I want a solution for my businessProjects in development
Help shape what comes next.
We are developing two applications of our own, guided by the same idea behind JG: making information more useful and everyday work simpler. Explore the projects and tell us what is missing.
Recruitment & teamsIn development
Aptalvo
More context to choose. More clarity to follow through.
An application to bring candidate information together, organise recruitment processes and support teams with structured information.
- Applications
- Selection
- Follow-through
- Organised information
- Comparison criteria
- Clear next steps
Explore the project
Who we are building for
Recruitment teams, agencies and businesses that need to track candidates and processes without scattering information across tools.
Where we are
The application is being developed and tested. We are preparing the conditions for a supported pilot. Decisions about candidates remain with the team.
Where in your recruitment process do you lose the most time or need better information?
Fictional data and simulated recommendations, with no AI connected. Do not enter real data.

Study & independenceIn development

An application connecting tests, study plans and homework, with progress tracking and a dedicated view for parents and guardians.
- Plan
- Study
- Follow progress
- Calendar and study plans

- Family involvement
Explore the project
Who we are building for
Students, parents and guardians. At this stage, we also welcome teachers’ and tutors’ views on study needs.
Where we are
A local version is being tested, including study organisation and a family view. Content and guided support are still being developed and require educational validation.
What would help organise study time and identify where support is needed?
Opens a message in your email application.
What would make a difference in your day?
A challenge, a missing feature or a specific suggestion. Your perspective can help us choose our next steps.
Eficiência Digital
Projects in development, not commercially launched. Features may change as testing progresses.
Share only your feedback. Do not send CVs, candidate details, student names or anyone else’s personal data.
Do these signs sound familiar?
There is a simpler way to work.
If your day depends on copying data, correcting errors, finding versions or building reports by hand, there is room to save time and work with more confidence.
Let us find that improvement01
The same work is repeated every week or every month.
02
The data exists, but it does not provide quick answers.
03
The file has grown so much that it is slow or difficult to maintain.
04
Your business needs a more professional online presence.
How I work
A clear process, from start to finish.
Understand
We start with the problem, the current process and the result you genuinely need to achieve.
Simplify
I design a solution that fits the challenge, without unnecessary complexity.
Deliver and refine
You receive a practical, tested and explained tool — with room for final adjustments.
My approach
Useful technology turns data into decisions.
I do not just deliver a file, chart or page. I seek to understand how the business works, what information it needs to see and how its data can support better-informed decisions.
- Simple, direct communication
- Solutions tailored to reality
- Focus on practical results
Frequently asked questions
Before we get started.
01Do you work on small projects?+
Yes. A project can be a targeted improvement to a file, a complete dashboard or a new website. What matters is having a specific problem to solve.
02Can you improve an existing file?+
Of course. I can assess the current structure, identify slow or fragile areas and propose improvements without forcing you to start again.
03Can we work entirely remotely?+
Yes. Requirements, reviews and delivery can all be handled remotely in a simple, organised way.
04How is the price determined?+
Once I understand the goal, current situation and deadline, I provide a clear proposal covering scope, deliverables and price.
Have a project in mind?
Which decision do you need to make with more confidence?
Briefly describe the challenge, the available data or the process you need to improve. I will help turn that information into a clear next step.
