Coderia.it is one person — a full-stack developer who single-handedly builds custom web applications, mobile apps (React Native) and scalable SaaS systems. I run the full delivery cycle — from business analysis, through UI/UX and back-end, to cloud deployment, SEO and long-term support.
End-to-end software development — custom web apps, mobile apps (iOS & Android), SaaS platforms, AI automation and technical SEO. One person, every layer, zero handover friction.
I build mobile apps for iOS and Android in React Native — one codebase, two platforms, near-native performance. Offline-first architecture, biometric authentication, real-time sync over WebSockets, push notifications and smooth publishing to the App Store and Google Play.
I build scalable web apps and SaaS platforms in Next.js 15 and Laravel 11. Role-based auth, real-time dashboards, REST and GraphQL API design, multi-tenant architecture, subscriptions (Stripe / PayU), automated tests, Docker containerisation and cloud deployments with CI/CD.
I integrate AI agents and LLM-powered features directly into apps, automate business processes with n8n and Make, and connect external APIs via webhooks. In parallel I run technical SEO audits — structured data, XML sitemaps, Core Web Vitals and mobile-first indexing.
Selected projects I designed, built and deployed on my own. From MVPs to platforms serving thousands of users a day.
Web app · Marketplace
Poland's largest hair-selling platform. A two-sided Next.js marketplace: buyer and seller accounts (NextAuth), listings with galleries, VIP promotion and a search filtered by region, colour, texture, length and weight.
Corporate site · B2B
An aerial-platform rental portal with a catalogue of over 280 machines. A custom plugin handling quote inquiries and lead capture, a child theme for the bespoke design and a LiteSpeed server for fast loading.
Web app · SaaS
A full-stack enterprise SaaS web app in Next.js 15. Real-time dashboard over WebSockets (Soketi), role-based auth (NextAuth), an advanced PostgreSQL schema with Prisma and a Dockerised deployment.
Online store · E-commerce
A WooCommerce supplement store with a catalogue of thousands of products. Four language versions, PayPo deferred payments, wishlists, a customer-review module and aggressive asset caching for peak traffic.
Web app · AI
An AI product generating personalised development reports from NASA JPL astronomical data. An interactive React configurator, LLM-driven content generation, encrypted online payments and full PL/EN bilingualism.
Practical knowledge about app development, performance and SEO. No clickbait — just real lessons from real deployments.
