Where the curiosity started.
Portfolio / About
Useful software starts with understanding people.
I'm Hélder Cruz, a Software Engineer graduated in Computer Engineering from Universidade do Minho. I live in Braga (Portugal) and work in digital products that combine technical depth, thoughtful design and real-world usefulness.
From curiosity to engineering.
My interest in technology started through gaming. At first, it was curiosity: wanting to understand how the systems behind those experiences worked. Over time, that curiosity became a need to build things myself, understand software from the inside and use it to solve real problems.
02 ·Curiosity
Understanding how things worked became the real motivation.
03 ·Systems
That curiosity evolved into thinking about logic, structure and behaviour.
04 ·Software
Today, I use that mindset to build products for real people and real needs.
Real client work, real constraints.
Working with real clients taught me how to communicate technical decisions clearly, understand business needs and turn vague ideas into working software.
01
Casa Benfica Lenzburg
The most complete project I have worked on so far. What started as a public website became a broader digital ecosystem with event and album management, membership systems, reservations, email flows, work schedules, event agendas, editable cocktail menus and restaurant billing tools. Several internal operations now rely on software I designed and built from the ground up.

XV Studio
A website designed around the agency's services, with a specific visual direction for each area and a contact flow built to feel simple, guided and intentional.
03
HAUSB
A project where development and brand direction came together. Beyond building the website, I helped shape the digital identity, structure the message and create content for a field I had to study and understand.
How I approach software.
I like to start by understanding the purpose of the project, the people who will use it and the workflows it needs to support. Before writing code, I build a mental model of the product: what needs to exist, how the system should behave and how the user should move through it.
Human-driven functionality
Good software should consider human error, reduce unnecessary repetition and make important actions clear.
Design before execution
I usually think through the structure, flow and visual direction before moving into backend logic and frontend implementation.
Reliable systems
For me, software that works is software that handles edge cases, supports real workflows and remains dependable when real people use it.
Clear communication
Client work taught me how to explain technical decisions in simple terms and translate real needs into practical software.
What I care about.
Perfectionism, critical thinking and responsibility shape the way I work. I care about building things that are useful, not just visually impressive.
Responsibility
Owning decisions, respecting the people who depend on the work and keeping the product useful beyond the first delivery.
Critical thinking
Questioning assumptions, understanding trade-offs and choosing solutions for the real problem, not just the obvious one.
Attention to detail
Caring about the small interactions, edge cases and visual decisions that make software feel considered.
Beyond Code
Beyond code.
Outside software, I also compete as an esports athlete for Universidade do Minho, where I reached national podiums and became national champion in 2026. I also train MMA, play basketball and enjoy reading about psychology, sociology and human behaviour.
