Custom Web Application Development

I design and build custom web applications end-to-end — from initial architecture through deployed, production-ready product.

When off-the-shelf software forces your team into workarounds, a custom web application eliminates the gap between how your business actually operates and how your tools expect it to operate.

I design and build custom web applications end-to-end — from initial architecture through deployed, production-ready product. Every application I deliver is built for real workloads, documented for your team, and engineered to run independently after handoff.

What I Build

Enterprise Portals & Internal Tools

Custom dashboards, admin panels, and operations management systems. Role-based access, audit trails, and workflow automation.

See OpsPortal →

SaaS Products & MVPs

Full-stack SaaS from validation through launch. Multi-tenancy, subscription billing, user management, and scalable API architecture.

E-Commerce Platforms

Custom e-commerce beyond Shopify limitations. Multi-channel inventory, AI-powered product analysis, and complex pricing rules.

Data-Heavy Applications

Investment platforms, analytics dashboards, and applications where data integrity and real-time processing are non-negotiable.

Technology Stack

I choose technology based on your project requirements — not based on what's trending. That said, my core stack delivers the best balance of development speed, performance, and long-term maintainability for most custom web applications:

Frontend

React, Next.js (App Router), TypeScript, Tailwind CSS
Server-side rendering for SEO, type safety that prevents bugs at scale, and a component architecture that makes your codebase maintainable by any React developer after handoff.

Backend

Laravel (PHP), Node.js, Python
Laravel handles complex business logic, authentication, and database operations faster than any framework I've worked with in 17 years. Node.js for real-time features. Python for AI/ML integrations.

Database

PostgreSQL, Supabase, MongoDB, Redis
PostgreSQL handles 95% of use cases with superior data integrity. Supabase when you need real-time subscriptions. Redis for caching and session management.

Infrastructure

Vercel, Railway, Docker, AWS
Vercel for Next.js applications (zero-config deployments, edge functions). Railway for backend services. Docker when you need full infrastructure control.

How Custom Web Application Development Works
01

Discovery & Architecture

I start every project by understanding what problem your application needs to solve — not what features you think it needs. This distinction matters because feature lists lead to bloated software; problem definitions lead to applications that people actually use.

Technical specification document, database schema design, API architecture diagram, and a realistic timeline with milestones.
02

Design & Prototyping

UI/UX design that prioritizes clarity over decoration. Every interface element exists because it helps users complete a task — nothing decorative, nothing confusing. I design in Figma with a component-based system that translates directly to code.

Interactive Figma prototype, design system with tokens and components, responsive layouts for desktop and mobile.
03

Development

Full-stack implementation with continuous deployment. You see progress in real-time through staging environments — not screenshots in email threads. Weekly progress demos, direct communication, no project managers in between.

Working application with automated tests, CI/CD pipeline, staging environment with your data.
04

Testing & Launch

Comprehensive QA, performance optimization, security audit, and production deployment. I don't consider a project done until it's running under real conditions with real users.

Production deployment, monitoring setup, documentation, and a handoff session with your team.
What Custom Web Application Development Costs
MVP / Proof of ConceptStarting from €8K

Core functionality, 1-2 user roles, essential integrations. Ideal for validating a business idea before full investment.

4-6 weeks
Business ApplicationStarting from €15K

Full feature set, multiple user roles, third-party integrations, admin dashboard.

8-14 weeks
Enterprise PlatformStarting from €40K

Multiple interconnected modules, complex business logic, high-availability requirements, advanced analytics.

Why Work With a Solo Senior Developer

Direct communication. You talk to the person who writes the code. No telephone game through project managers and team leads. Questions get answered in hours, not days.

Consistent quality. One architect, one codebase style, one quality standard. No handoffs between junior developers who interpret requirements differently.

Real accountability. When one person is responsible for every layer — design, frontend, backend, database, deployment — nothing falls through the cracks between teams.

Cost efficiency. My daily rate reflects 17 years of experience, not the overhead of an office, sales team, and management layer. You pay for engineering, not bureaucracy.

These ranges assume a solo senior developer (me). Agencies charge 2-3x more because you're paying for account managers, junior developers, and office overhead. Read more about web application development costs →

FAQ

A website primarily displays information — a corporate site, a blog, a landing page. A web application handles complex logic — user accounts, dashboards, data processing, real-time features. I build both, but web applications are where my architecture expertise really shines.
An MVP takes 4-8 weeks. A full-featured application takes 8-16 weeks. Complex enterprise systems with integrations can take 3-6 months. I always provide a detailed timeline before we start.
Yes, and I particularly enjoy it. I help you identify the smallest functional core of your idea, build it fast, and get it in front of real users. If it validates, we scale. If not, you've invested weeks instead of months.
My primary stack is Next.js with TypeScript for frontends and Laravel or Node.js for backends, with PostgreSQL as the database. This combination offers excellent developer experience, performance, and scalability. I choose the specific tools based on your project's requirements.
Yes. I regularly take over codebases from other developers or agencies. I start with a technical audit — code quality, architecture, security, performance — and then propose either improvements or a strategic rebuild.
