Full Stack Development: End-to-End Web & API Engineering for Modern Businesses
What is Full Stack Development?
PiTangent’s full-stack engineering teams are highly skilled across Angular, Vue.js, React.js, Node.js, Python, Java, and .NET on both frontend and backend layers. With full-stack development, our clients achieve more at the cost they like to spend – a single team with superior functional understanding of integrations between software stacks at every layer, from database schema to pixel-perfect interface.
Types of AI Agents We Build
Full Stack Web Application Development
End-to-end web application development - React or Next.js frontend, Node.js or Python backend, PostgreSQL or MongoDB database, and AWS cloud deployment - built by one team, accountable for every layer, with CI/CD from the very first sprint.
REST & GraphQL API Development
Production-grade REST and GraphQL APIs with authentication, rate limiting, caching, versioning, and comprehensive documentation. We design and build APIs that are easy to consume, easy to extend, and built to handle production traffic from day one.
Admin Panels & Internal Business Tools
Custom admin dashboards, internal portals, and business management tools that replace spreadsheet-based workflows - multi-user roles, approval flows, real-time data visualisation, and bulk export capabilities tailored to your team's exact needs.
SaaS Product Development
Multi-tenant SaaS web applications with user authentication, subscription billing (Stripe/Razorpay), role-based access control, onboarding flows, analytics dashboards, and the architecture to support your first 100 customers and your first 100,000.
API Integration & Third-Party Connectivity
Connecting your web application to the services it needs - payment gateways, CRMs, ERPs, logistics platforms, communication APIs, analytics tools, and custom third-party services - using REST, GraphQL, webhooks, and custom middleware built for reliability.
Legacy Application Modernisation
Migrating legacy web applications from outdated frameworks to modern, maintainable stacks - phased re-architecture to React frontends, RESTful API layers, modern databases, and cloud-native infrastructure - without disrupting your existing users during the transition.
Full Stack Development by Business Size
Full Stack for Startups
Lean, production-ready web applications and APIs built to validate your idea with real users – from brief to launch in as few as 8 weeks, on a stack that scales with your growth without a rebuild.
- • React/Next.js + Node.js or Python – production-grade from day one
- • CI/CD pipeline and cloud deployment on AWS or Vercel included as standard
- • Authentication, database, and REST API – all in a single sprint-based build
- • Codebase designed to scale from 100 to 100,000 users without re-architecture
Starting from
$8,000
8–12 weeks
Full Stack for SMBs
Custom web platforms and portals that replace spreadsheets and manual operations – multi-user roles, workflow automation, third-party integrations, and data dashboards built around your exact business processes.
- • Multi-user role management, permissions, and approval workflows
- • Payment gateway integration (Stripe, Razorpay, PayPal) and subscription billing
- • Third-party API integrations: CRM, ERP, accounting, logistics, and marketing tools
- • Custom admin dashboard with real-time reporting and bulk data management
Starting from
$25,000
12–20 weeks
Full Stack for Enterprises
Large-scale web platforms and API systems with microservices architecture, SSO, compliance controls, and a dedicated engineering squad – built to handle enterprise-level traffic, audit requirements, and system complexity.
- • Microservices and API-first architecture for long-term flexibility and scalability
- • SSO (SAML, OAuth), SCIM provisioning, audit trails, and GDPR-compliant data handling
- • Kubernetes/Docker containerisation, auto-scaling, and multi-region cloud deployment
- • Dedicated full-stack squad with SLA-backed delivery and monthly architecture reviews
Starting from
$80,000
4–9 months
Our Full Stack Technology Stack
Industry-proven frameworks and platforms for production-grade applications at any scale.
What Full Stack Engineering Makes Possible
When the frontend, backend, and infrastructure are built by one team - this is what changes.
Ship new production features in every 2-week sprint - no handoff delays between frontend and backend teams
Connect any third-party API - payment, CRM, ERP, or custom - in a single sprint, fully tested
Scale from 100 to 100,000 concurrent users without rebuilding the architecture from scratch
Deploy to cloud infrastructure with automated CI/CD from the very first sprint, not after launch
Replace manual spreadsheet workflows with a custom admin dashboard in 4–6 weeks
Migrate a legacy application to a modern stack incrementally - without taking it offline for users
