and turn it into a system that works, scales, and that your team can rely on every day.
Web and mobile apps
Fast, accessible and consistent interfaces on any screen, backed by a robust backend.
- Web apps and PWAs
- iOS and Android apps
- Websites and content platforms
Platforms and internal systems
Software that organises your operations: back-offices, customer portals and tools shaped around the way your company works.
- Back-offices and customer areas
- Approval and management workflows
- Reports and dashboards
APIs and integrations
We connect the systems you already use so information flows without manual copying or duplicated data.
- REST and GraphQL APIs
- ERP, CRM, payments and social networks
- Webhooks, queues and sync
Applied AI and automation
Artificial intelligence built into software and processes, with concrete goals, clear rules and people deciding what matters.
- Context-aware assistants and agents
- Search over documents (RAG)
- Automation of repetitive work
Cloud, DevOps and infrastructure
Production-ready infrastructure: automated, monitored and with costs under control.
- Containers and continuous deployment
- Monitoring and alerting
- Backups and recovery
Legacy modernisation
We evolve older software without stopping the business: gradual migration, piece-by-piece rewrites and managed technical debt.
- Code and architecture audits
- Data and stack migrations
- Performance improvements
Product design and UX
Before the code, understand who will use it. We design simple flows and interfaces, tested with real users.
- Product discovery and definition
- Clickable prototypes
- Design systems
Maintenance and evolution
After launch we stay by your side: fixes, security updates and new features.
- Ongoing support
- Updates and security
- A team dedicated to your product
02 Expertise
Building software is what we do best.
Working on launch day is not enough. The software we deliver has to keep working as the business grows, as the team changes and as new needs appear.
/01
Architecture designed to grow
We design modular systems with clear boundaries, so adding features never means rewriting what already exists.
/02
Quality that is verified, not promised
Typed code, peer review, automated tests and static analysis on every change. Problems surface before they reach your users.
/03
Data and performance
Careful data modelling, optimised queries and caching where it matters. Fast systems with thousands or millions of records.
/04
Security and privacy from day one
Robust authentication, role-based permissions, encrypted data and GDPR-aligned practices. Security is part of the design, not a patch.
/05
Continuous delivery
Automated integration and deployment pipelines, staging environments and frequent, small, reversible releases.
/06
Down-to-earth AI
We use language models where they bring measurable value: with business context, defined limits, tracked costs and human review on the right decisions.
/07
Documentation and independence
We document decisions, architecture and operations. If you ever want to bring the project in-house, your team can carry on without depending on us.
03 How we work
Short steps. Informed decisions.
Every project starts by understanding what really needs to be built. Then we move in stages, with visible deliverables and room to adjust course.
01
Understand the problem
We talk to the people who decide and the people who will use it. We map requirements, constraints, existing systems and what success looks like.
Scope, priorities and estimate
02
Design the solution
We define architecture, data model, integrations and user flows. We validate with prototypes before investing in code.
Validated architecture and prototype
03
Build in short cycles
We develop in one- to two-week iterations, with regular demos and access to the staging environment at all times.
Working software, every cycle
04
Launch and evolve
We go to production with monitoring in place, follow real usage and keep improving based on data.
Live product, always improving
Serious software.
Long-term relationships.
Gatle is a Portuguese software engineering company. We work with a small number of clients at a time, so every project gets the attention it deserves.
04 How we behave
What you can expect from us.
/G
Every project is a vote of confidence
When someone hands us a problem, they trust us with part of their business. We recognise that and treat the work with the care it deserves.
/A
A high bar
We are not satisfied with what merely works. We look for the right solution, keep learning and deliver work we are proud of.
/T
No surprises
Honest estimates, visible progress, access to the code and environments. When something goes wrong, you hear it from us first.
/L
On your side, for the long run
The code and intellectual property are yours. We look after your interests, even when that means recommending doing less.
/E
Thinking about who uses it
We put ourselves in the shoes of your users and your team. Good software makes someone's day simpler.
05 FAQ
Before we start.
Short answers to the questions we hear most often. For anything else, drop us a line.
What kind of projects do you take on?
SaaS products, web and mobile apps, internal platforms, system integrations and AI-powered solutions. We work with startups building their first product and with companies that need custom software for their operations.
Who owns the code?
You do. The code, documentation and intellectual property belong to the client. Whenever possible we work in your repositories and your cloud accounts, so you are in full control from day one.
How much does it cost and how long does it take?
It depends on the scope. After a first conversation we prepare a proposal with clear phases, timelines and costs. We prefer to start with a well-defined first version and grow from there, rather than budgeting everything at once.
Can you take over an existing project?
Yes. We start with an audit of the code, architecture and infrastructure. The result is an honest assessment and a plan: stabilise, improve piece by piece or, when it truly makes sense, rewrite.
What happens after launch?
We remain available for maintenance, fixes, security updates and product evolution. We can also prepare a handover to an in-house team, with documentation and support.
How do you handle data when using AI?
We choose providers and settings that do not use your data to train models, restrict access to what is strictly necessary and log what the system does. Privacy and GDPR are part of the solution design.
Do you work with companies outside Portugal?
Yes. We work in English and Portuguese, remotely, with in-person meetings when they make sense.
06 Contact
Shall we build something together?
Tell us what you need: an idea, a system that no longer fits or a process that should be automatic. We will reply with concrete questions and a proposal for next steps.
