Does this sound familiar?
Missed deadlines
Your previous agency delivered 3 months late, with no explanation.
Budget overruns
"Technical surprises" keep piling up and the final invoice is double the quote.
Spaghetti code
Your app is so hard to maintain that every new feature costs a fortune.
No transparency
The agency speaks in jargon and you have no idea what's actually happening.
Our approach changes everything
2-week sprints. Continuous validation. Zero surprises.
UI/UX Design & Figma Prototype
You see and approve every screen before a single line of code is written. No bad surprises.
High-performance Next.js / React
Modern, fast, scalable stack. Your product loads in under a second and handles the load.
Robust backend & API
Solid, secure, documented architecture. Your product can evolve without rebuilding everything.
Auth, payments & security
Stripe, Auth0, Supabase — properly integrated from day one for a production-ready product.
Cloud deployment & CI/CD
Automated pipeline. Every update is tested and deployed without service interruption.
Technical SEO & Core Web Vitals
Your product is visible from launch. Lighthouse score > 90 guaranteed.
How does it work?
Audit & Scoping (Week 1)
We spend 1h together understanding your business, your users and your goals. We leave with a precise brief and a fixed budget.
Design & Prototype (Weeks 2–3)
Our designers create Figma mockups. You approve each page before we write a line of code. Unlimited revisions at this stage.
Development in sprints (Weeks 4–8)
Deliveries every 2 weeks. You test, give feedback, we iterate. You see your product take shape in real time.
Tests, launch & handover (Week 8+)
Load tests, security audit, production launch. Team training and complete documentation provided.
