// About me
Who am I?
Since I can remember, I've always had a curious mind. From the days I tried fixing my first console's controllers at age 7, to learning how to recover my computer after breaking it at 15, technology has always fascinated me.
In 2006, I joined the Portuguese Air Force as an IT Systems Administrator. Later, I transitioned to the GNR's territorial service and subsequently joined UEPS, being part of heli-transported first-response teams fighting rural fires. In 2022, I decided to dive into the world of programming.
I believe that, with commitment and consistency, it's possible to achieve any goal. I see myself as someone in constant evolution, always adapting, looking forward, and improving day by day.

// Services
Clear services.Transparent pricing.Built for modern digital products.
I help startups and businesses launch websites, web apps, mobile apps, and AI features with a practical, product-focused approach. Every service is structured around outcomes, timelines, and realistic starting prices.
The prices below are starting points for typical projects. The final value depends on the scope, integrations, timelines, and product complexity.
Landing Pages & Websites
Fast and modern websites, built to clearly present your business and convert visitors into leads.
Ideal for businesses that need a strong online presence, a product landing page, or a professional institutional website. I design and develop responsive websites with clean front-end implementation, clear content structure, and the technical foundations needed for a quick launch.
- Responsive marketing website or landing page
- Implementation based on HTML, CSS, JavaScript or React
- Conversion-focused page structure
- Contact forms and lead capture
- Basic SEO and performance optimization
- Analytics and third-party integrations, if needed
Ideal for simple business websites, campaign pages, and product landing pages.
Web Apps & MVPs
Custom web applications for startups and teams that need to launch, validate, or optimize operations.
Ideal for founders and businesses that need more than a website. I develop modern web apps using React, TypeScript, Next.js, and Supabase, focusing on speed, maintainability, and practical product delivery.
- Product MVPs and internal tools
- Dashboards, portals, and admin panels
- Authentication and user roles
- Database architecture
- API integrations and third-party services
- Deployment setup and launch support
Suitable for SaaS MVPs, client portals, internal platforms, and operational tools.
Mobile Apps
Cross-platform mobile applications for iOS and Android with a focus on speed, usability, and scalability.
Ideal for businesses that need a mobile product without the need to build separate native teams. I develop mobile apps using the latest technologies, helping clients launch practical applications faster.
- React Native app development
- Delivery for iOS and Android from a single codebase
- Authentication and backend integration
- API, Supabase, and real-time features
- Push notifications and common app flows
- Store launch support and iteration guidance
Indicated for MVP apps, operational applications, booking flows, member apps, and customer-oriented mobile products.
AI Features & Automation
Practical AI integrations that solve real business problems, instead of just following trends without added value.
Ideal for teams that want to use AI in a focused and useful way. I help design and implement AI-based features, such as chatbots, internal assistants, LLM workflows, document-based search, and support automation, choosing the right tools for each use case.
- AI discovery and solution design
- Chatbots and assistant workflows
- LLM integration and orchestration
- Document search, retrieval, and prompt workflows
- Automation for support and internal operations
- Guidance on model choice, trade-offs, and implementation
Best delivered in phases: discovery first, then implementation, and optimization after launch.

For clients who need continuous improvements, support, maintenance, or product iteration after launch.
Basic Plan
From 360 €/year- Bug fixes and minor updates
- Basic maintenance support
- Priority handling for minor requests
Recurring Support
From 800 €/year- Continuous improvements

Need a website, app, or AI feature built with clarity from day one?
If you already have an idea, I can help turn it into a practical product with a defined scope, realistic pricing, and a modern technology stack.
frequently asked questions
Frequently Asked Questions
Everything you need to know before reaching out.
Services & Pricing
For clearly defined work, I usually recommend project-based pricing. For ongoing, evolving, or less defined work, monthly retainers or hourly rates may be a better fit.
No. They are starting points based on common project scopes. Final pricing depends on features, integrations, complexity, content readiness, and timeline.
I mainly build with HTML, CSS, JavaScript, React, TypeScript, Next.js, Supabase, and React Native. I also work with AI integrations, chatbots, and LLM-based product features.
Yes. If the scope is not yet clear, we can start with a short discovery phase to define requirements, technical direction, and delivery priorities before implementation.
Yes. I work remotely and can support clients anywhere in the world.
Yes. I offer ongoing support, iteration, and maintenance through monthly retainers for clients who need continuous improvements after the initial release.
Hosting & Maintenance
No. The website project only covers design, development, setup, and launch. Hosting, domain registration, and ongoing support are billed separately. Even without a maintenance plan, there will always be recurring costs for hosting and annual domain renewal, totaling 10€ per month.
Not always, but it is recommended. A maintenance plan helps keep the website online, updated, secure, and supported after delivery.
Hosting keeps the website online. Maintenance covers technical upkeep, monitoring, updates, backups, and support after launch.
Domain registration is usually billed separately and renewed annually. I can help set it up and manage it, but ownership should remain with the client.
Yes. If you already have a hosting provider or want full control of the infrastructure, I can deploy the website there and provide support separately.
No. Content changes are only included in selected plans. Simple infrastructure or basic maintenance plans do not include ongoing content edits unless agreed separately.
Small updates usually include text changes, image replacements, button label updates, or minor layout adjustments within the existing design. New pages, redesigns, and new functionality are not considered small updates.
Any extra work is quoted separately, either as hourly work or as a fixed-price mini project, depending on the size and complexity of the request.
Usually, no. The included monthly time is reserved for that billing period unless a different agreement is explicitly made.
The client should own the domain and any third-party accounts whenever possible. The delivered website is built for the client, while ongoing hosting and support can be managed either by the client or through my service.
