Custom Web Application Development in Romania

We build personalized web applications for companies that have outgrown standard solutions: SaaS platforms, operational dashboards, B2B portals, internal systems, and enterprise platforms. Senior team, modern stack, agile delivery with 2-week sprints.

What we build — concretely

Custom web development means an application built for your business workflow, not adapted from a template. We work with companies in Romania, the EU, the UK, and the US that have specific needs not solvable by off-the-shelf SaaS products.

Multi-tenant SaaS apps

Subscription platforms, automated billing (Stripe, Paddle), permission management, white-label.

Dashboards & analytics

Admin interfaces with real-time charts, Excel/PDF exports, role-based access control.

B2B portals & marketplaces

Supplier integrations, product catalogs, order workflows, automated invoicing.

Internal systems (custom ERP/CRM)

Replace Excel and manual processes: approval flows, reporting, integration with external systems.

Education platforms (LMS)

Courses, video streaming, quizzes, certificates, per-module payments, community.

FinTech / EduFin apps

Trading platforms, paper trading, broker API integrations (Interactive Brokers, Alpaca), compliance.

Tech stack

We choose the stack based on project requirements, your existing ecosystem, and the team that will maintain the code after launch.

Frontend

  • React + Next.js 14 — for SEO-friendly apps, server components, edge rendering
  • Vue.js 3 / Nuxt — simpler alternative for Vue-friendly teams
  • TypeScript — strict mode, zero any tolerated
  • Tailwind CSS or CSS Modules — reusable design system

Backend

  • Node.js + Express/Fastify/NestJS — for end-to-end JavaScript APIs
  • Laravel (PHP 8.3) — for projects with complex Romanian integrations (e-Factura, ANAF, PayU)
  • Python (FastAPI / Django) — for AI/ML, data pipelines, scientific integrations
  • Bun — for performance-critical workloads

Databases & infrastructure

  • PostgreSQL (default), MongoDB, Redis for cache
  • Cloud: AWS, Google Cloud, Hetzner (cost-efficient EU)
  • CI/CD: GitHub Actions, GitLab CI, zero-downtime deploys
  • Observability: Sentry, Datadog, Grafana
€5,000 – €80,000+ EUR
Typical budgets for custom web projects (more for fixed-price, less for T&M).

Process — 2-week sprints

We use agile methodology with clear deliverables at the end of each sprint. You'll see progress within the first 2 weeks — no waiting months for a demo.

  1. Discovery (1-2 weeks): stakeholder workshops, user stories definition, wireframes, technical architecture, detailed estimate.
  2. Design (parallel with dev): UI/UX design in Figma, clickable prototype, reusable design system.
  3. Sprint 1: repository setup, CI/CD, authentication, first critical flow. Demo at sprint end.
  4. Sprints 2-N: incremental feature development, daily code reviews, automated tests, bi-weekly demos.
  5. UAT & launch: beta with real users, bug fixing, performance optimization, production deploy.
  6. Maintenance: SLA, 24/7 monitoring, security updates, new features on demand.

FAQ

How much does custom web application development cost?

Costs start at €5,000 for simple applications (MVPs, minimal dashboards) and reach €80,000+ for complex enterprise systems. Influencing factors: feature count, external API integrations, UX/UI requirements, timeline, team size.

Do you work fix-price or time & materials?

For projects with very clear scope (under €15,000), we work fix-price. For larger projects, we recommend T&M with transparent weekly reporting — flexibility to pivot without contract renegotiation.

What stack do you use?

Default: TypeScript + Next.js + Node.js/NestJS + PostgreSQL. We choose alternatives (Laravel, Django, Vue) when context calls for it. We never push a stack you cannot maintain after delivery.

How long does development take?

Simple MVP: 6-10 weeks. App with auth, payments, integrations: 3-6 months. Enterprise system: 6-12+ months.

Does the code remain mine?

Yes. The repository is yours from day 1, contract includes clear IP transfer. No «hidden code» that locks you in.
