Built Around How Your Business Works

Before any code gets written, I make sure we're solving the right problem.

Every project starts with understanding: what success looks like for you, who your users are, what constraints matter. Then prototyping, scoping, and building something that fits your business, not a template you'll outgrow.

You get direct access throughout the project. Questions get answered in hours, not days. Decisions happen fast. And at the end, you own code that actually reflects what you needed.

Fennaro: Dog Playmate Matching App

A dog-matching app I built solo, end to end, for owners of big and working breeds who struggle to find calm, compatible walks. It shows every nearby dog and ranks them by pairwise compatibility instead of hard-filtering anyone out, and it never stores an exact home address. Expo PWA, Hono/oRPC API, Neon PostGIS geo-matching, Better Auth, a moderation dashboard and full GDPR flows. Trilingual (EN, PL, PT-PT), Poland-first launch.

What I Build

Websites, SaaS, and E-Commerce: Built with React and Next.js

Custom software designed around your requirements. Every feature serves a purpose, and the codebase scales as you grow.

Web DevelopmentSaaS AppsE-CommerceSEO & PerformanceAI Integration
See ServicesView Projects

E-Commerce & Online Stores

Online stores with fast checkout, real inventory management, and payment processing that works across borders. Custom e-commerce platforms with full control over pricing, promotions, and customer experience.

SaaS & Web Applications

Web applications with user accounts, dashboards, permissions, and subscription billing. Architected to handle real users from launch, and structured so new features don't break existing ones.

Full-Stack Web Development

Business websites that load fast, rank well, and stay easy to update. Clean architecture that grows with your business, not something you'll need to rebuild in two years.

app/products/page.tsx
const products = await db.products.findMany()if (!products.length) return <EmptyState />return <ProductGrid items={products} />// Error boundary handles failures

SEO & Performance Optimization

Technical SEO focused on speed, structure, and search visibility. Core Web Vitals improvements, indexing fixes, and SEO optimization that Google rewards with better rankings.

AI Integration

AI features that solve real problems: automated email handling, document processing, intelligent search, workflow automation. Production-ready implementations using OpenAI, Anthropic, and Google APIs.

What clients usually ask before we start

What do you build?
SaaS platforms, custom e-commerce systems, and business websites. Every project is custom-built for your specific requirements. You own the code completely.
How long does a typical project take?
Small projects: 3-5 weeks. SaaS or e-commerce platforms: 8-12 weeks, depending on scope and integrations.
What's your pricing structure?
