Personal product studio
QuietStackLabs
Useful software for quieter, more intentional lives.
Independent product practice by José Queiroz.
Casa da Piedade
A bilingual editorial and hospitality website for the Casa de Nossa Senhora da Piedade in Ponte de Lima. It brings together five centuries of family history, classified architecture, accommodation, a living archive, and ongoing preservation projects without reducing the place to a booking page.
- My role
- Content architecture, interface design, and development
- Defining decision
- Build one bilingual system for history, stays, preservation projects, and editorial publishing.
Petricor
An image-led portfolio for a woodworking practice where material, joinery, and process carry more weight than sales chrome. The site gives custom furniture and functional objects room to breathe, while a structured work catalogue makes projects easy to explore and maintain.
- My role
- Art direction, information architecture, design, and development
- Defining decision
- Let the material lead, then structure every object as a maintainable project record.
NightShelf
A swipe-first place to discover, save, and track films, series, anime, and books. NightShelf separates the lightness of discovery from the commitment of a personal library, then brings progress, ratings, and meaningful recommendations back around what the person chose.
- My role
- Product strategy, interaction design, full-stack, and mobile development
- Defining decision
- A swipe saves to Queue first; moving something into the Library remains a deliberate second step.
Weekline
A work journal built around the week rather than an endless task list. Focus sessions become a readable weekly record, with project context, self-review, visual summaries, and a clear view of what actually moved.
- My role
- Product design, interaction design, and full-stack development
- Defining decision
- Make every focus session part of a weekly record that can be reviewed, copied, or exported.
Férias BV
A full property-management workspace for the daily reality behind short stays: occupancy, revenue, costs, arrivals, departures, guests, and multiple properties. A lane-packed calendar keeps overlapping bookings legible, while live pricing, status, and notes stay close to each reservation.
- My role
- Product strategy, operational modelling, design, and development
- Defining decision
- Put status, season-aware pricing, guests, and costs around one legible booking calendar.
Downloads Organizer
A menu-bar utility that watches local folders and applies ordered rules to rename and move finished downloads. It starts in dry-run, ignores incomplete files, records every real action, and makes it undoable — with multi-folder support, reusable presets, rule previews, and local-only processing.
- My role
- Product strategy, native macOS design, and Swift engineering
- Defining decision
- Preview first, wait for completed files, and make every real move visible and undoable.
Local files.Reversible actions.
My5
A private emotional network for up to five trusted adults. Share one feeling with your circle or reach one person directly; they can answer with a bounded voice note, image, or short video — no public profiles, feed, followers, popularity metrics, or emotional-data advertising.
- My role
- Product strategy, trust model, mobile design, and engineering
- Defining decision
- No chat or feed: one feeling, one bounded response, then the private moment disappears.
A studio name for one person.
One person who makes the whole thing.
I’m José Queiroz, an independent product designer and engineer. Quiet Stack Labs is where I turn stubborn problems into thoughtful, useful software.
I move from the problem and product model through interface, motion, implementation, and launch. That continuity is the point: clear decisions and a product that still feels like one idea.
Have a problem worth
getting close to?
Tell me what you’re building, where it feels stuck, and what a good outcome would look like. I work directly across product thinking, design, and implementation.
