Our Technology Stack
How We Work with US Clients
Designed to feel like a local team — regardless of timezone.
Discovery & Scoping
30–60 min Zoom call to understand requirements. We document everything and send a detailed spec for your approval before quoting.
Fixed-Price Proposal
Clear scope, milestones, timeline, and USD price. NDA signed. You own all IP from day one — no ambiguity.
Agile Development
2-week sprints with Slack daily updates, GitHub access, and bi-weekly video calls. You see progress continuously, not just at the end.
Launch & Support
Full deployment, documentation handoff, and 60-day warranty period. Long-term maintenance packages available.
What working with an outside engineering team should feel like
Most US companies that have outsourced before have a story: missed deadlines, code nobody else can maintain, or a vendor who disappeared after launch. We work differently. You get senior engineers, a fixed price before work starts, a demo every week, and full ownership of the code from the first commit.
Your working hours, covered
Our day overlaps with US mornings, so stand-ups and calls happen in your time zone. Work continues while you sleep, and progress is waiting when you start your day.
Fixed price, in writing
A detailed scope and price before any work begins. If we underestimate, we absorb the cost. Payments are tied to delivered milestones.
You own everything
Code lives in your GitHub or GitLab from day one. Cloud accounts, domains and credentials are in your name. Nothing is held back at handover.
US-ready security and compliance
SOC 2-friendly engineering practices, HIPAA-aware architecture for health data, and contracts under clear terms with an NDA available before the first call.
Senior engineers, not juniors
The engineers on your discovery call are the ones who build your product. No bait-and-switch after the contract is signed.
Support after launch
A 60-day warranty on delivered work, then optional monthly maintenance from the same team that built it.
How it works
Discovery call
A free 30-minute call to understand your goals, users and constraints.
Scope and fixed quote
Within a week you receive a written scope, timeline and fixed price.
Weekly demos
Working software on a staging link every week, with your feedback built into the next sprint.
Launch and handover
Production deployment, documentation and a full transfer of everything to your team.
Web apps and SaaS MVPs typically cost $2,000–$8,000, mobile apps $3,000–$15,000, and complex enterprise systems from $8,000. No agency markup: you pay for engineering, not account managers.
Frequently asked questions
How do you handle the time difference?
We schedule overlap time during US mornings and use written daily updates. Most clients find the overnight progress a benefit rather than a problem.
What contract and payment terms do you use?
A fixed-price contract with milestone payments, usually 40% to start, 40% at the midpoint and 20% on delivery. We invoice in USD and accept ACH and wire transfer.
Who owns the intellectual property?
You do, in full. The contract assigns all IP to your company, and the code lives in your repositories from the start.
Can you work with our in-house team?
Yes. We regularly work alongside internal engineers, following your code standards, reviews and deployment process.
