Engineering meets business
Somazero is a senior software studio led by João Pereira — a hands-on technical leader who ships, and who thinks hard about why it matters to the business.
Why Somazero
Somazero began as João's independent practice and grew into a studio. Soma is Portuguese for sum. The name is a small joke and a real principle: good engineering is about what adds up, and what nets to zero surprises.
Today we sell focused software services — backend, data and AI — to teams who need senior firepower and a calmer, more predictable delivery process.
13+ years of shipping
We have built across fintech, crypto, logistics and gaming — transaction engines, crypto-data ETL pipelines, automatic bidding systems and self-serve payment flows. Along the way we've led teams, run hiring, and set technical direction.
We stay hands-on and bring in vetted senior collaborators to scale a project's capacity — so you get senior judgment on every engagement, without the overhead of a big agency.
An engineer who speaks business
João is completing an Executive MBA at Porto Business School — not to leave engineering, but to be sharper at what founders actually care about: turning engineering into outcomes, managing risk, and making technical decisions that move the business.
How we think about the work
Tests are the spec
If it matters, it has a test. The suite is how we move fast without fear.
Small batches, shipped
Frequent, reviewable releases beat big-bang merges every time.
Security isn't optional
Least privilege and threat-awareness from the first commit, not the last.
Outcomes over output
Lines of code are a cost. Shipped value is the point.
