Krunal P
About this gig
Most SaaS startups fail because they hire agency mills that outsource to junior devs, resulting in fragile codebase that must be rewritten when scaling.
Build it right the first time.
I am Krunal, an independent Senior Full-Stack Architect with 13+ years of experience. When you hire me, you work directly with a lead architect who designs your PostgreSQL database, writes strict TypeScript, and engineers fault-tolerant APIs.
What I Architect & Build:
Custom React & Next.js Web Applications
High-Performance Node.js & TypeScript APIs
Relational PostgreSQL Schemas via Prisma ORM
Multi-Tenant SaaS, Stripe Billing & Auth RBAC
Redis Caching & Global Error Handling
The Production-Ready Standard:
No fragile prototypes. Every system includes strict type-safety, zero-downtime CI/CD deployment, and clean architecture so your platform scales effortlessly under heavy traffic. You hold 100% intellectual property and code ownership.

FAQ
Do you outsource my code to junior developers or an agency?
ever. I am an independent Senior Architect with 13+ years of experience. You work directly with me—the engineer designing your PostgreSQL schemas, writing your TypeScript, and configuring your APIs. No middlemen or junior handoffs.
What tech stack do you use to build SaaS platforms?
I specialize in enterprise-grade stacks: React or Next.js for the frontend, Node.js with strict TypeScript for backend APIs, and PostgreSQL via Prisma ORM for the database, combined with Redis for caching and Stripe for subscriptions.
Will I have full ownership of the source code and IP?
Yes, 100%. Upon project completion and final payment, you retain absolute intellectual property rights and full ownership of the entire codebase, database models, and deployment configurations.
What is included in the $1,500 Architecture Blueprint?
The Blueprint is for founders needing a technical roadmap before development. I map your API endpoints, design relational PostgreSQL schemas, select optimal cloud services, and build a phased architecture plan ready for engineering.
Can you integrate Stripe billing, auth, and 3rd-party APIs?
Yes. I implement secure OAuth/JWT authentication, role-based access control (RBAC), Stripe subscription checkout with automated webhook synchronization, and custom 3rd-party/AI API bridges with strict error handling.
