Web App Development.
Modern web applications built with the latest technologies. From responsive websites and complex dashboards to full-fledged SaaS platforms – scalable, secure, and future-proof.
A web app is often the most important touchpoint between you and your customers today — faster than an app, cross-device, no store hurdle. We build web applications that don't just run in the demo but still run productively three years later: typed code, automated tests, observable performance, backups that actually restore. From the MVP for investors to a mature SaaS platform with thousands of users.
Full-stack web development with the latest technologies. We build web applications that are fast, secure, and scalable – from the API through the backend to the frontend.
Typical Use Cases
Where we typically deploy this service
SaaS Platforms with Multi-Tenancy
Multi-tenant architecture with isolated data per customer, self-service onboarding, Stripe integration for recurring billing, admin panel for your team. Scales from the first customer into the four-digit range.
Dashboards and Admin Tools
Aggregate data from multiple sources, display it in real time, add filters and export. Role-based permissions, audit log, everything under your control — no per-seat SaaS fees.
Headless CMS and Content Platforms
Marketing site, blog, product catalog — all editable via your own admin panel (CMS experience like WordPress, but modern). Example: techlogia.de itself runs on exactly this architecture.
Why techlogia
What sets us apart on this service
TypeScript End-to-End
From database schema (SQLAlchemy + Pydantic) to frontend (TypeScript + Zod), one continuous type system. Schema drift between API and client is caught at compile time, not in production.
Performance Budget Built In
Lighthouse score above 90 is mandatory, not a goal. Image optimization, code splitting, ISR caching, HTTP/2 server push — all default-on, not premium features.
Host Wherever You Want
Hetzner VPS in Germany, your own infrastructure, or a Kubernetes cluster — the app is Docker Compose-portable. No vendor lock-in to our servers.

FAQ
Answers to the most important questions on this service
An MVP with login, data model and first main flows: 6–10 weeks. A full SaaS platform with multi-tenancy, billing and admin: 4–6 months. Weekly sprint reviews, clickable prototype typically available after 2–3 weeks.
Vertical scaling (larger VPS) usually covers the first years. When needed: read replica for the database, Redis cluster for sessions, load balancer with horizontal app scaling, CDN for static assets. The architecture is prepared from day one without exploding the initial budget.
Alembic for schema migrations, every change versioned, discussed in code review, tested in staging. Rollback scripts are mandatory. Data migration runs in transaction-wrapped batches so production traffic isn't blocked.
