Full-Stack Development Agency — End-to-End Apps

Full-stack development covers the complete web application — the frontend (what users see and interact with), the backend (server logic and APIs), the database (data storage and retrieval), and the infrastructure (hosting, deployment, monitoring). A full-stack team can build an entire product independently.

Our primary stack is React or Next.js on the frontend, Node.js (Fastify or Express) on the backend, PostgreSQL for the database, and TypeScript throughout. We deploy on AWS, Vercel, or Railway depending on project requirements and team preferences.

For most startups and mid-size companies, a full-stack agency is more efficient — one team owns the entire product, context is shared, and there are no handoff gaps between frontend and backend teams. Specialists make sense at scale when individual layers have distinct team-sized complexity.

Yes. This is one of our core strengths. Kultrix builds multi-tenant SaaS products with subscription billing (Stripe), user management, team workspaces, admin dashboards, and the marketing site — all as a single coherent engagement.

We use PostgreSQL for relational data with Prisma ORM for type-safe queries and automated migrations. For high-read workloads we add Redis caching. For file storage we use AWS S3 or Cloudinary. Database design is treated as a first-class deliverable, not an afterthought.

Yes. We configure CI/CD pipelines (GitHub Actions), containerize applications with Docker, set up staging and production environments, configure monitoring and alerting, and document deployment procedures. Infrastructure is a first-class concern in every Kultrix engagement.

We separate concerns clearly from the start: feature-based folder structure, bounded service layers, typed API contracts, database migrations in version control. As apps grow, we introduce module boundaries, background queues, and caching before they become bottlenecks.

Yes. Kultrix offers team augmentation — embedding full-stack engineers directly into your team's Slack, sprint cycles, and code review process. This works well when you need senior capacity without the overhead of recruitment.

Yes. We regularly inherit legacy codebases — PHP, Ruby on Rails, older React/Angular apps — and modernize them incrementally. We write a technical assessment, identify the highest-risk areas, and create a migration roadmap that ships value throughout.

We enforce ESLint and Prettier in CI, require code review on all pull requests, write tests for critical paths, document architectural decisions in ADRs, and conduct quarterly code health reviews. Quality is a process, not a one-time event.

We work in two-week sprints with weekly demos. Every sprint delivers working software — not just progress updates. We use Linear for issue tracking and provide a live staging environment so stakeholders can review changes at any time.

An MVP with core features takes 8–12 weeks. A full-featured product launch takes 4–8 months. Kultrix breaks work into phases so you can launch early, gather feedback, and iterate — rather than waiting for a single big-bang release.
