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.

01

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.

02

Progressive Web Applications

Offline-first architectures with service workers, push notifications, and app-like experiences that work seamlessly across every browser and device.

03

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.

04

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.

Next.js

My framework of choice for production-grade React applications with built-in SSR, routing, and API layer.

React

Component-driven architecture for complex UIs with predictable state management and a mature ecosystem.

TypeScript

End-to-end type safety that catches bugs at compile time and makes large codebases maintainable.

Node.js

High-throughput backend services for real-time features, WebSocket connections, and API orchestration.

PostgreSQL

Battle-tested relational database for transactional integrity, complex queries, and scalable data modeling.

Vercel

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.

01

Discovery & Requirements

I audit your existing systems, define technical requirements, and map out the architecture before writing a single line of code.

02

Prototyping & Design

Interactive prototypes validated with stakeholders. I finalize the UI system, component library, and data models.

03

Iterative Development

Two-week sprints with continuous deployment. You review working software every cycle, not slide decks.

04

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.
