SaaS Development
Scalable, multi-tenant B2B architectures engineered for growth.
Building a SaaS platform requires complex engineering: subscription billing, secure multi-tenant data partitioning, granular role-based permissions, and optimized database indexing. I engineer robust SaaS foundations that support thousands of concurrent users across isolated workspaces without buckling under load.
Core Capabilities for High-Retention Platforms
- Need multi-tenant isolation with strict Row Level Security (RLS).
- Complex recurring subscriptions, metered usage billing, and enterprise invoicing.
- High data throughput requiring background job workers and real-time websockets.
Execution Architecture
System Architecture
Designing secure multitenant data models using RLS (Row Level Security), robust caching strategies, and global state management.
Billing & Subscriptions
Integrating metered billing, customized enterprise plans, and global payment processors (Stripe, Paddle).
Performance Engineering
Establishing background queue systems for heavy processing, database read replicas if needed, and fast CDN edge caching.
Scalable Deployment
Containerized deployments and structured CI/CD pipelines to ensure isolated branch testing and zero-downtime updates.
Core Technical Stack & Tooling
Investment & Engagement Terms
Comprehensive SaaS foundations typically start around $30,000 to $50,000, depending on the complexity of permissions, integrations, and compliance requirements.
Trusted Across Critical Deployments
Verified client testimonials from founders and engineering directors who relied on Shubham's systems.
"Shubham stepped in when our internal team was bottlenecked. He re-architected our high-concurrency ingestion pipeline in three weeks and handed over production-ready software with flawless documentation."

You own the system.
The code. The infra. The data.
Software should not become valuable enough to matter and then be impossible for the client to own or operate.
Everything I build is 100% client-owned intellectual property from day one. You own the code, the accounts, the infrastructure, and the data. No vendor lock-in.
