Scaling your team shouldn't slow your product down.
Hiring takes months. Onboarding takes weeks. One wrong hire sets your team back even further.
tre plus adds senior developers from Kosovo who fit your engineering culture and contribute from day one.
No recruitment overhead. No ramp-up delays. Just people who work the way your team does.
No commitment. Just a quick intro.
Why scaling feels harder than it should
You know the pattern. Your backlog grows faster than your team. Every option you try adds overhead instead of velocity.
Hiring takes months, and your best candidates drop off halfway through.
Onboarding slows your senior engineers down. They're mentoring instead of building.
Freelancers fill gaps but don't integrate. They leave when the project ends.
Offshore teams need constant hand-holding. You spend more time managing than shipping.
Developers who work the way your team does
Every developer at tre plus has at least 4 years of hands-on experience. We select on technical depth, problem-solving and communication, not just stack keywords.
Works as part of your team
Your developer joins your stand-ups, follows your branching strategy and participates in architecture discussions. It feels like a colleague joined.
Product-fit matching
We match on product context, not just tech stack. Your developer understands your roadmap and asks why before they build.
Contributes from day one
No three-month ramp-up. Your developer follows your definition of done and writes code that passes your reviews from the start.
Long-term ownership
No rotation, no sharing. Your developer grows with your product and takes ownership of their domain.
