Web applications built to support your business
Oberig.com develops SaaS platforms, portals, dashboards, e-commerce systems, and internal tools, whether you need a full product build or an engineering team to turn existing plans into working software.
Web apps we build most often
From a 6-week MVP to a platform serving thousands of users. Same team, same standards.
SaaS platforms
Multi-tenant architecture, subscription billing, role-based access, analytics, API-first design. Built to scale without a full rewrite at 10,000 users.
- Multi-tenant architecture with data isolation - each customer's data isolated at the database level, no shared tables
- Subscription billing (Stripe, Paddle, custom) - plan management, trials, upgrades, usage-based pricing
- Admin panels, analytics, and user management - super-admin, per-tenant dashboards, roles and permissions
- API-first design for integrations and mobile - REST and GraphQL documented from day one, same API for all clients
Enterprise dashboards & portals
Custom dashboards, CRMs, ERPs, and internal tools with real-time data. We replace spreadsheets with systems people on your team actually want to use.
- Real-time data visualization and reporting - WebSocket-powered live charts, configurable KPI widgets, scheduled exports
- Role-based access and audit logging - granular permissions per module, every change stamped for compliance
- Integration with ERP, CRM, and legacy systems - SAP, Oracle, Salesforce, HubSpot, or your custom API
- Automated workflows and notifications - threshold alerts, approval chains, Slack and email triggers
E-commerce & marketplaces
Online stores, multi-vendor marketplaces, B2B ordering platforms. Payments, shipping, inventory, CRM: all connected, all built to convert.
- Custom storefronts and product catalogs - headless architecture, search, filters, variants, bundles
- Payment gateways (Stripe, PayPal, local providers) - PSD2-compliant, 3DS, saved cards, subscription flows
- Inventory management and order fulfillment - real-time stock, multi-warehouse, 3PL integrations
- Multi-vendor marketplace architecture - vendor onboarding, commission splits, per-seller dashboards
MVPs & prototypes
A functional MVP in 6–12 weeks: real architecture, real users, real feedback. Scoped tightly so you validate the idea without overbuilding it.
- Working product in 6–12 weeks - fixed timeline, honest scope, no moving goalposts
- Investor-ready demos and pitch support - stable demo environment, technical due diligence documentation
- Architecture designed to scale post-MVP - modular structure, clean API boundaries, no rewrite needed
- User testing and feedback integration - analytics, session recording, feature flags from day one
Legacy modernization & migration
Incremental upgrades or a full rebuild, your choice. We audit what exists, map what's worth keeping, and modernize without downtime or lost business logic.
- Architecture audit and modernization roadmap - written report with phase-by-phase plan and risk assessment
- Incremental migration using strangler fig - old system stays live while new one takes over piece by piece
- Database migration with zero data loss - sync validation at every step, tested rollback plan ready before cutover
- Cloud migration and performance optimization - lift-and-shift first, then optimize; cost modeled before we start
Full build or development support
Use Oberig as a full product team or as the engineering part of your existing process.
Full product build
We take the project from technical planning through development, integrations, launch, and support. Best when you need one team responsible for delivery end to end.
Development from existing plans
Already have designs, specs, a backlog, or an internal product owner? We join as the engineering team and turn the plan into working software.
Team extension
Add frontend, backend, DevOps, or full-stack developers to your current team when you need more delivery capacity without hiring locally.
Legacy takeover
We audit the existing system, stabilize it, document what matters, and modernize it step by step without breaking production.
Web apps we have built
A few examples from the last few years. Client names stay confidential, results do not.
Luxury car rental platform
Problem: A premium UK rental brand was relying on an outdated booking system that no longer matched the way the business operated. It was inconvenient for the team, offered limited flexibility, and made day-to-day booking management harder than it needed to be.
Solution: We built a custom booking platform with real-time availability, dynamic pricing, centralized fleet management across all locations, and a straightforward checkout flow for customers.
Renewable Energy
EU collaboration & strategy platform
Problem: A European renewable energy marketplace needed a platform to connect buyers and sellers. The matching process, negotiations, and deal flow all had to happen in one place.
Solution: We built a custom marketplace on Vue.js/Nuxt where energy projects are listed with full descriptions, suppliers can submit offers and propose pricing, and both sides can communicate directly inside the platform.
On-demand services marketplace
Problem: A Swiss startup needed a two-sided marketplace connecting service providers with customers. Different user types required separate interfaces, and the admin side had to give full visibility without constant manual intervention.
Solution: We built a web platform with distinct interfaces for customers, providers, and admins. Automation handled the repetitive parts of the deal lifecycle end to end.
Why build with us
20+ years of web
Building web apps since 2001. Before React, before cloud, before SaaS was even a word. Every technology cycle, every hype wave, still shipping.
Development team that owns delivery
Frontend, backend, DevOps, QA support, and project coordination when needed. We can take the full technical delivery or join your existing product process.
Built for production use
Even MVPs are built with clean architecture, tested releases, monitoring, and a path for future development. Load testing, security reviews, on-call support: not "phase 2."
Transparent delivery
Agile sprints with demos every 1–2 weeks. You see working software, not slide decks. Budget tracking, burndown charts, and honest communication.
Web apps across domains
Examples of platforms, portals, and systems delivered across different markets.
FinTech
Trading platforms, payment processing, wealth management dashboards, compliance automation, banking portals, and lending systems.
EdTech
Learning management systems, virtual classrooms, assessment platforms, student portals, and content delivery systems with video streaming.
Healthcare
Patient portals, telemedicine platforms, EHR integrations, appointment scheduling, and HIPAA-compliant data processing systems.
E-commerce
Custom storefronts, B2B ordering platforms, multi-vendor marketplaces, inventory management, and subscription box services.
Real estate
Property listing platforms, booking engines, tenant portals, property management systems, and virtual tour integrations.
Enterprise
Custom CRMs, ERPs, project management tools, document management systems, and internal operations platforms.
Web development questions
How long does it take to build a web application?
A focused MVP usually takes 6 to 12 weeks. A full production application typically takes 3 to 6 months. Complex enterprise platforms may take 6 to 12 months. We work in agile sprints, so you see working software every 1 to 2 weeks, not at the end.
What technologies do you use?
Frontend: React, Next.js, Vue.js, Angular, TypeScript. Backend: Node.js, Python (Django, FastAPI), Java, .NET. Databases: PostgreSQL, MongoDB, Redis. Cloud: AWS, Google Cloud, Azure, Vercel. Stack fits the project, not the trend.
How much does web application development cost?
An MVP starts from €15,000–30,000. A mid-complexity SaaS platform costs €40,000–100,000. Enterprise systems range from €80,000 to €250,000+. Detailed estimate after a free discovery call. No guesswork, no padding.
Do you provide post-launch support?
Yes. Ongoing maintenance, bug fixes, performance tuning, new features, 24/7 monitoring. Most clients stay with us long after launch. Products keep growing, and so does the partnership.
Can you redesign or rebuild our existing application?
Yes. We regularly take over legacy systems, audit their architecture, and either incrementally modernize or rebuild from scratch. We migrate data, preserve business logic, and ensure zero downtime during transition.
Can you work with our existing team?
Yes. Many projects start with extending an existing team. A React developer here, a DevOps engineer there, or a full squad for a new feature stream. Your tools, your process, your standup.
How do you handle security?
Security is built in from sprint one. OWASP proven approaches, implement authentication (OAuth2, SSO), encrypt data at rest and in transit, run regular security audits, and comply with GDPR. For healthcare and fintech, we meet sector-specific compliance requirements (HIPAA, PCI DSS).
Do you build APIs?
Yes. It is a core part of almost every project. REST and GraphQL. Clean documentation (OpenAPI/Swagger), versioning, rate limiting, auth. Plus third-party integrations: payments, analytics, CRM, shipping, whatever your product needs to talk to.
What's your approach to testing?
Unit tests, integration tests, full-cycle tests. Written during development, not crammed in before launch. Jest, Cypress, Playwright, k6 for load testing. Every PR goes through code review and CI/CD before it touches main.
