The person behind App Tech Partner
Hi, I’m Daniel.
I am Daniel, a software engineer based in Lisbon. I help founders make deliberate technical decisions and turn mobile prototypes into products that can be released and maintained.
I work in mobile engineering today and take on a small number of independent founder projects outside my principal role. You speak directly with the person doing the technical work. We agree on scope and availability before anything begins.
My path
From learning to code in 2011 to shipping mobile products today.
Each stage shaped how I approach product decisions and engineering delivery today.
- 2011
I started learning to program
I began studying programming before entering professional software teams.
- 2013
Technical training in computing and web pages
I completed a technical computing course focused on building web pages.
- 2015
First software for a campus service
I built a PHP application for a student and staff health-assessment workflow, connecting forms, data and practical decisions.
- 2016–2019
Leading a junior software enterprise
As vice president and then CEO, I helped plan work, guide a team and deliver software for real needs.
- 2017
Research administration software
I developed a system to manage research-project submissions for a Brazilian campus.
- 2017
Hands-on computer support
A computer technician role added practical experience with the technology people use day to day.
- 2018–2019
Software for education at scale
I contributed to a distance-learning module adapted for the needs of 11 campuses, using PHP, JavaScript, PostgreSQL and Git.
- 2019–2020
First React Native product work
I began building mobile applications with React Native in sports and leisure, with later exposure to the commercial and marketing side of that business.
- 2020–2021
Mobile releases in compliance software
At a Brazilian provider of sustainability and legal-compliance software used across industries, I handled iOS and Android store work alongside React, Node.js, CI and microservice integrations.
- 2021–2022
Business software and complex interfaces
In a Brazilian engineering consultancy, I worked on a business-management platform and an application for exploring 3D point-cloud models, with TypeScript, React and Jest.
- 2022–2024
Frontend product work in Portugal
At a European technology consultancy, I continued developing web applications as a contracted frontend engineer in Lisbon.
- 2025–today
Mobile engineering in telecommunications
My principal role is mobile development for a large European telecommunications product. I offer selected independent work outside that role, with a defined scope and schedule.
What that experience covers
The app and the systems around it.
My work connects product behaviour, mobile code and the infrastructure a real release depends on.
- 01React Native and Expo
- 02iOS and Android releases
- 03Firebase, authentication and APIs
- 04Push notifications and deep links
- 05Analytics and product measurement
- 06Architecture and code review
How I work
Independent, selective and scheduled.
I maintain my current professional role. For independent work, I accept a limited number of projects with a clear outcome, planned work blocks and a direct handover. The first step is to describe the app and decide together whether the scope fits my availability.
