[ 01 — what we do ]
Three disciplines,
one delivery team.
Most products need a polished app, a solid server and somewhere to run it. We cover all three so the pieces fit together from day one.
Backend
Secure, scalable services with decades of enterprise experience behind them. Performance, security and clean APIs come standard.
Cloud
Move the heavy lifting to the cloud and scale on demand, without buying and babysitting your own expensive infrastructure.
Engineering & training
Workshops and hands-on coaching across the whole software lifecycle: version control, test-driven development, continuous integration and pragmatic SDLC.
[ 02 — how we work ]
The benefits of a team,
the focus of a freelancer.
01
Single point of contact
You talk to one person. We handle the coordination between disciplines internally, so communication overhead stays low.
02
Complementary skills
iOS and Android, Swift and Kotlin, backend and cloud. The right specialist on each part instead of one generalist stretched thin.
03
Senior by default
No juniors learning on your budget. Everyone has shipped production software for demanding clients across many industries.
04
Transparent & on time
You're a stakeholder from start to finish. Straightforward process, honest estimates and a commitment to prompt delivery.
[ 03 — the toolbox ]
A stack we know cold.
Proven, boring-in-the-good-way technology, chosen to fit the problem rather than the hype cycle.

[ 04 — the collective ]
Independent engineers who like working together.
Brainjumps is a group of freelance software developers bound by a passion for building things well. Because our skill sets are complementary, we can take on multi-platform projects and deliver as one team.
We can build your product on iOS and Android at the same time, port an existing app to a new platform, or stand up the backend that ties it all together. The team is a well-oiled machine, so you get team velocity without the team overhead.
Work with usBuilt with careWe feel responsible for what we ship and stand behind it.
CreativeOut-of-the-box thinking for the trickier problems.
EfficientA close-knit team means minimal managerial overhead.
SupportiveQuick to respond long after the app goes live.
