Software Development Services

Full Stack Development Services

Full stack development with a single accountable team across frontend, backend, and infrastructure.

Delivery focus

Built to move from idea to production.

Our full stack development services give you a single accountable team across frontend, backend, and infrastructure, which reduces handoff delays and keeps architecture decisions consistent end to end. The work sits inside Software Development Services and is scoped, built, reviewed, and handed over as one engagement.

Scope

ClickMasters builds complete full stack web applications for B2B companies across the USA, Europe, Canada, and Australia. Next.js frontend with TypeScript and Tailwind. Node.js or Python backend with REST or GraphQL APIs. PostgreSQL database with Prisma ORM. Redis caching and BullMQ queues. AWS deployment with CI/CD. One team. One engagement. One product.

What is Full Stack Development?

Full stack development encompasses both frontend (UI) and backend (server, APIs, DB) of an application delivered by one team. This eliminates handoff friction between vendors where APIs become negotiation surfaces rather than engineered contracts. Our full stack applications are built with end-to-end TypeScript, ensuring that a database schema change is caught by the compiler in the frontend component before it ever reaches production.

SaaS Architecture Decisions: We Get Right

Critical decisions made in week one determine long-term velocity. We guide you through:

  • Row-Level Security: Database-enforced tenant isolation (safer than app-level filters)
  • tRPC: Type-safe internal APIs that eliminate REST/GraphQL boilerplate
  • Stripe Billing: Complete subscription lifecycles, trials, and dunning flows
  • Testcontainers: Testing against real PostgreSQL instances, not mocks

What this engagement delivers

SaaS Product Development

Complete SaaS platforms built for multi-tenancy. Organisation-scoped data (PostgreSQL RLS), Stripe Billing integration, admin dashboards, and automated onboarding flows.

B2B Internal Tooling

Custom dashboards for operations teams. CRUD interfaces, multi-step approval workflows with audit logs, and unified reporting over siloed data sources.

Full Stack MVP

Validate core user flows end-to-end in 8-14 weeks. Next.js + Fastify/tRPC + PostgreSQL. Deployed to AWS with CI/CD from day one for investor-ready progress.

Web Application Rebuild

Modernising legacy monoliths. Migrating jQuery/PHP/AngularJS apps to React + Next.js + Node.js with data integrity preservation and incremental traffic cutover.

Full Stack API Platforms

Public-facing APIs with developer portals. Webhook management, SDK generation from OpenAPI specs, and interactive documentation for integration partners.

Real-Time Applications

Collaborative tools with WebSocket sync (Socket.io), optimistic UI updates, conflict resolution (CRDT/Yjs), and real-time presence indicators.

Process

  1. Phase 1 · Week 1-2

    Architecture Design

    Defining user stories, data models, API contracts (REST/tRPC), and auth architecture in a comprehensive document.

  2. Phase 2 · Week 2-3

    Foundation Setup

    Setting up Next.js, Fastify/tRPC, Prisma, AWS ECS, and CI/CD pipelines to ensure every feature is built on production-ready infra.

  3. Phase 3 · Week 3-10

    Agile Feature Build

    Sprint-based development: DB migration → Backend procedure → Frontend component → E2E test for every feature.

  4. Phase 4 · Week 7-11

    External Integrations

    Implementing Stripe Billing, Resend/SES email, S3 file storage, and third-party CRM/ERP API connections.

  5. Phase 5 · Week 9-12

    Audit & Optimization

    Mandatory Lighthouse 90+ performance gate, WCAG 2.1 AA accessibility audit, and OWASP API security review.

  6. Phase 6 · Week 11-14

    Load Testing & Launch

    k6 load testing for P95 latency validation, production cutover, and 30-day hypercare support phase.

How we work

Engineering Cohesion

One team owns the full lifecycle | Basic: Handoff friction between vendors

Type Integrity

TypeScript End-to-End | Basic: API contract mismatches

Data Isolation

DB-Level RLS Tenancy | Basic: Risky app-level filtering

Validation Depth

Real DB in tests (Testcontainers) | Basic: Mocks that hide bugs

Infrastructure

AWS + Vercel (Best of breed) | Basic: Single-vendor compromise

Where this is used

Multi-Tenant SaaS

PostgreSQL RLS for data isolation, Stripe for subscriptions, and feature flags per pricing tier.

Fintech & Payments

Idempotent APIs, immutable audit logs, and PCI-aligned service isolation with strict TypeScript.

Healthcare & MedTech

HIPAA-compliant RLS architecture, encryption at rest/transit, and WCAG 2.1 AA clinical interfaces.

Headless Commerce

Next.js SSG/ISR for speed, Stripe processing, and BullMQ for order lifecycle events.

FAQs

What is full stack development?

Full stack development covers the entire application from the user interface (frontend) to the server, APIs, and database (backend). One team owns the entire product lifecycle.

What is the best full stack technology stack?

For B2B apps, we recommend Next.js + Node.js (Fastify/tRPC) + PostgreSQL + Prisma + TypeScript for end-to-end type safety and performance.

What is tRPC and when should I use it?

tRPC is a TypeScript-native RPC library that enables type-safe communication between frontend and backend without REST/GraphQL boilerplate. Ideal for monorepo projects.

How do you handle multi-tenancy?

We use PostgreSQL Row-Level Security (RLS) to enforce data isolation at the database level, ensuring users can only see their organization's data.

How much does full stack development cost?

Full stack MVPs range from $20k-$55k, while complete SaaS products range from $35k-$100k+ depending on complexity and features.

Do you handle cloud deployment?

Yes. We include full AWS ECS Fargate + Vercel setup with CI/CD, managed databases (RDS), and observability (Sentry/Grafana) as standard.
