I build scalable, type-safe web applications using a modern technology stack: Next.js for the frontend, NestJS for the backend API, Prisma as the ORM, and PostgreSQL for reliable data storage. From initial concept to production deployment, we deliver full-stack applications that are fast, maintainable, and secure.

WHO THIS SERVICE IS FOR

Startups needing a production-ready MVP with solid architecture

Growing businesses replacing legacy PHP, Ruby, or .NET applications

Teams requiring end-to-end TypeScript for developer productivity

E-commerce brands needing custom admin dashboards or internal tools

SaaS companies building subscription platforms with complex data models

TECHNOLOGY STACK OVERVIEW

Frontend: Next.js with App Router, React Server Components, and Tailwind CSS Backend API: NestJS with modular architecture, dependency injection, and guards Database ORM: Prisma with type-safe database queries and migrations Database: PostgreSQL with JSON fields, full-text search, and ACID compliance Deployment: Vercel, AWS, or Docker containers with CI/CD pipelines

CORE DEVELOPMENT SERVICES

Full-Stack Application Development Build end-to-end web applications with shared TypeScript types between frontend and backend. Includes user authentication, role-based access control, file uploads, email notifications, and payment processing via Stripe or PayPal.

API Design & Development Create RESTful or GraphQL APIs using NestJS with validation, serialization, and OpenAPI documentation. All endpoints are fully typed and tested with Jest.

Database Design & Optimization Design PostgreSQL schemas using Prisma with proper indexing, relations, and constraints. Implement database migrations, seeding, and query optimization for sub-50ms response times.

Authentication & Security Implement JWT authentication, refresh tokens, bcrypt password hashing, and session management. Add two-factor authentication, rate limiting, and CORS configuration.

Real-Time Features Add WebSocket gateways using NestJS for live chat, notifications, or collaborative editing. Integrate with Redis for pub/sub across multiple server instances.

Deployment & DevOps Set up CI/CD pipelines with GitHub Actions. Deploy to Vercel for frontend and AWS ECS, DigitalOcean, or Railway for backend. Configure environment variables, logging, and health checks.

DEVELOPMENT PROCESS

Discovery (2 to 3 days) Review requirements, define data models, create API specifications, and set up project structure with TypeScript strict mode enabled.

Database & Backend Setup (1 to 2 weeks) Initialize PostgreSQL database, define Prisma schemas, generate migrations, and build NestJS modules, services, and controllers.

Frontend Development (2 to 4 weeks) Build Next.js pages with Server Components and Client Components as needed. Integrate with backend API using fetch or tRPC. Implement responsive UI with Tailwind CSS.

Integration & Testing (1 week) Write unit tests with Jest and end-to-end tests with Playwright. Perform load testing and security audits.

Deployment & Launch (3 to 5 days) Set up production database, run migrations, configure environment secrets, and deploy with zero downtime.

Post-Launch Support (30 days included) Fix bugs, monitor performance, and provide knowledge transfer.

WHY THIS STACK

Type safety across entire application prevents entire categories of bugs. Prisma eliminates SQL injection and migration headaches. Next.js provides SEO benefits and fast page loads. NestJS offers enterprise-grade structure without boilerplate. PostgreSQL handles complex queries and scales to millions of records.
