Full-Stack SaaS & Web App Development | Next.js + Node.jsHalil Aydin
Full-stack product development from interface to production
I build production-ready SaaS products and web applications using Next.js, React, Node.js, TypeScript, and PostgreSQL.
I can take ownership across the product stack, including complex frontend interfaces, APIs, authentication, role-based access, databases, payments, third-party integrations, and deployment.
I can join an existing product that needs experienced engineering support or build a new application from a defined scope.
What I can help you build
SaaS products and customer-facing web applications
Admin panels, dashboards, and internal operational tools
Authentication, teams, roles, and permission systems
REST APIs, backend workflows, and database-driven features
Payments, webhooks, email, analytics, and third-party integrations
Existing product features, refactoring, and technical improvements
Production deployment and environment configuration
What you get
Production-ready frontend and backend implementation
Reusable, typed, maintainable application code
Responsive interfaces for desktop, tablet, and mobile
API and database integration based on the agreed scope
Loading, error, empty, and permission states where required
Deployment-ready project and environment configuration
Clean handoff with source code and technical context
How I work
We start by defining the product requirements, existing constraints, integrations, and the smallest useful scope to build first.
Scope and architecture: We agree on features, technical requirements, data flow, and delivery priorities.
Build and review: I implement the product in focused iterations with working progress you can review.
Test and deliver: I complete the agreed scope, handle final integration and deployment work, and prepare the project for continued development.
Good fit for
Founders and product teams building SaaS platforms, operational tools, e-commerce systems, internal applications, dashboards, or API-driven products.
Also a good fit if you already have a working application and need someone who can understand the existing codebase and contribute across both frontend and backend without rebuilding everything from scratch.
