Your Application,
Not Your Problem
From idea to working product. We build MVPs, PWAs, dashboards and SaaS
on a stack that scales: Next.js + Supabase + Vercel.
What We Build
We do not do "everything". We specialise in specific kinds of applications.
MVP / Prototype
Validate your idea in 4-6 weeks. Core features, real users, real data. Not a wireframe — a working product.
PWA (Progressive Web App)
One app — phone, tablet, desktop. Offline mode, push notifications, install prompt.
Dashboard / Panel
Admin panels, KPI dashboards, CRMs. Real-time data, role-based access.
API Integrations
We connect systems: Stripe, Meta, Google, CRM, ERP, custom APIs. Webhooks, sync, automation.
AI Features
LLM chatbots, content generation, data analysis, recommendation engines. GPT-4, Gemini, Claude.
SaaS / Platform
Multi-tenant, Stripe billing, user management, onboarding. From zero to recurring revenue.
Before and After
See how we turn messy processes into professional tools.
Before: Excel + Manual Work
- • Data scattered across 5 different spreadsheets — nobody knows which one is current
- • Copy-paste between sheets — errors on every transfer
- • No access control — everyone sees everything
- • Reports created manually every Monday — 3 hours of work
- • Zero automation — email notifications handled manually
After: Your Web App
- • Single source of truth — real-time dashboard with always up-to-date data
- • Automatic import — API sync, zero copy-paste
- • Role-based access — admins see everything, users only their own data
- • Auto reports — generated every Monday at 8:00, zero manual work
- • Webhooks + email — automated notifications in seconds
Result: Clients save an average of 12 hours per week after moving from spreadsheets to a custom app. Errors drop by 95%.
This Is What
Not mockups — real production applications serving users every day.
Dashboard & Panel Administracyjny
Real-time KPI, wykresy, tabele danych. Role-based access, filtry, eksport do CSV.
PWA — Jak Natywna Aplikacja
Install from the browser, push notifications, offline mode. One codebase, every device.

Our Stack
What We DON'T Use
- • WordPress / PHP — slow, vulnerable to attacks
- • jQuery — 2010 technology
- • Shared hosting — slow, unscalable
- • Bubble / NoCode — ceiling at 10 users
- • Freelancers from Fiverr/Upwork — no ownership
Syntelligence Stack
- • Next.js 15 — React, SSR, App Router
- • Supabase — PostgreSQL, Auth, Realtime, Storage
- • Vercel — Edge hosting, auto-scaling, CI/CD
- • TypeScript — zero runtime errors
- • Stripe — payments, subscriptions, invoicing
Dlaczego ten stack? — we run it in production. Our own platform (CRM, Social Planner, Analytics) runs on the same stack. We do not experiment on your project.
What They Say Nasi Klienci
Prawdziwe opinie z Google.
Paweł to jedna z tych osób, z którymi po pierwszej rozmowie wiesz, że trafiasz na kogoś, kto naprawdę ogarnia temat. Bez lania wody, tylko konkret, co działa.
Can't say enough good things. Explained what I needed, Paweł came back with something even better than I imagined. Best money I've spent on my business this year, hands down.
Miałem przyjemność współpracować z Pawłem przy realizacji projektu audiowizualnego i z pełnym przekonaniem mogę go polecić każdemu, kto szuka profesjonalisty.
