High-Performance Web Applications Built for Enterprise Scale
Custom web development services from Wroclaw, Poland. I build fast, scalable web applications with Next.js, React, and TypeScript for global businesses.
What I Deliver
Core capabilities I bring to every web development engagement.
Server-Side Rendering & Static Generation
I leverage Next.js to deliver pages that load in under a second. SSR and ISR ensure your content is always fresh, SEO-friendly, and blazing fast at the edge.
Progressive Web Applications
Offline-first architectures with service workers, push notifications, and app-like experiences that work seamlessly across every browser and device.
API Design & Integration
RESTful and GraphQL APIs built for reliability. I integrate with payment gateways, CRMs, ERPs, and third-party services your business depends on.
Performance & Core Web Vitals
Every project is optimized for LCP, CLS, and INP from day one. I routinely deliver Lighthouse scores above 95 through code splitting, lazy loading, and edge caching.
Technology Stack
Battle-tested tools I rely on for web development projects.
My framework of choice for production-grade React applications with built-in SSR, routing, and API layer.
Component-driven architecture for complex UIs with predictable state management and a mature ecosystem.
End-to-end type safety that catches bugs at compile time and makes large codebases maintainable.
High-throughput backend services for real-time features, WebSocket connections, and API orchestration.
Battle-tested relational database for transactional integrity, complex queries, and scalable data modeling.
Edge deployment across global PoPs for sub-50ms TTFB, automatic preview deployments, and zero-config SSL.
My Process
A proven approach refined across dozens of web development projects.
Discovery & Requirements
I audit your existing systems, define technical requirements, and map out the architecture before writing a single line of code.
Prototyping & Design
Interactive prototypes validated with stakeholders. I finalize the UI system, component library, and data models.
Iterative Development
Two-week sprints with continuous deployment. You review working software every cycle, not slide decks.
Launch & Optimization
Performance audits, load testing, and staged rollouts. Post-launch monitoring ensures uptime and fast iteration.

Frequently Asked Questions
Common questions about my web development services.
For most projects, I recommend Next.js with TypeScript, PostgreSQL, and deployment on Vercel or AWS. This stack gives you server-side rendering for SEO, type safety across the codebase, and edge-deployed performance out of the box. I adapt based on your constraints — if you need real-time features, I add WebSockets; if you need heavy data processing, I bring in Redis or message queues.
An MVP typically takes 8–12 weeks from kickoff to launch. A full-featured enterprise application runs 16–24 weeks. I scope aggressively in the discovery phase to eliminate surprises, and I deliver working software every two weeks so you see progress immediately.
Absolutely. About 40% of my projects involve improving or extending existing applications. I start with a codebase audit to identify technical debt, performance bottlenecks, and security gaps, then propose a prioritized roadmap.
Every pull request goes through code review. I enforce strict TypeScript configs, automated testing (unit + integration), CI/CD pipelines with linting and type-checking gates, and performance budgets in Lighthouse CI.
With Sprinx, you get a senior engineer shipping production code from week one — no recruiting, onboarding, or management overhead. I operate in your tools (Slack, Jira, GitHub) and timezone overlap, so it feels like an extension of your team without the 6-month ramp-up.
