I'm a senior mobile engineer and tech lead with a decade of shipping consumer apps that people actually keep on their home screen. I care about the craft that shows up between specs — the gesture that feels right, the empty state that earns a smile, the 80ms of latency nobody asked about but everyone feels.
These days I'm leading a mobile platform team at a Series B company, focused on rebuilding our rendering pipeline and mentoring the six engineers who touch it. I work remote from Lisbon, pair in the mornings, and write in the afternoons.
I keep a paper notebook next to my keyboard and fill one every four months. Half of it is diagrams, half is lists of things I don't understand yet. I think of engineering as a practice, not a performance — the good stuff compounds quietly.

I'm currently open to Tech Lead roles and a small number of freelance engagements per year — mostly consulting with early-stage teams on mobile architecture, performance, and the first year of hiring. If that overlaps with what you're building, I'd love to hear from you.
